SO my buddy's 5.7 headset is all notched out (and yes, the bearings are in the right way). Near as I can tell, the lower bearing is to blame. The upper bearing is an ACB and seems to be fine. The lower bearing is what Pivot calls a "semi-sealed" cartridge bearing and yeah, semi-sealed = not really = fail. Are any of you swapping out the el-cheapo lower bearing and race for a Cane Creek lower assembly? If so, has it been a good fix or should I just get a whole new headset for him? The headset wasn't over-tightened either.
