Scrod:

My friend's V-brakes on her bike have been needing constant readjustment (re-centering). I feel like the brakes shouldn't have to be adjusted so frequently. Do you have any ideas on what the problem might be? (I don't have specific details, but I can try to get them for you).

Thanks!

Scrodzilla 03-21-12 06:40 PM

It's hard to say without seeing the bike. Some V brakes just suck.

Do you have any suggestions as to things I should try to adjust? Or is it just something a mechanic he knows what he's doing should look at?

Scrodzilla 03-21-12 06:48 PM

The springs may be starting to crap out. If you remove the brake arms from the posts, there should be three holes in which the spring can be inserted (typically, it's in the middle hole). Try putting it in the bottom hole, causing the brakes to have a little more 'snap' and usually hold side to side adjustment better.

Sounds like a plan. Thanks for the help!

Hi, for the next thirty seconds pretend i'm scrod:
also clean the **** out of the brake canti stud posts, and clean the insides of the brake arm mounts... even a speck of dirt in there will put a ton more tension on the spring. if the springs have set screws to adjust tension, try putting them at half tension and bending the spring arms that attach at the top of the canti arms slightly between your thumb and forefinger. also, get new pads so there is as much cable as possible between the two.

V brakes are so much easier to work on than actual cantis.

Scrod I went out for a ride last night and inspecting the bike I saw that 2 chainring bolts were missing, both ends of the bolts. Is this common? The crank in question is a Sugino RD2, thankfully I had an Omnium laying around so I changed it :)

Also can you recommend me good replacement chainring bolts?

Scrodzilla 03-22-12 06:55 AM

It's not exactly common but you need to check your bolts pretty regularly because they do loosen up. It helps to put a small drop of blue Loctite on them before installing. Any steel bolts made for a single ring will do.

Xgecko 03-22-12 07:06 AM

put a bit of clear nail polish on the threads of the replacement bolts...

Scrodzilla 03-22-12 07:08 AM

Loctite > clear nail polish.

Get your own thread. ;)

Not always, it doesn't crack turn to dust under vibration like blue, plus its cheaper.

point taken though......

Scrod do you know if the Token Track Hub is just a rebranded Novatec one?

illdthedj 03-22-12 02:29 PM

scrod: do you ride any geared bikes? curious.

I'd be genuinely surprised if the answer were yes, to tell the truth. :lol:

I have a Bianchi Campione that very rarely gets ridden except for on the trainer in the winter.

Wait, wait, wait, Scrod not only has a road bike, but it has actual drops (instead of risers)?

Dude, you're a kook. I had drops on my 725 and have them on my Kagero:

Shhh . . . why would you reveal to everyone that I haven't actually checked your PedalRoom recently? :innocent:

Hey Scrod, I just put some new omniums and a new chain on. This is first day, and the noise is driving me crazy. I've measured chainline, front is about 41.7mm and rear is 42mm, The chain is 1/8" (Z410sl if that matters :P) Now I'm wondering if its the 3/32' cog in the back (It has about 1.5k miles on it) it doesn't look that worn. Or Do I need to break in the chain and chainring?

UCF Eric 03-22-12 11:38 PM

Scrod, while not using my speedplays and road shoes I tend to develop hot spots on my commuter setup. Do you have any pedal recommendations that could help get rid of hot spots? I know switching to something that has a stiff sole would help, but other then that. Thanks.

The Omnium chainring is pretty loud when it's new. Same with Z410 chains. Make sure your chain isn't too tight and keep it lubed.

Unless you have huge feet, MKS GR-9s should do the trick.
