BQG! Old one maxed
Can I respace my 130mm rear hub to 128? It's a cup and cone claris system and I want to use it on my late 80's model bike that currently has 6 speed. Can't set the frame as it's aluminum.
>>906715
Yes, you can respace a Shimano 130mm hub to 126mm by taking 4mm of washers off the non-driveside and then redishing the rim (note that this will slightly weaken the wheel overall). Be aware that unless you have unusually thick dropouts, you'll either need to cut the axle down a bit, or borrow one made for a 126 hub, otherwise the end of the axle made for 130 spacing will protrude and prevent you from closing your QR skewer.
>>906732
Ahhh I see. Doesn't sound too bad! Pic is project, gonna take my 8 Speed Mavic CXP22 wheelset off my other bike and build up an 11 speed set for it, then put the 8 speed on this!
Although it would be ridiculous, I suppose I could run 10 speed on this hub with friction too couldn't i?
is commuting 25 miles on a single speed a sensible idea?
>>906756
Knee cartilage is temporary, but hipster street cred is forever.
>>906761
notice i said single speed and not fixed gear, there is a difference, my friend. wouldnt call pic related hipster would you?

Utility bike with no IGH?
Currently looking at replacing my brake and gear cables.
The current cables have short lengths of uncovered inner cable running along the top and down tubes. What's the point of this arrangement? Is there any downside to drilling out the cable terminating braze-ons and routing the covered cable all the way through?
>>906771
It will look ugly, also more friction
>>906771
Weight, aesthetics, friction
>>906755
always 10 speed for friction might be pushing it - you'd likely get used to it tho ?

New thread, new post
Just to be sure: my rims are 622/19 and my tire 622/42. Is the Schwalbe AV17 the right size?
>>906820
>>906823
No i meant the inner tube. but thanks, this is helpful in an other way
>>906820
http://www.schwalbetires.com/node/662
Schwalbe says it is.
>>906835
Thanks!
>>906776
well I could try it for awhile, worst case I overshift a bit, not planning to compete on the bike anytime soon
>>906823
Fuck this chart.
I just went out and bought these thick, 32mm tires because Sheldon Brown said they'd fit.
Oh they fit the rim fine, but it rubs past my fork every few rotations.
Fitting the rim is not the whole story.
>>906984
It's not Sheldon's fault you're retarded, anon.
>>906984
>>906984
u dumb
also yr wheel is out of true
>>906984
M8.......
>>906771
The exposed cable is exposed because it runs in a straight line so it doesn't need housing. Housing is needed other places to keep the cable tensioned. You can run housing the whole length but the lever pull won't be as crisp, and it adds weight and looks stupid, and then you need zip ties or whatever to keep the housing running along the tubes.
My suggestion: Keep doing it like it is, do not run full length housing
>>906984
Are you fucking retarded or trolling?
>>906820
You need a tube for 700x42c tires (700x42c is another way of saying 622/42). Tubes come in ranges so it just needs that in the range, i.e. 700x35-45c would be good since 42 falls in that range of 35-45.
Also make sure to get the right style valve, presta or schrader
>>906771
If you want to run it for show and keep the lever tension anyhow don't remove the braze-ons just thread fitted lengths of tube into the spaces between them. The cable works against (all) the braze-ons
>>906984
For the benefit of the tire-enlarging community, things you should check when switching to a larger tire on your bike:
>rim compatibility (Sheldon Brown's chart)
>tube compatibility
>fork lateral clearance
>fork crown clearance
>front brake bridge clearance
>brake bridge clearance (if applicable)
>seat stay clearance
>chain stay clearance
>rack clearance (if applicable)
>fender clearance (if applicable)
>wheel true
>bottom bracket clearance (bonus)
>down tube clearance (bonus)
A manufacturer-recommended maximum tire size or the experiences of other users of the same model bicycle could be useful, but they don't excuse you from checking for yourself.
You could also go to an LBS and consult them, possibly to the point of trying on a wheel with a larger tire. Better safe than sorry.
>>906998
130 hub to 128, not 130 dropout to 128
>>907025
lol so you halved the useful life of your tire by being an idiot? That's cool.
are 1" threaded headset crown races interchangeable? I bought a used fork that already had a race on it. Do I NEED to put my race on it or will the one on it work fine?
>>907025

