Well my BB bearings finally gave up the ghost so I decided to change the BB myself. Got everything out with no problem but now having trouble picking the right replacement set.

The crankset is the original M552

On the bearing it says SM-BB71-41

I am not sure which bearing to order or what is compatible.

Thanks for any help.

EDIT - after 2 hours of research I got it. Confusing to say the least
