ENDURO BEARINGS Torqtite bottom bracket - bbright to 30mm - xd-15 pro - black

Upgrade your mountain biking setup with the Enduro Bearings exclusive XD-15 Pro bottom bracket. Designed for current spindle lengths of 104mm or longer, this high-performance angular contact bearing features XD-15 15-degree sealed cartridges pressed into precision-machined aluminum cups that thread directly into the BB shell. Crafted from the same XD-15 steel as our renowned Corsa bearings, these bearings utilize deep-groove raceways and Grade 5 Silicon Nitride ceramic balls for maximum contact area, enhanced performance, and durability. Manufactured in California, USA, the XD-15 Pro combines corrosion-proof, cryogenically treated nitrogen steel races with advanced ceramic balls in a proprietary process, delivering unmatched high-performance reliability. Recognized by Bike Radar as hands down the best bottom bracket we have ever tested, these bearings improve with use, becoming smoother over time—unlike other ceramic-hybrid bearings that may slow down. Backed by a lifetime warranty against wear and corrosion, the XD-15 bearings offer sustained speed and efficiency. Enduro offers over 50 different bottom bracket options, including threaded BSA, BSA 30, Italian, T47, press-fit, and flanged double-row models, to fit a wide range of bicycle frames and cranksets.