It's not Sheldon's fault you lack common sense
Any opinions on mavic open pro rims? Looking to build a wheelset and I was thinking about them. What are other good options?
Also, what's the difference between the old open pro and the open pro 2016? The older ones are like half the price on chain reaction.
Whats the average that a full suspension aluminum mountain bike should weigh?
I put a scratch in my carbon frame, is it dead? I can feel it a little when I rub my thumb over it. I didn't crash or hit anything, I just rubbed my other bike's studded tire on it by accident.
>>907107
Looks superficial to me
>>907107
Looks fine but maybe ask a professional's opinion. Seriously though I'd bet it's nothing. I have a carbon fork that looks like a beaver chewed the blade and the guys at the shop tell me its fine
>>907107
cover the scratch with car touch-up paint then apply a coat of carnauba wax
>>907077
no complaints here
>>907073
Strictly speaking, no, headset parts aren't actually interchangeable, but in practice there are only a handful of standard designs, so the odds that the race that came on your fork will match the headset currently on the frame are pretty good. Try it and see.
>>907077
Open Pros were the default choice for anyone wanting to build strong, reasonably light road wheels in the 90's and early 2000's, they lost a lot of their popularity as Velocity rims and good pre-built wheels came on the scene. Didn't help that there have been a consider number of reports of OP rims from the mid 2000's developing a rattle, probably a bit of excess material from the manufacturing process trapped inside the rim, which is not a safety hazard, but a definite annoyance (note that the number of complaints, while noteworthy, is still tiny compared to the total number of OP rims sold during that period, the odds of finding one of those defective rims are very, very small).
I've ridden extensively on Open Pros and Open4s (forerunner to the OP), they're strong, reliable rims.
Not sure if there's anything different about the 2016 model, google doesn't turn up anything either. I'd guess CRC just wants to clear older inventory out.
What's the deal with tension on pedals? The Look Keo Blades come in three different options (12Nm, 16 or 20) and I'm not sure on which ones to go for. Currently I'm running Look Keo Easys which, I think, run around an 8Nm tension and they are easy to get into.
If I buy the 16 will I be able to adjust the tension if they're too tight for me?
Thanks
>>907306
Can you stop being retarded?
That answer is no.
>>907311
Because asking about pedal tension is so retarded, how about you get off your fucking high horse. You're in a bike question thread.
>>907306
On most clipless pedals you can adjust the level of tension that the metal spring exerts on your cleats, but with a carbon leaf spring the tension is permanently fixed. If you're happy with 8Nm pedals, and aren't accidentally unclipping when you really mash on the pedals, then I would stick close to that setting and go for the 12Nm version.
>>906715
you could do that
or you could just put the wheel in the frame and not be a bitch because it's only 1mm difference on each side
Why do road cyclists not use hydration packs? is it an airflow thing?
>>907385
Comfort and necessity.
Because of suspension and shit mountain bikes often seem to have only 1 holder if any? And it's gonna get shaken around in there.
On a road bike 2 mounts is a given and with a little foresight you can usually find places to fill you bottles up on a ride.
>>907388
>On a road bike 2 mounts is a given and with a little foresight you can usually find places to fill you bottles up on a ride.
Although for most people your average ride will be less than the 100km or so it takes to drink two bottles
Why do so many LBSes only stock 1 or 2 brands? It kinda sucks a lot.
>>907398
Everything is way cheaper online anyways
>>907402
That makes sense, my plan is to test-ride a shitload and then buy online, it just sucks having to go around to a bunch of different shops to test ride.
>>907403
>being this ungrateful to your LBSes
Disappointed in you anon.
>>907406
So far the ones I've visited have been kinda shitty and arrogant to my new-to-road-biking ass, if I find one that clicks and doesn't have too much of a markup over online, that could totally change.
>>907413
that's exactly my plan. There's a local maintenance co-op that has classes and basically charges just a tool-use fee (plus some for parts) while having competent mechanics on site to help out
>>907397
I'm in Australia too and I usually go by 1:50km. Naturally this can change depending on pace but it's a pretty good rule of thumb for me
>>907398
There would be no point in them stocking several bikes that are all effectively the same.
>>907423
>There would be no point in them stocking several bikes that are all effectively the same.
That makes sense for the shop but is kinda annoying for the customer, I guess.
I wear corrective glasses. Contacts suck--massive blink reflex. I've seen corrective wraparounds for cycling, but on the other hand poorfag.
Any other slightly-blind cyclists have any advice?
>>907398
>>907424
The reason that most shops only stock a handful of brands is because the big companies that offer full product lines (Giant, Trek, 'Dale) require shops to place a minimal annual order to maintain their dealer status - small shops simply don't have the physical space or sales volume to carry more than one big brand, and for bigger operations, the wholesale brands offer incentives (help with marketing, training, volume discounts, and limits on the number of shops in a given region that can sell that brand) that encourage brand exclusivity.
>>907431
Likewise I'm too cheap to buy prescription cycling glasses (and have read too many bad things about Zenni), I just wear my regular glasses and a cap to keep the sun out of my eyes.
>>907398
>>907469
Listen to this person w/r/t brands in bicycle shops. They have the correct answer.
>>907431
I have had a lot of luck with wearing a cycling cap and my prescription glasses as well.
>>907421
Bicycle co-ops are a great way to learn how to work on your own bicycle. I've volunteered and visited a few in the western United States. If you are willing to work your way past some of the rough edges, you can learn a lot at your local co-op. I learned all of my mechanical skills at my local co-op, which in turn lead to me getting a job as a mechanic.

Does anyone have experience mounting fender + rack on the same eyelet?
I looked up online and most of the responses seem to be "put the fender mount on the outside" which is all fine and dandy except my bike has disks, so the rank has the different mounts which means you couldn't do that.
Should I just get longer bolts and put the fender mount on the inside, or find a different solution entirely?
>>907505
I've done it both ways - fender stays to the outside is stronger in theory, but if you do run them inside you're only moving the rack stays outwards about 3mm, it's small enough that it doesn't matter in practice.
Changing a flat: How do I get my wheel off? Pic related. Apparently I need to release the breaks but the internet is doing a terrible job of explaining what I'm supposed to do. Is it the thing on the bottom, right above the wheel, which I would need a wrench to get off? Or is it the thing at the top, which I'm not really sure how to get off or release?
>>907616
also I'm not sure why it's flat. I just got the bike used, tire was fine when I picked it up and rode it a bit just to test it, then let it sit for a week because I didn't have time to ride it. Was going to go riding now but it's flat. The little cap thing for the wheel valve is missing, could that be it? I know for car tires those don't seem to be crucial, are they more important for bike tires? Or is it likely an actual flat where I'd need another tire/tube? I gave the tire a quick look-over but didn't see anything.
>>907616
You have cantilever brakes, so the easiest way to open them for wheel removal will be to unhook the transverse cable. See pic, one of your brake arms will have a slot where the end of the transverse cable attaches, slide it out of there.
>>907619
Take the tire and tube off the wheel, put air in the tube and listen/feel for leaks. Also, check the interior of the tire for thorns or something that may have poked through.
>>907621
great, that worked thank you!
So I bought this vintage jap road bike a couple months ago. Some of the parts are pretty old and when I ride it, it makes a noise. I'm looking to buy a new cassette and chain (maybe a new crankset and pedals too?). How do I size the crankset and chain? It's a 7 speed, 5 cogs on the cassette (I think) and 2 cogs on the crankset. Can I just buy 7 speed chain and shimano 5 speed cassette and it will be fine?
Also another question, when I took my wheels off to replace the tires and put them back on, I think I fucked up the de-raileur reinstallation, pic related.
>>907797
>How do I size the crankset and chain
Meant to say cassette and chain.
Also another pic.
tired of using this shitty piece of paper clip for my light
does anyone have any ideas for something better i could find around the house or know where to get another clip thing?
>>907797
>>907798
Alright son, few things:
This is you right now: https://www.youtube.com/watch?v=seP2DPqd0o8&t=71s
It's a 10-speed, not a 7 speed. Multiply the rear cogs and the front chainrings, don't add them.
Next, you can't throw parts at the problem if you don't know what the problem is. Where is the noise coming from? What sort of noise is it?

