So I've noticed a consistent problem I get with my cranksets, and I was wondering if this is just a "bad mechanic" issue or if other Clydes are encountering similar issues with a square taper crank.
Cranks: FSA Vero, and Sugino XD700
Bottom Bracket: Shimano UN54
Issue: Click/creak when placing full weight on cranks at horizontal position, then shifting cranks 180 degrees to opposite horizontal, as though there is play at the taper interface. Problem is not loose crank bolts; bolts are at or above torque spec.
I talked to some of the LBS shop geeks who work on clyde rides, and after checking my crankbolts with a torque wrench one of the wrenches suggested that I may have consistently over-torqued my crankbolts and bottomed out the taper so it cannot lock fully any longer. This is a distinct possibility, as I don't own a torque wrench and just sort of Sasquatched the bolts on there when replacing the original cranks, and have re-tightened things since the install. The other possibility is that my size and persistant stand-and-hammer hill assaults just warp the taper interface on the crank, and I've run out of taper to tighten it down on.
Do other big riders using square taper cranks find they're getting loosening issues at the taper interface? Am I just being a bad mechanic and overtightening that bolt, or am I being an overly abusive rider and wrecking that taper interface? Maybe a little bit of both?
