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

Discover the Enduro Bearings exclusive XD-15 Pro Bottom Bracket, featuring high-performance Ceramic-Hybrid angular contact cartridge bearings pressed into precision-machined aluminum cups that thread directly into your bike's BB shell. Designed for BBRight framesets and Shimano 24mm cranksets, these bearings utilize the same durable XD-15 steel as our renowned Corsa bearings, offering a 15-degree sealed angular contact design for superior performance.

With deep-groove raceways and large Grade 5 Silicon Nitride ceramic balls, XD-15 Pro bearings maximize contact area, enhancing durability, smoothness, and load capacity. Manufactured in California, USA, at the Enduro Bearings facility, these bottom brackets combine corrosion-proof, cryogenically treated nitrogen steel races with high-grade ceramic balls through a proprietary process, delivering unmatched high-performance reliability.

Bike Radar praised the XD-15 as hands down the best bottom bracket we have ever tested. Our confidence is so high that we offer a lifetime warranty against wear and corrosion. Unlike traditional bearings, XD-15 ceramics improve with use—balls and races become smoother over time, maintaining speed and power advantages while other hybrid bearings slow down. Perfect for the diverse and growing range of bicycles, Enduro offers over 50 types of bottom brackets, including threaded options for BSA, BSA 30, Italian, T47, and press-fit solutions like Torqtite and Delrin Cup models, even flanged double-row bearings for 30mm cranksets in BB86 shells.
