The Enduro Bearings T47 Asymmetrical XD15 Black 30mm bottom bracket is a top-tier component designed for cyclists who demand precision, durability, and high performance from their drivetrain. Featuring the exclusive XD15 Pro ceramic-hybrid bearings, this bottom bracket combines advanced engineering with cutting-edge materials to deliver exceptional smoothness and longevity. The T47 Asymmetrical design threads directly into the bike’s bottom bracket shell, offering a secure fit tailored to specific frame standards such as those used by Cervelo and Factor.
Crafted in California with meticulous attention to detail, the XD15 Pro bearings use a 15-degree angular contact cartridge system that enhances load handling and efficiency. The deep-groove raceways accommodate Grade 3 Silicon Nitride ceramic balls, maximizing contact area for reduced friction and superior performance. Thanks to a unique cryogenic treatment and corrosion-resistant nitrogen steel races, these bearings are built to withstand the harshest conditions while maintaining peak functionality. Remarkably, the bearings improve with use, becoming smoother and faster over time—a feature that sets them apart from other ceramic-hybrid options on the market.
Whether upgrading your existing bottom bracket or building a new bike, the Enduro Bearings T47 Asymmetrical XD15 is a reliable solution that balances innovation with proven technology. It comes pre-greased with Kluber CRC Marine Grease for optimal protection and is backed by a lifetime warranty against wear and corrosion. Enduro’s extensive range of bottom brackets, including threaded and press-fit options, ensures compatibility across a wide variety of crankset and frame combinations, making this product a versatile choice for serious cyclists.
