    creak - top dead center, non drive

    OK SS brainiacs, what's your diagnosis?

    I'm on a Yelli Screamy using a DMR STS tensioner.

    I get a little creak when my non-drive side crank passes through top dead center. It doesn't do this in the stand, but does do it while soft-pedaling through that part of the pedal stroke.

    My go-to moves for creak abatement are:
    1) remove BB, clean & grease, replace & torque
    2) remove crank arms, clean & grease, replace & torque
    3) remove chainring bolts, clean & grease, replace & torque

    I haven't done any of this yet. I'm curious what might be causing this creaking sound. If you were to do just one thing to eliminate such a creak, what would you do and why?

    as always tough to diagnose over the internet. I like your plan. going through the process will at lease eliminate the items you address. have you tried lifting up on pedals as you ride? pedaling without being clipped in on that side? keep experimenting to single it out as much as possible before tearing the thing apart.

    I've had a pedal that was properly torqued making a noise. i mentioned it to a mechanic, he grabbed a wrench and cranked it down tighter, noise gone.

    maybe check your cleats? lube pedals?

    Stop asking how much it weighs and just go ride it.

    I have a problematic BB (external cup bb30) so thats where I would look first. But once you're doing that it doesn't really make a lot of sense to skip the others.

    If I could do just one thing to fix it, it would be to replace with a white industries crank and a square taper BB. Someday...
    Yeah I only carry cans cause I'm a weight weenie.

    I had no noises until I replaced the chain ring.
    Now a single creak per rev even at low load.
    Only things touched were the chain, chain ring, ring bolts and re-tensíoning the DMR STS.

    Well, I found that my Time pedals were a little loose, so I tightened up the end caps, and then popped them off and greased up the threads and replaced them. No creaking on a 30 second ride on the street, will see what happens when I ride this evening.

    Pedals tend to "pop" when lube or looseness is a problem. It's most likely your seat.
