Went on a 25 mile ride with a good group of guys and a new kid that just moved from Cali. half way through the ride he realized he was binding the **** out of the omnoms he put on his 721. As soon as he would tighten the crank bolt it would bind up against the bottom bracket. Couldnt he just add a spacer between the bb and crankarm? I checked the bearings and they seemed pretty beat up already (felt gritty when I rotated it) but if he doesnt tighten the arm enough its just gonna come loose.

he was kinda giving up on them and wanted square taper again.
