ENDURO BEARINGS Torqtite bottom bracket - bb386 to 24mm - xd-15 pro - black

Experience superior performance with the Enduro Bearings exclusive XD-15 Pro Bottom Bracket. Crafted with XD-15 15-degree angular contact cartridge bearings pressed into precision-machined aluminum cups, these bottom brackets thread directly into your BB shell for seamless installation. Made from the same high-strength XD-15 steel as our Corsa bearings, they feature sealed, deep-groove raceways and Grade 5 Silicon Nitride ceramic balls for enhanced contact area, durability, and smoothness. Manufactured in California, USA, these bearings combine corrosion-proof, cryogenically treated nitrogen steel races with advanced 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. We back our XD-15 Ceramic-Hybrid bearings with a lifetime warranty against wear and corrosion. Unlike other bearings, they improve with use — the balls wear in and create an even smoother ride over time. While many ceramic-hybrid bearings claim initial speed and power benefits, Enduro XD-15 bearings become faster and smoother with continued use, outperforming competitors. Finding the perfect bottom bracket for your bike can be challenging, but Enduro offers over 50 types, including threaded options for BSA, BSA 30, Italian, and T47 systems, as well as press-fit solutions like Torqtite and Delrin Cup models. We even provide flanged, double-row bearings for 30mm cranksets in BB86 shells.
