ENDURO BKC-0861 XD15 TORQTITE CERAMIC ANGULAR BB BB86/92 & SHIMANO - BLACK

Enduro Bearings presents the exclusive XD-15 Pro bottom brackets, featuring XD-15 15-degree angular contact cartridge bearings housed in precisely machined aluminum cups that thread directly into the BB shell. Crafted from the same XD-15 steel as the XD-15 Corsa bearing, these sealed bearings deliver outstanding angular contact in a standard cartridge size. With deep-groove raceways, they accommodate large Grade 3 Silicon Nitride ceramic balls, enhancing contact surface, durability, and performance. Manufactured to exacting standards in California, Enduro XD-15 assemblies blend corrosion-resistant, cryogenically treated nitrogen steel races with premium Silicon Nitride ceramic balls for unmatched bearing quality and longevity.

Bike Radar hailed the Enduro XD-15 bottom bracket as "hands down, the best bottom bracket we have ever tested" due to its unique performance characteristics and durability. Unlike typical ceramic-hybrid bearings, the XD-15 bearings improve with use—the silicon nitride balls wear into the races, creating an even smoother surface over time. This results in enhanced speed and efficiency as the bearing breaks in, rather than performance degradation seen in other brands. Backed by an unlimited lifetime bearing and race warranty, the XD-15 ensures long-lasting, consistently exceptional performance that only grows better with continued riding.

Selecting the ideal bottom bracket for the diverse range of bicycles available can be challenging. Enduro provides over 50 distinct bottom bracket models tailored to different shell specifications and crankset combinations, spanning various price and performance categories.
