The bottom bracket category is more complex than any other drivetrain component — not because the part itself is complicated, but because the number of standards in play is. Bottom brackets connect your crankset to your frame, and the combination of frame shell standard (threaded BSA, press-fit BB86, T47, PF30, BBRight) and crankset spindle diameter (Shimano 24mm, SRAM DUB, GXP, 30mm) determines exactly which BB you need. Getting that combination right is the first step; bearing quality is the second.

The RA Cycles bottom bracket collection covers both. CeramicSpeed and Chris King anchor the high end with ceramic and coated options that reduce friction and extend service intervals. Enduro Bearings and Wheels Manufacturing cover angular contact and standard steel options across dozens of shell and spindle combinations. Campagnolo factory-compatible BBs round out the lineup. With 400+ SKUs, this is one of the most comprehensive BB selections available.
