I’ve got a Trek with a BB92 bottom bracket. I’ve not had much life (around 1 year) from any bottom bracket on this or my other bike with a BSA BB until I switched the BSA one for a Chris King. I’ve had real trouble lately with the BB92 because I was running cranks with a 30mm axle but they died recently so I’m swapping back to a 24mm axle.
I’ve got a couple of options –
– A used Chris King Pressfit 24 BB
– A new Wheels Manufacturing PF92 BB
The King one I’d hope would last forever once it’s in, but the Wheels Mfg one has flanges which you fit a BB tool to and two halves screw together. I like the idea of that for replacement, but their instructions indicate that the bearings will still need replacing. That replacement looks basically the same as faffing about bashing a normal BB92 out the frame, but from the cups. At least with that option I can do it out of the frame on a workbench, which is much easier.
Anyone any experience with either? Will the King last for ever or am I better off going for the serviceable option?