>Can I just buy 7 speed chain and shimano 5 speed cassette and it will be fine?
Yes.
>I think I fucked up the de-raileur reinstallation
You sure did. The bolt on the derailer hanger is supposed to go inside the dropout, you've mistakenly bolted it through the hole where racks/fenders are supposed to mount. See diagram.
>How do I size the cassette and chain.
Here's a good explanation about chain length:
http://sheldonbrown.com/derailer-adjustment.html#chain
>>907797
You want a 5 speed freewheel not cassette. Make sure you don't have some weird niche threading size on your hub too! Also a 5 speed chain, not 7. Your bike is a 10-speed, but if you were to ask for a "10 speed chain" they would give you one designed for modern 10 speed cassettes
>>907797
Did you lube the chain? What is wrong with your crankset, pedals and rear derailleur?
Your bike will need a freewheel, not a cassette. You could even see if you have the space to install a 6 speed freewheel though, if you wanted. When you are looking at chains, remember the number of speeds corresponds to the number of rear cogs only, not the chainrings.
I doubt you'll have to worry about the freewheel threading, a japanese bike is probably pretty standardized.
>>908013
Science.
I've just been lurking craigslist for a 200-350 dollar road/touring bike. Not a lot of selection.
Anything I should look out for?
Anything I should avoid such as certain bicycle names?
Any other websites where I can find some local bikes?
>>908042
1. Look at Kijiji if you're in Canada, also Ebay (odds are very low but you never know what will be listed locally)
2. Stick to bikes that you can google and find results on, avoid stuff that's unlisted because those are probably crappy Walmart or a department store bikes.
3. If you're in a rural area, trying to find a used bike online simply may not be an option.
>>908044
I am a Burger. Tried Ebay already, but no luck.
Should I save up more and buy a steel frame bicycle? Feelsbad being a poorfaggot, I'll have to sell even more of my shit.
>>908042
just for curiosity, post your local CL url over in /bbg
things to look out for:
-idiots trying to hawk bikes with bent forks
-one-piece cranks on non-bmx bikes
-stem shifters
-brakesets with extension levers aka "turkey levers" aka "suicide levers"
-frames with removable "claw" derailer hangers
-surface rust on rims/handlebars/stems (steel boat-anchor components)
-no seat-tube decal detailing frameset material
-slammed seatposts (sometimes denotes a stuch seatpost)
>>908046
>post your local CL url over in /bbg

Not a lot of selection. There's that black Bianchi, but I don't know what the model is.
I also had my eye on that Univega Viva touring bike, especially since it's a steel frame.
What do you think?
I think it'd be smart to just wait for more selection.
>>908045

>>908083
oshit
I thought I was in BBG. My miss steak.
>>908056
Fairly rare, dependent upon rough treatment. Al tolerates bending forces less well than steel; frames with manufacturing defects tend to crack at welds. See also: stress corrosion in Al aircraft structures.
>>908046
Curious here. What's the hate with removable derailleur hangers? I have a 1981 bike with one of those and apart from the rear wheel being more painful than usual to install perfectly straight it hasn't given me any problems. Frame is nothing special but my area's a wasteland when it comes to nice used bikes.
>>908154
Not that guy, and I actually agree with you, but from the 1960's onwards most high quality frames came with integrated der. hangers, by the 80's only cheap frames used bolt-on hangers, so the presence of a bolt-on hanger on an old bike is a pretty simple way to make a quick judgement about overall quality.
People recommend thru axles for front discs keeping it from ejecting the wheels, what about rear wheels?
>>908264
Generally, the rear wheel will skid before there is enough braking force to eject a QR-fastened wheel, but for most MTBs, the most common rear standard is a 142x12mm rear thru-axle. The industry will be quickly migrating to 148x12mm in a few years. Thru-axles are great and highly superior to QRs, especially for rear-suspended bikes.
>>908266
Totally slipped my mind that rear wheels can skid. Thanks.
I have money and 50km track nearby for road bikes. I've decided to start cycling on top of lifting. Lifting was pretty easy to get into, /fit/ had a sticky which summarized anything and everything but I haven't been able to find one for bikes around here yet.
Confused as fuck about what a derailleur is and was wondering if there is a sort of starting bike general here?
Please and thanks
>>908288
What country are you from and what realistically is your budget?
>>908288
Watch GCN on youtube
>>908288
Just make sure you don't get a mountain bike
>>908294
Australia, Sydney. Budget of 1500 total, mind you I don't own anything related to biking, not even a helmet (current single gear bike gets me around the corner for milk and bread). 5'7"
>>908295
Thanks mate
>>908297
I have a single gear bike for local commutes now. I don't think I'll accidentally end up with a mountain bike though I wouldn't be against buying one for bush riding later on
>>908288
>derailleur
the mech that moves the chain to the desired gear. usually two, one above the crank and one next to the rear wheel; but sometimes only one. single speed bikes have none. some bikes with no deraillers will have an internally geared rear hub, though.
>>908299
Wow imagine a fine for riding around the corner for milk and bread...
I recently bought an Orbea Mx30, love the frame but shitty components.
So i want to upgrade it:
-Front wheel suspension: it comes from factory with a coil sr suntour xcr and i would change that for a decent air rocksocx, ideal model is rockshox recon gold rl but i dont think ill get it where i live, so any decent air suspension is fine
-Pedals: It comes with fucking plastic ones
-Crank: to a single-speed one so it will have a 1x9 speed
-Rear derailleur: it comes with a shimano alivio, im kinda fine with it cause they´re more than i expected but will definitely be changing it for one with a longer arm(derailleur cage?) and fitting also a chain tensioner
Thoughts? Please recommend me somethinng, i need /n/'s wisdom
>>908313
No local cop has ever stopped to enforce this silly rule. What's the data on bike helmets show? Do they make a difference?

