i built up my beautiful new fixed gear bike with new iro wheels and new shimano cranks / bottom bracket. i bought all the parts with a 42mm chainline in mind so as to avoid any nasty problems with spacers and what-have-you. but... I'm getting some noise from the rear sprocket as the chain passes. From reading previous posts i would assume this is a chainline problem but i'm fairly confident that its pretty dead on straight. is there anything else that can cause this?
Maybe it's gotta break in a bit. I put a new chain on a few weeks ago and it was noisier than my rusty 10-speed beater with loose spokes and banged up wheel. But after a week or so it got less and less noisy and now I can't even hear it.
yeah, noise occurs when just spinning the wheel by hand. back pressure noise i would expect; my other fixie is silent crusing. i built that one up with a used chain though so maybe i just have to break this one in. chainline "issues" have me so paranoid...unless anyone thinks different i guess i'll just wait it out.
to be more clear, the noise persists at tensions that are way too lose and tensions that way too tight (as to restrict drive train movement). ruling out all these annoyingly technical factors seems to be too easy to be true but is it possible just to noisely break in a new chain in [especially in an intense drive train situation (ie. 14 x 42 fixed gear) ]?
ive found that SRAM chain are pretty quiet... how do you go about gauging your chainline? if you think it is spot on, then its probably pretty good. 1mm off chainline wont kill you, some drivetrains are just noisier.
