The C-BEAR BB386EVO Shimano Race bottom bracket fits Shimano Hollowtech II cranks and other 24 mm axle cranks (not GXP). It has ceramic bearings that have been optimized for low-friction, efficient running. So use this BB386EVO bottom bracket best on the Road and not off-road.

Specific Applications C-BEAR (Ceramic BEARings) Bottom brackets are available with 2 different ceramic bearing types. The Race bottom bracket bearings are designed for low rolling resistance and are intended for use on dry roads. In a study carried out by the independent Friction Facts Laboratory, they were ranked top 3 in terms of bottom bracket efficiency (the first place went to an unsealed bottom bracket for indoor use).
High-Quality Bearing Cups The bearing cups of the C-BEAR bearings are not made of plastic but of CNC precision-machined aluminium. C-BEAR committed itself to an anti-plastic posture very early on, in 2011/2012, when plastic additives were just coming into fashion. Metal housings mean higher accuracy, lower tolerances, and the avoidance of flex and deformation.
