ENDURO BEARINGS Torqtite bottom bracket - bb30 to 24mm - xd-15 pro - black

Experience superior performance with the Enduro Bearings exclusive XD-15 Pro bottom bracket, designed for BB30 framesets and Shimano 24mm cranksets. Featuring XD-15 15-degree angular contact cartridge bearings pressed into precision-machined aluminum cups, these bearings thread directly into the bottom bracket shell for easy installation. Crafted from the same high-grade XD-15 steel as our renowned Corsa bearings, the XD-15 Pro offers sealed, deep-groove raceways with large Grade 5 Silicon Nitride ceramic balls, providing increased contact area, enhanced durability, and improved performance. Manufactured in California, USA, these bearings combine corrosion-resistant, cryogenically treated nitrogen steel races with premium ceramic balls through a proprietary process, delivering unmatched high-performance reliability. Recognized by Bike Radar as “hands down the best bottom bracket we have ever tested,” the XD-15 Pro is backed by a lifetime warranty against wear and corrosion. Unlike other bearings, these actually improve with use—balls settle into the races, making them smoother over time. They maintain initial speed and power advantages while becoming faster and smoother with continued riding, unlike other ceramic-hybrid options that tend to slow down. Enduro offers over 50 types of bottom brackets, including threaded options for BSA, BSA30, Italian, and T47 systems, as well as press-fit solutions like the Torqtite and Delrin Cup models, plus flanged, double-row bearings for 30mm cranksets in BB86 shells.
