ENDURO Bottom Bracket for T47 External to Sram DUB XD-15 Pro [BKC0771]

Enduro Bearings' exclusive ceramic bearings with XD15 nitrogen steel races have been the ultimate longevity and low-friction story in the cycling industry for over 12 years. This extra tough, stainless material will not corrode or rust as most other ceramic hybrids on the market will. While every other ceramic bearing rolls best the day you install it and then declines, XD15 bearings actually improve over time and become smoother. XD15 bottom bracket bearings have an angular contact design to ensure smooth rolling, full ball contact, and are designed to work with the Pre-Load systems that every crank uses now. They area pressed into precision-machined cups, guaranteeing accurate alignment when installed into your T47 threaded frame.
