just rebuilt my (foddrill) combo spindles after a year and a half of wellsville riding. the kingpins appear to be in excellent shape, the surface where the torrington bearings ride is pretty much intact. the link pins had grooves from the bronze bushings which kinda suprised me because there made of 300m materal. i thought that the bushings would have taken more of a beating. i grease them after every ride (zerk fittings) i've been told that under race conditions, the guys out west pull then apart clean and regrease after each race. while i'ed like to think that i ride hard, it's nowhere near the wear and tear of racing. although they have grease fittings, i'm going to pull them apart and regrease them every 5-6 rides to see if i can extend the time between r/b's.
