I’ve been trying to eliminate crank/bb noise in several different Sugino RD2 cranksets over the years with no luck. Always a faint click, once per revolution on the crankarms.
I’ve tightened EVERYTHING. I’ve tried grease and locktite in different ways on crank bolts and chainring bolts. The mechanics all say everything looks good. I’ve had BB shells faced. I’ve installed the BBs myself, and had shops do it. Always tons of grease. I’ve done this with several frames, and many different pedals.
I’ve heard some say you have to tighten the crank bolts, ride, tighten, ride, tighten, ride, tighten, etc... And I have done that too.
Still a click. I’ve had several of these sets. New. All the same problem.
My understanding is that it’s more difficult to get the system quiet because of reversal of torque from riding and skidding involved in street riding fixed, vs on the track where there’s not much reason to skid in the velodrome.
But I haven’t tried non-Sugino cranksets or bottom brackets.
Is this a common problem to do with all square taper fixed gear street riders, or just Sugino systems?
I have a hard time believing Sugino would continually make a noisy product.
I’ve had several different non-square-taper systems, and they are always quiet. It makes me think square tapers are just bad for street riding fixed.