Sorry mate didn't know
I am looking for new tires for my bike >>>905591. I don't want to spend a lot on it because I don't ride a lot and I just want to get the bike in good running condition. I was thinking about these Schwalbe Lugano beige tires. Do you guys know if they are any good? And does the beige matches with the bike?
Would like some advise. Thanks in advance /n/!
>>908454
What size are your rims? If they are 27" I've really liked the Panaracer Pasela. If 700 plenty of budget options out there like the Continental Ultra Sport II. Nashbar has them for $16/each right now. Don't go too cheap, the shitty ones from China have QC issues and the diameters are always a little out of spec.
>>908454
Schwalbe tires are "meh." Have a look at Conti or Michelin
Are there any bikes that function decently for both off-road and on road cycling?
>>908534
cyclocross bikes
>>908534
Tires are what determine off-road and on-road
Unless you're some ski-lift taking fat MTB hamplanet, you'd be fine with a cross bike for actual transportation, like the other guy said
>>908540
No problems as long as you have strong wheels.
>>908538
whats wrong with mountain bikes though
>>908566
Nothing. Having suspension can be really nice for navigating really shit terrain, but it causes a jump in price and requires a little extra maintenance. However if "off-road" just means a bit of dirt and gravel in between longer stretches of road, you're better off with a road bike with 700Cx28 or 32 tires, although 650Bx42 is an interesting choice if you're more off the road than on. CX bikes are nice because they have a bit more ground clearance.
>>908465
>>908508
Thanks for the help. There is a 700 tire on it right know so I believe it will a 700. I will take those conti tires into consideration. Do they have any kind of noticeable puncture protection?
And can someone give me some advice on innertubes? What are some decent ones? Does it matter what innertube I chose if I want to ride on 25mm wide tires??
Thank you!
>>908589
Any decent innertube recommendations? I am pretty new to biking and I don't know what tot look for in an innertube. Don't want it to be expensive.
>>908654
I've had great luck with Bontrager tubes.
>>908654
>>908589
in my experience, tubes are pretty inconsequential. i'm running a cheap brand i'd never heard of from Amazon right now. just make sure
>your wheel size is right and
>your tire's width is within the range listed on the box.
>you get the valve type that matches the hole drilled in your wheel i.e. what type is on the tube you're replacing; schrader is the one also used by cars. presta is the thinner bike only one
simples.
Do I need treads to ride on hard dirt and gravel? Any recommendations for tires riding 80% asphalt 20% gravel? One set or two sets of tires to change when I want to ride a certain road surface? I also have a tubeless ready rim.
Wouldnt mind changing tires on clinchers but having to change tubeless tires everytime I want to ride a different surface seems dumb.
>>908692
Slicks or semislicks are just fine on hardpack. Knobblies are for loose and muddy.
>>908654
most butyl tubes are made by cheng shin or kenda, and rebranded as whatever. they're decent, although they don't exactly have the tightest manufacturing tolerances. some companies make their own, like schwalbe and conti. they have tighter QC, but no real performance advantages with respect to punctures or rolling resistance.
latex is a different game altogether, but honestly if I were looking to minimize rolling resistance with clinchers I'd just go tubeless.
>>908692
Schwalbes marathon tubbies. Almoation is best
>>908704
Swapping to latex tubes is probably a lot simpler for most people.
Also while the best tubeless road tyre (pro One tubeless, possibly) is very close, apparently the GP4kS2 with latex tubes is very slightly less rolling resistance.
>>908692
Depends a lot on the gravel, but provided it's relatively tame (and flat) then you shouldn't have a problem on slicks.
>>908692
Echoing what others have said, slicks are fine on gravel as long as it's dry and not overly loose. Also, the wider the tire, the more comfortable and stable it'll be, I like the Challenge Parigi-Roubaix (28mm) as a fantastic fast road + gravel tire, the Soma C-Line (38mm) if you're a heavier rider or going to carry cargo, and Panaracer Paselas if you're looking for something less expensive but still nice to ride.
Currently riding a '06 Specialized Dolce 3x8, sora/tiagra mix. Alex DA16 rims.
Should my priority be upgrading my gruppo to 11 speed or getting a new wheelset?
