I just had a brand new shimano hollowtech compact crank and BB put on my bike after some bad experiences with a truvativ elita one-piece crankset, namely: non-drive side side crank arm falling off and then eventually some super-loud BB ticking.
I was pleased as punch with the compact crank, it made the bike feel like new--lots of power, stiff, easy rotation, no noise, flawless shifting--until my last ride and this morning. sure enough, non-drive side crank arm under load is generating some little trt-t-t-t-t like noises, on the down and upstroke. No noise when pedaling easy.
The noise itself doesn't bother me so much, it's what it might say about the BB. Am I wrecking the BB threads or shell? Should I stop using it immediately? I'm pretty sure the shell has never been faced--could this be a source of the problem?
I'm somewhat unfamiliar with the hollowtech one-piece system. With square taper BB ticking I just reef on the BB to make sure it's snug in the shell and then reef on the crank bolts to make sure they're well on. Hollowtech seems like that might be a bad idea/overkill, as it seems to work more like a threadless headset.
Any suggestions, or is this a case of advanced diagnosis and treatment?
