ENDURO BKC-0846 XD15 TORQTITE CERAMIC ANGULAR BB BB30 & 30MM - BLK

BKC-0848 - TorqTite, Ceramic-Hybrid, XD-15, Angular Contact, Bearing Bottom Bracket for PF30 Framesets and 30mm Cranksets (current spindle length standard of 104mm or longer)

An Enduro Bearings exclusive, our XD-15 Pro BBs feature XD-15 15-degree Angular Contact cartridge bearings pressed into precision machined aluminum cups that thread directly into the BB shell. Utilizing XD-15 cryogenically treated nitrogen steel, Enduro XD-15 Pro bearings deliver a sealed 15-degree angular contact bearing in a standard cartridge. Deep-groove raceways accommodate maximum-sized Grade 3 Silicon Nitride ceramic balls for increased contact area, enhanced performance, and extended longevity. Manufactured to the highest standards at our California facility, these bearings combine corrosion-proof steel races with ceramic balls in a proprietary process engineered for ultimate high-performance results. Unlike conventional ceramic-hybrid bearings that degrade over time, XD-15 bearings actually improve with use—the balls smooth the races further as they wear in, delivering faster, smoother performance that only gets better.

Bike Radar called the XD-15 "Hands down, the best bottom bracket we have ever tested"—and we back that confidence with an unlimited lifetime bearing and race warranty. What sets these bearings apart is their unique ability to improve with use. As the ceramic balls wear in, they actually smooth the races further, delivering faster, smoother performance over time. Unlike other ceramic-hybrid bearings that peak on day one then gradually degrade, XD-15 bearings maintain their speed and efficiency advantages indefinitely, continuously getting better the more you ride.

With over 50 bottom bracket options across multiple price and performance levels, Enduro has a solution for virtually every frame and crankset combination. Choose from threaded designs for BSA, BSA 30, Italian, and T47 systems, or our innovative thread-together Torqtite press-fit brackets and Delrin Cup options. We even offer flanged, double-row bearings for 30mm cranksets in BB86 shells. Whatever your setup, find the perfect fit for your bike.
