ENDURO BKC-0805 XD15 CERAMIC ANGULAR BSA THREADED BB68 30MM-BLACK

Enduro Bearings’ exclusive XD-15 Pro bottom brackets incorporate XD-15 15-degree Angular Contact cartridge bearings housed in precisely machined aluminum cups that thread directly into the BB shell. Using the same XD-15 steel as the Corsa line, these bearings feature a 15-degree angular contact design within a standard cartridge size. Their deep-groove raceways accommodate larger Grade 3 Silicon Nitride ceramic balls, enhancing contact area for superior performance and durability. Manufactured to exacting standards in California, Enduro XD-15 bearings combine corrosion-resistant, cryogenically treated nitrogen steel races with premium ceramic balls for an exceptional, high-performance bearing solution.

This threaded bottom bracket lets you easily install 30mm/386 cranks into a BSA threaded shell. Praised by Bike Radar as "Hands down, the best bottom bracket we have ever tested," the XD-15 comes with an unlimited lifetime warranty on bearings and races. Unlike typical ceramic-hybrid bearings, these XD-15 bearings improve with use; as they wear in, the balls polish the races, enhancing smoothness and speed. While other ceramic-hybrid models may slow down over time, the Enduro XD-15 bearings deliver consistent performance gains, making them a superior choice for long-term reliability.
