The Enduro BKC-08015 Bottom Bracket is a masterclass in engineering for riders who demand nothing short of excellence. Designed for 68mm BSA threaded frames and SRAM DUB 29mm cranksets, this bottom bracket features XD-15 ceramic-hybrid angular contact bearings – among the finest available anywhere.
Exclusive to Enduro, the XD-15 Pro bearing system uses deep-groove raceways and Grade 3 Silicon Nitride ceramic balls to deliver a larger contact area, exceptional durability, and incredible rolling efficiency. Unlike traditional ceramic hybrids, these bearings actually improve with use — delivering ever-smoother performance the more you ride.
Manufactured in California, USA, each bearing is built using cryogenically treated, corrosion-proof XD-15 nitrogen steel races, ensuring a lifespan that truly justifies the unlimited lifetime warranty. The precision-machined aluminium cups thread directly into the BSA shell for a straightforward, creak-free fit.