>>909072
Do you feel like you need 2x11 gears?
I'd still probably say a new groupset though, since 8 speed Sora is thumb shifters. 52/42/30 x 11-23 has a pretty similar spread and tightness to 52/36 x 11-25, if you don't mind triple shifting the front. You may actually shift a triple front less depending on your speed.
And I'd upgrade rubber before wheels.
I have an old 1981 model year ten speed with Shimano 600 downtube shifters and rear derailleur and a 5 speed freewheel that is starting to get worn out.
Would it be a better idea to get a 6 speed freewheel and respace the frame to make it fit or get a HG 5-speed freewheel, if they even exist?
>>909072
If you have Sora shifters, at least upgrade to Claris shifters so you can have real STI instead of that terrible thumb shifter. Going to 11sp will almost certainly require you to get a new rear wheel, as 11sp Shimano cassettes are different than 8-10sp. So, it would be best for you to save to get 11sp + new wheelset at once.
>>909077
Shimano triples are 50/39/30 for some weird reason.
>>909084
Depending on your current hub you may only be able to run a 5-speed freewheel, get some calipers and measure whether it's 120 or 126mm wide, upgrading to 6- or 7- might require a different wheel.
>>909084
Spreading your frame to accept 6sp is the best best, although you may as well go to 7sp when you do that. Either way there's a steady supply of 6sp and 7sp cassettes.
If you don't feel like spreading the frame you could look into getting a Suntour Ultra 6 cassette with a 9sp chain.
>>909077
>>909086
Am I the only one that actually likes that old thumb-shift mech? For some reason I thought that shit was so cool back when I bough my first road bike (was 15 at the time). Felt like I was driving a stick shift or something mechanically organic like that. My current ultegra, rival, 105 gruppos are better, sure. But goddamn that thumb toggle was soo different!
Makes me crave campy for the same reason.
The owner at my LBS told me I should buy Gatorskins instead of GP4000S II's because they're way more resistant to flats, which I think is true. I had probably 5 flats this year due to glass and other crap on the roads here.
Apparently the GP 4-Season is just about as resistant to flats as the Gatorskins but ride nicer? They're more money though... Should I just go with the Gatorskins?
>>909086
>Shimano triples are 50/39/30 for some weird reason.
I doubt it if it's 8 speed Sora.
>>909106
Gatorskins have really stiff sidewalls, if you're a heavy rider (200+ pounds) they roll nicely, if not they feel overinflated all the time. The 4Sea is right inbetween the Gator and 4000S in terms of both protection and ride quality, a better choice if you're lighter.
>>909114
Claris shifters would be compatible, so would a claris FD.
>>909106
I had Kontenders, Luganos, Gatorskins, never tried GPs but Gatorskins worked the best for me puncture protection wise. I've since ridden on gators exclusively for 3 years now. Great if you want puncture protection, but get prepared for a very unforgiving harsh ride. The only time I punctured was when a pinky width piece of glass lodged itself into the tire.
>>909116
From what I know, Shimano triple STI shifters (aside from 8sp Sora) have to be mated with specific Shimano 50/39/30 chainsets, due to how they index and how the ramps and pins work to assist the shift.
Mum got me a saddlebag and one of those toptube storage thingies for my bike :3
Commuter bike btw before you start going
>having anything on your crabon bike
Got some money too, will get some tyres because the current ones are fucking shit. Will probably get some Schwalbe marathons.
does anyone have any experience with having action cameras always recording on a ride? or using the video as evidence to show that you arent at fault for anything?
I feel as if I want one for my own protection, last year a car cut me off at a nearly reckless speed and a few months ago another car got really close and I had about 4 inches between him and the parked cars. and just yesterday a car lost control 50 feet ahead of me and jammed itself into a place that I often wait on red lights for.
I can figure out which cameras are good myself I just want an idea about the practicality of them.
>>909165
Most people with cameras turn into complete wankers, cycle like shit, constantly act like a victim and would rather get run over than get out the way.
I'd be careful m8, might corrupt you.
>>909110
I'm 160lbs. I'll try the 4-Seasons.
>>909175
Not really. They're a bit of a period piece since the UCI banned them.

