Enduro Bearings BKC-0796 – AC Bearing – BB for T47 and 24mm Cranksets

BKC-0796 – T47-Internal, Threaded, Ceramic Hybrid, XD15, Angular Contact Bearing, Bottom Bracket for T47 Framesets and Shimano 24mm Cranksets – 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 are pressed into precision-machined cups, guaranteeing accurate alignment when installed into your T47 threaded frame. We are so confident that we offer these bottom brackets with a lifetime warranty, which even covers wear and corrosion (the most common source of eventual failure). – Depending on the BB cup spline design and what you have in your shop, you may need one of our Pro Tools for installation. – Since these bearings are 15º Angular Contact design, they require a light preload to guarantee the best adjustment – Some cranksets have pre-load systems already built in, but if yours doesn′t, or if it is made of plastic, we would recommend our machined aluminum pre-load adjuster shown below for DUB and 30 mm cranksets. –
