Enduro Bearings presents the XD-15 Pro BBs, exclusive angular contact cartridge bearings installed in precisely machined aluminum T47 cups that thread directly into the bottom bracket shell. Built with the same XD-15 steel as the XD-15 Corsa, these 15° angular contact sealed bearings fit standard cartridge sizes. Their deep-groove raceways accommodate large Grade 3 Silicon Nitride ceramic balls, enhancing contact surface for superior performance and durability. Crafted at Enduro’s California facility, these bottom brackets feature corrosion-resistant, cryogenically treated nitrogen steel races paired with premium ceramic balls, delivering a top-tier bearing solution.
Bike Radar named the XD-15 "undoubtedly the best bottom bracket we've ever tested," and we stand behind that claim with an unlimited lifetime warranty on bearings and races. What sets these bearings apart is their unique ability to improve with use; as they break in, the balls polish the races, creating an even smoother surface. Unlike other ceramic-hybrid bearings that may lose performance over time, Enduro XD-15 bearings deliver immediate speed and power benefits while continually becoming faster and smoother with continued use.
Selecting the ideal bottom bracket for today’s diverse bicycle designs can be challenging. Enduro provides over 50 bottom bracket models tailored to a wide array of shell and crankset combinations, spanning various performance and price levels. Our threaded options cover BSA, BSA 30, Italian, and the durable T47 standards. For press-fit systems, we developed the widely imitated, thread-together Torqtite bottom brackets alongside press-fit Delrin Cup variants. Additionally, we offer flanged, double-row bearings designed specifically for 30mm cranksets in BB86 shells.