>>909200
Yes, that's a fucking steal
>>909205

It's shit
>>909194
Not really worth what most sell them at, you can put a smaller front wheel on your bike if you have a fix, then you'll realize how stupid you look
>>907799
How often do you take that light off of your bike? Could you just use a ziptie?
What issues or things am i going to have to watch out for when switching to a smaller tire?
Ive been busting around on my commuter for about a year (mid 2000s MTB with slicks), and i ride pretty aggressively. i decided id like to build a road bike a few months ago, and it looks like it will be totally complete by spring. The tires that i got for it, some Conti 4 Seasons, are only 23mm wide, this is by far the skinniest tire i've ever ridden, what should i watch out for when i get on for the first time?
Basically, as far as tires go, how is the handling/my behavior going to have to change when i get this road bike finished?
>>909208
Xenon is fine and I'd buy that bike for $250 in a heartbeat.
>>909215
You'll have a harsher ride and less traction (presuming you'll be running higher pressure on the Conti 4S and you do on the slicks), but more responsive handling. The bike may feel twitchy at first.
How often is too often to change your pedals??
I always thought of pedals as a set and forget sort of thing, is it a bad idea to be changing my pedals over about twice a week?? are the threads in the pedal and in the crank going to put up with it?
>>909225
As long as you are careful to not fuck up the threads, and don't over torque them, it's okay to change your pedals, theoretically, forever.
In all practice, it is unnecessary wear and one of these days you're likely to mess it up.
Pedals usually don't need to be replaced unless you take them off and can feel the spindle moving irregularly as you spin it.
If you really need to take your pedals on and off often, consider getting some MKS ezy pedals.
>>909228
No, not forever. Screws and bolts have finite lifetimes when reused. It's unlikely that you'd reach that point though, but changing pedals twice a week sounds retarded.
>>909234
look asswipe, i said theoretically.
Yes, in reality, there's friction involved, and the aluminium cranks and threads are most vulnerable to those forces.
If you were a pro pedal installer and always entered at a perpendicular angle, with perfect alignment and engagement, and greased the threads, and used a perfect pneumatic driver with a torque limiting option, yes you'd be fine, forever.
>>909234
>>909236
Calm down /n/egros and merry xmas, both your points make perfect sense to me, honestly
those quick release pedals are nifty, never knew they existed.
I just ordered ball bearing and plan on rebuilding a set of shimanos, it is annoying as shit to set the balls in place to slide the sleeve on them.
>>909236
>look asswipe, i said theoretically.
But that's not theoretically true.
>Yes, in reality, there's friction involved, and the aluminium cranks and threads are most vulnerable to those forces.
Grease can be used to minimize friction
>If you were a pro pedal installer and always entered at a perpendicular angle, with perfect alignment and engagement, and greased the threads, and used a perfect pneumatic driver with a torque limiting option, yes you'd be fine, forever.
No you wouldn't.
>>909238
my 2 cents is that he is right, if you were to say "forever" as the rule of infinity is concerned, you would slowly over decades and centuries of torquing down the pedals. The steel would eventually turn to dust lol...
CALM DOWN YOU TWO fuck. everything is kool. Fucking cycling you know. relax my fellow peddlers
>>909240
It has to do with bolt/thread elongation and fatigue. Not friction, not dust. This is common engineering knowledge. It's why for all critical structures, say a bridge, they will replace a bolt if they remove one, rather than reusing the old one.
>>909243
You are getting into the hypothetical that there is a man out there removing and installing pedals all day long.
I see your point now, some pedals do use lighter alloys in pedal design, but for all intensive purposes you should be able to remove and install a set of pedals several dozen times. which should outlast the bearings
Unlike my case, I had a set of bearings go bad after 1k miles, the pedal set started to make a clicking noise...sucks
>>909243
1 more question, how many times do you think a pedal could be removed and installed b4 you need to replace the bolt or crank...just curious for your opinion.
my guess would be a very long time. the stress on pedals is les than the bridge you gave example of
I ordered one today. Ill give it a few trial rides. I'm kind of a pushover and I always avoid confrontation, hopefully it will carry over.
if anything I can use it for when I'm riding trails and renting DH bikes at bike parks in the summer.
>>909246
>You are getting into the hypothetical that there is a man out there removing and installing pedals all day long.
The guy literally said once or twice a week. Literally. I am quoting him. And you said something would be theoretically true, which it isn't.
>I see your point now, some pedals do use lighter alloys in pedal design
This is for plain old steel as well.
>but for all intensive purposes you should be able to remove and install a set of pedals several dozen times.
Based on the figure 1 to 2 times a week, that's 4 to 9 dozen times a year.
>>909247
> the stress on pedals is les than the bridge you gave example of
And the bridge uses bigger bolts to handle the increased stress. The issue with constantly installing pedals is risk of cross threading, but it is not unheard of for someone to pull the threads out when torquing the pedals to normal specs. I can not give you a figure, because pedals usually aren't changed enough for this to be an issue. The point is that there is wear and fatigue on the threads if you keep doing it repeatedly, and it has happened where fatigue caused the threads to fail.
>>909246
ALL INTENTS AND PURPOSES
>>909243
it's called risk management dummy.
it's not the bolt gets tired after being removed once, and that they can't engineer a bolt system that would be less affected by fatigue, it's that with all the uncontrollable variables in construction, it's simply easier to use a new bolt.
Again, unless they want to guarantee the perfect scenario of bolt removal and installing, it's less risky and more cost effective to use a new one.
>>909257
And the point is thread fatigue from installation is a real thing, and you can not "theoretically" re-use threads forever. I'm not saying you should replaces your cranks and pedals every time you change something.
>>909260
yeah, you've clearly backed yourself into a corner and don't understand what you're arguing.
>>909147
What's the question
I realized I need to start cleaning and taking care of my bike better, so I'm gonna start regularly lubing the chain.
Any recs for a good chain cleaner though so I can scrub off all the dirt and grease? I have a brush and all that jazz, just don't know what I should use to clean it first.
>>909404
Simple Green for degreasing, standard dish soap for general cleaning. For cleaning gumwall tires, I've found that 409 works pretty well.
>>909200

>>909412
Anon says tap that shit, son
Hey /n/ I need a good brake set for my new build (KHS aero track curved seat post) I would like the levers and calipers to be silver and simple, not like the super long levers just average non flashy ones, I would like some suggestions

