ENDURO BEARINGS T47 Internal Bottom Bracket to 24mm - XD-15 Pro - Black

BKC-0796 - T47 Internal Threaded Ceramic Hybrid Bottom Bracket for Shimano 24mm Cranks

Upgrade your mountain bike with the exclusive Enduro Bearings XD-15 Pro Bottom Bracket. Designed for T47 framesets and Shimano 24mm cranksets, this high-performance bottom bracket features 15 Angular Contact sealed cartridge bearings pressed into precision-machined aluminum cups that thread directly into your bike’s bottom bracket shell. Made from the same durable XD-15 steel as our renowned Corsa bearings, these bearings incorporate deep-groove raceways and Grade 5 Silicon Nitride ceramic balls for enhanced contact area, performance, and longevity. Manufactured in California, USA, they combine corrosion-proof, cryogenically treated nitrogen steel races with advanced ceramic balls in a proprietary process, delivering unmatched durability. Recognized by Bike Radar as the best bottom bracket we've tested, the XD-15 Pro offers a unique advantage: it improves with use, as the balls and races wear in to create an even smoother ride. Backed by a lifetime warranty against wear and corrosion, these bearings provide sustained speed and power advantages over time. Enduro offers over 50 types of bottom brackets, including threaded options for BSA, BSA 30, Italian, and T47 systems, as well as press-fit solutions like Torqtite and Delrin Cup models, and flanged double-row bearings for 30mm cranksets in BB86 shells.
