BKC-0881 - TorqTite, Ceramic-Hybrid, XD-15, Angular Contact, Bearing Bottom Bracket for BB30 Framesets and Shimano 24mm Cranksets (includes adapter for SRAM GXP cranksets) This exclusive Enduro Bearings XD-15 Pro bottom bracket is designed for BB30 framesets and Shimano 24mm cranksets. The XD-15 Pro features XD-15 15° Angular Contact cartridge bearings that are pressed into precision machined aluminum cups. These cups thread directly into the BB shell, making installation simple. With deep-groove raceways and Grade 3 Silicon Nitride ceramic balls, the XD-15 Pro bearings offer increased contact area and improved performance. Manufactured to the highest standards in our California, USA production facility, these bottom brackets are built to last. Our XD-15 bearings combine nitrogen steel races with ceramic balls in a proprietary process, resulting in the ultimate high performance bearing setup. We are so confident in the quality of our bearings that we offer an unlimited lifetime bearing and race warranty. Unlike other bearings, our XD-15 bearings actually get smoother with use. As the balls wear-in, the races become even smoother, resulting in faster and more efficient performance. Other ceramic-hybrid options on the market may claim speed and power advantages, but they will only get slower with time. Enduro XD-15 bearings, on the other hand, continue to improve. With over 50 different types of bottom brackets available, we have a solution for every bicycle and crankset combination. Our threaded options include BSA, BSA 30, Italian, and the T47 system. For press-fit bottom brackets, we offer the thread-together Torqtite system and press-fit Delrin Cup options. Whether you have a BB86 shell with a 30mm crankset or any other bottom bracket configuration, we have the perfect solution.
