Ditto. I ran UN52 (then UN55) and UN72 units and never had a bad experience with em aside from the bearings wearing out, and even then that took yeeeears. Still have one on my winter beater track bike. Cranks though..... Woof! Last pair of squares I ran on a MTB were Turbines, and after the taper went to hell they were happy to upgrade me to ISIS. And that was when the bearing troubles began.
