chain noise dilemma
 

I have been experiencing awful binding/clicks on my '73 Nishiki fixie conversion on the downstrokes of each crank. with the chain off, i spun the cranks and eyed up the chainring, and it doesn't spin perfectly on axis, it wobbles a bit.

thinking (and hoping) I might have a bent spindle (stock from the 70's), I tried repacking my bottom bracket with another spindle to find that the chainring still wobbled a bit. i took the chainring off of the spider, and it layed flat on a counter, and I couldn't see any bending in it, so its not that either.

I can't bring myself to accept that perhaps my cranks/spider is(are) bent (they are jawesome stock Sugino Mighty Competitions). I just don't want to fork up the money for a new crankset. they are so f'ing expensive.

SO...

1. could it be possible that my bearings/races in my bottom bracket are causing the spindle to rotate off axis?

2. Any recommendations on track cranksets?

Well just to say, just because you cant see anything bent doesn't mean it isn't. This happened to me on my sugino RDs. one of the spiders seem to have bent but I still ride on it with no problem.

Chain too tight?

+1 on the chain- unless your chainline is whack

Chain might be binding at the tight spots. Try slackening the chain a bit more.

my chainline is real good, and i have plenty of slack in the chain. i know the chain's not binding from too much tension... it just sounds like that scenario.
