• True, although the pf solution for bb's was really badly thought out. You might have much higher torque loading or rpms on an automotive press fit bearing, but the twisting loads acting on the BB area of the bicycle, with the (quite high) risk of deformation post welding due to insufficient wall thicknesses meant that it was always a bit hit and miss. Rob @hoops has a pf30 and has no problems, others have had much less luck. Fortunately no one has mentioned bb30!