Hey y'all
I'd love some whilst recommendations for my next single speed build. 700c 15 rim
Price max : 400
Does frame flex actually exist? I've never experienced any flex from any bike, apart from wheel flex. I'm a 5'4 manlet, could it be because I'm light? Even walmart bikes don't feel like they flex.
>>909857
Even as a 75 kg manlet I'm frustrated because all the bikes seem to flex noticeably. Try putting some torque through the pedals. Say trackstanding with big gear in uphill. Not so stiff even with my xt cranks. And doing stoppies with old xc bike with quick release axle - eeeeww. But still I think frame flex isn't a huge problem with road bikes unless you race hard.
On 650b conversions, does one use 650b fenders or 700c fenders ?
>>909857
>>909872
Frame flex is definitely a thing, and more body mass increases the chance you'll notice it. I'm a lightweight at 155lbs but have been able to flex plenty of frames - pic related was probably the most noticeably flexible frame I've ever owned, I could definitely feel the rear end wiggle when I sprinted out of the saddle. Most of the time though I only notice frame flex if the bike equpped with friction shifters - when the rear end flexes the distance between the shifters and derailer tends to pull the cable (and therefore the shift lever) out of position very gradually over the course of a ride.
>>910013
Either is fine as long as the fenders are wide enough for the tires. The difference in circumference measured around the outside of 700 and 650 tires is less than 4cm, and that's within the adjustment range of most fenders.
Looking to buy tights and a jersey. Not sure how sizes work for pants/tights. Got a 33" inseam and a 29" waist. Should I go for a small or a medium? I feel like medium will be too wide but small might be too short.
Two months in, I just noticed that the spokes on my new bike's rear wheel have been coming loose, to the point where some of the nipples are no longer engaged.
No impacts or falls that I can remember. No serious curb hopping, either. Just hauling my fat ass for a few hundred miles. I haven't modified the wheel other than changing the tire.
The bike is under warranty and I plan to take it in to have it repaired, but I want to get this in context before contacting the shop.
>is it reasonable for spokes to come loose this way on a new bike? (break-in/manufacturing issues/etc..)
>how often should one have to deal with the spokes in a properly functioning bike?
>I lock up the bike by looping a u-lock around the seat tube and rear wheel, is it bad for the spokes?
>could this spoke issue be the result of changing to tires requiring higher pressure?
>>910164
what wheelset do you have?
if you cant answer that, what bike do you have?
whats your weight?
spokes should not come loose all that easy.
I ride pretty damn hard and only have to true my wheels once or twice a year.
>>910150
really depends on brand.
buy two sizes thru amazon or someplace similar, return the one that doesnt fit.
I'd recommend trying Pearl Izumi shorts/bibs. They're comfortable and hold up well.
>>910150
every brand fits differently, and most brands have different lines with different fits. for instance, pearl izumi tends to be quite, uh, generously sized, while pearl izumi elite has a tighter fit.
>>910164
unless you are a tremendously fat fuck, that shouldn't be happening. however most new bikes ship with shit wheels so yeah.
hey...so after doing the brakes on my rolling cage I have 3/4 of a jar of CRC caliper grease lying around.
Humor me. Do you think it could possibly work out decently as a headset grease?
It is all I have on hand and I don't want to buy a tub of normal grease that I'm going to use barely any out off...
Also posted this in bbg but that thread seems a bit inactive. This seems like a good deal but the lack of actual pics makes me kinda worried. If I can get real pics would it be a good buy?
http://sfbay.craigslist.org/scz/bik/5379479137
any /n/ approved bike racks for cars?
>>910150
I don't know what my inseam is, but my waist is the same as yours.
I can tell you I just followed the charts on the stuff I bought, despite numerous reviews on wiggle saying "size up"
So that means size S in castelli, which was fine, and size S in dhb asv stuff which was also fine.
The only thing that actually came in too small was a size S merino undershirt, which has much less stretch than lycra. Had to swap that for the M.
>>910263
Wat
>>910263
we don't deal with cars around here
we can recommend you a bike rack for your train though
>>910263
What type of rack are you looking for? Roof rack? Strap to your trunk? Hitch-mount rack - top tube or tray style?
The best rack money can buy is a hitch-mount tray rack from 1upUSA.
There are a lot of other good options are out there as well, depending on what kind of car you have and what your budget is.
>>910166
The rim is Shining MT-20 (http://www.shining-cycle.com/en/product/showinfo-176.html) so it's basically no-name Taiwanshit. It takes 36 spokes.
The hub is Formula, which is no-name Chinashit.
The bike itself is Kona Dew.
My weight is 250lbs.
All in all, I'd expect all this to hold up even if it's no-name Sinosphere shit, but no luck this time.
>>910392
Cheap wheelset + heavyweight rider is a bad combination.
Hey /n/, can anyone tell me the name of the little crimp on bits at the end of brake cables real quick?

Cable crimp.
what's the revzilla of bicycles? small threshold for free shipping, no taxes, under msrp, etc

Now now, anon.
For the Church of the Rusty Crank to grow its flock, we must be willing to overlook past transgressions.
>>910392
Presuming you don't have dick breaks, I'd recommend something along the lines of a Fulcrum Racing 7 LG CX wheelset, which will work with your 8sp cassette with a 1.85mm spacer.
It's really annoying that even expensive racing bikes come with shit wheels.
>>910510
No shoe cover will help if the rain is strong enough and you ride long enough
Just get the sizing right and don't worry too much about the brand
>>910510
BBB products are actually really good. It's not as popular but everything is priced right and functions well.
How worth it is it to go out of my way to test ride a bike? Since shops basically only stock one brand, is it worth it to travel like 30-50 miles to test ride a bike that I might like a lot better that isn't carried in one of the super-local shops?
Update to >>910244
got the guy to post pictures, http://sfbay.craigslist.org/scz/bik/5379479137.html
look like a good deal?
>>910565
Depends on how much selection you can look at locally and how specific your needs are - if you're looking for a basic bike you won't find as much difference between what different brands/shop offer as you would if looking for a high-end road bike with 'just right' geometry.
>>910606
It's an okay deal, just make sure that the chain doesn't skip (new chain on an old cassette can do this if the cassette has lots of wear) and the wheels are still true.
Would it be dangerous to clean bike parts in my basement with chemicals like acetone? I want to clean summer bike which I have neglected maintenance. I don't want to explode or die a painful death.
>>910614
Really depends on what you're using and what the ventilation through your basement is like: Using anything with toxic or flammable fumes in a confined space is a bad idea. Citrus degreaser is fine for indoor use, acetone is borderline (not a problem in small amounts), MEK, gasoline, kerosene, etc. are not.
>>910614
Just use the bathtub.
>>910606
not bad for the bay area. I was laughing a bit at the gearing but then I remembered the Seven Hells
>>910613
Basically, I'm looking at endurance-geometry bikes in the $1K-$1500 range, and the Felt Z85 has really caught my eye, both in terms of spec/price, but also because I think it's a pretty bike, but the nearest store that stocks them is a fair distance away.
>>910696
I would recommend the Fuji Roubaix with a set of Ultegra wheels. I rode the z85 and think the roubaix was the better buy for weight/price.
Are there no shimano hydraulic disc sti 3x10 shifters?
>>910731
As far as I know only SRAM makes road disc brake brifters
>>909412
There are plebs who would buy the STIs for that much.
So I got this from my local co-op for $60 for a new build. How fucked am I /n/?
>>910772
Another pic.
Also small amounts of surface rust on the frame. Any tips for treating it or do I just say fuck it and leave it as is?
>>910772
>campy hoods on shimano levers
My keks
>>910722
I don't see the Roubaix on Fujis website. Did they change its name?
>>910773
Just spray it with WD-40 and may try to brush it or use steelwool and slowly polish it out of the Screw... or just replace the Screw. As long as you keep a layer of Grease over Rust (Like WD-40, Wax or something else) the Rust itself wont grow anymore, due its lack of Oxygen (Which is a Lazyfucksolution)
>>910788
Never mind I'm dumb.
>>910733
Shimano has been making them for years now, in mechanical and Di2 flavors.

