Enduro Bearings T47 Asymmetrical XD15 Black 24mm Bottom Bracket Lifetime Warranty

The Enduro Bearings T47 Asymmetrical XD15 Black 24mm Bottom Bracket is engineered for cyclists seeking superior durability and performance. This premium component combines precision machining with innovative bearing technology, featuring the exclusive XD15 Pro 15-degree Angular Contact cartridge bearings. Designed to fit Shimano-type 24mm spindles, it threads directly into the T47 shell with ease, ensuring a secure and reliable connection that optimizes power transfer and reduces friction.

Manufactured in California, USA, the Enduro XD15 bearings utilize high-quality cryogenically treated nitrogen steel races and Grade 3 Silicon Nitride ceramic balls. This unique combination enhances corrosion resistance and longevity, delivering smooth operation that actually improves over time. Unlike conventional ceramic-hybrid bearings that degrade, the XD15 bearings refine their performance with use, providing cyclists with sustained speed and efficiency throughout their rides.

The T47 Asymmetrical standard offers a robust, thread-in solution that balances compatibility and strength, favored by brands such as Cervelo and Factor. Enduro Bearings’ extensive lineup addresses the diverse needs of modern bicycles, with over 50 models catering to different shell and crankset configurations. This model is no exception, equipped with the trusted XD15 Pro bearings, LLB seals, and premium Kluber CRC Marine Grease for optimal protection against the elements and wear.
