I finally dragged my 1x1 out of the shed where it's been living for far too long and took it out for a few rides.
I gave it a once-over before riding and found that both crankbolts were loose. I tightened them up, went out for my ride, and had them loosen up again during the ride.
I'm running lx (splined) cranks, with a relatively new bb. I pulled the bolts out, and found that the threads looked ok. The crankbolts were REALLY greasy, so I wiped the excessive grease off and reinstalled. One short ride later, the crank bolts are still tight. However, that short ride didn't involve much climbing, so I'm still concerned that they may loosen again.
My question is, what would make crankboolts loosen up? the crank arms, crank bolts, and bb are all in good shape. The spindle, crankarms, and chainring all appear true - I don't see any eccentric movement when I spin them. There was exessive grease on the bolts, but I don't really suspect that of causing problems... so why are they loosining up?
Any ideas?