Can't even find the new Tiagra triple parts even though they're supposed to exist. Just compact with 11-32.
>>910773
best steel
to my mind, your issues start with wheels. this is a good opportunity to get some modern integrated levers and build up the drivetrain around a modernish 9-11 speed hub and cassette. getting prebuilt wheels like that will prob be 700c. so far so good. but there's like a 50/50 chance that the frame is for 27" wheels, in which case you'll have to replace the brakes for longer reach models. or you could opt for 27s with a modern hub but that will be a custom/expensive job, i'm assuming. harder to find, anyhow.
you could just put used wheels with the 6 or 7 cogs that your existing levers index to, probably find them at said coop for cheap and the rest of the kit there for a good price but that's the "aim low" option and you may end up upgrading over time anyway. in the long run it'd be easier on you and cooler to just aim high, if you've got the cash.
that's one of the realest of steel frames, aim high if you can. you'll have a cool bike either way, i reckon. cool color, too.
>>910830
Yea I was really at a loss for what to do. This is my build for 2016 so I'll probably aim low and work from there.
I checked and the frame is for 27". Would it be better to get a 700c fork or would the headtube angle not work as well with 700?
I know a guys that could get me a full dura ace groupset for $350 and he'd probably throw in a pair of really nice mavic wheels but I'm still not sure how much I want to sink into this build.
Where could I find more information on the bike? I'd like to know more about the frame before I start throwing money at it
>>910851
Don't take this the wrong way, but if you require a third party source to tell you it's a good frame, what good is a dura ace groupset and fancy wheels to you?
>>906715
Would a 56tt 56st bridgestone frame fit a 5'8" guy with 30.5" inseam?
I tried to balance affordability with performance/reviews. Is this alright for a first set? Also, it's not crazy to wear a jersey as a baselayer, right? And can anyone recommend some gloves? Or at least a pair of gloves decent enough last and thin enough to be worn over liners.
>>910851
>I checked and the frame is for 27". Would it be better to get a 700c fork or would the headtube angle not work as well with 700?
i don't have a qualified answer, but i'd be wary of monkeying with the geo at all. usually people just get brakes with longer arms. i know tektro makes some. i mean maybe your brakes would actually reach, but it doesn't look like it.
>Where could I find more information on the bike? I'd like to know more about the frame before I start throwing money at it
there's a guy that was in the industry for years that scanned his collection of mfr. yearly catalogs, including a bunch for Miyata. i found him via google when i got my 87 model 312 (pic related.) Miyata's rep is that, of their era, they made the finest frames in all of japan and they even forged their own steel. but how that compares to Tange (they did use Tange 2 before they built their own mill, but yours should be Miyata steel) Columbus or Reynolds etc i don't really know. Triple butted Miyata steel was world class but the industry moved to alu and crabon for road bikes not long after their triple butted frames were introduced in '87. that's all i know.
i love my Miyata, but i got it fully stock so i didn't bother with fancy upgrades since i have an alu "fast bike" already. Miyata is my daily driver tho.

I want to turn this used carbon road bike into a commuter and have a few questions.
Is there a way to fit racks to a bike without mount holes?
Braking from the hoods seems really bad, is this standard to 5700 105 or have I been spoiled by hydraulic discs?
Would upgrading the calipers to something like ultegra improve the brakes a lot?
>>910880
1. Putting racks on carbon frames is a bad idea unless they're designed with rack mounting in mind, stick with saddle/handlebar bags.
2. Hard to say about the brakes, could be something technical (hardened/incompatible brake pads, some kind of setup error) or just your perception if you're not used to them yet.
>>910856
borderline too big for you in both dimensions, find something 53-54
>>910851
Most of the questions have been answered already, but as for frame geometry, as long as you're converting both front and rear wheels to 700c at the same time, nothing changes except that your BB gets about 4mm closer to the ground
Is this a good buy for a winter commuter?

Alright lads.
I hate the ratios on my cassette. I know it's a cheap hybrid (not a BSO) but they're really shit. I'll be going up a hill, change down and suddenly I lose all my momentum and my legs are spinning like mad, really annoying.
I want to get a new cassette. Is there anything I need to worry about or do I just get a 7 speed cassette, slap it on, and index my gears?
What tools do I need? Cassette remover+chain whip? Is that it?
>>910950
You might not even have to index your gears. But, yes, chain whip and locking ring is all you need. It's pretty simple.
Can you actually get a 7 speed cassette with a tighter spread though?
>>910951
Yes, pic related on the left is my current one, as you can see the low end is ridiculous, the one on the right for example looks like it would be better.
Current one is 12-32 and the one on the right is 11-28, will I have to get a different sort of chain due to the difference? I'm planning on getting new chain anyway, but do I just need to get another 7 speed chain?
>>910954
Yes
