BKC-0801 - BSA Thread-In, Ceramic-Hybrid, XD-15, Angular Contact, Bearing Bottom Bracket for 68mm BSA framesets and Shimano (24mm) Cranksets.
The XD-15 Pro BBs are an exclusive offering from Enduro Bearings. Crafted with precision and innovation, these bottom brackets feature XD-15 15° Angular Contact cartridge bearings snugly encased in meticulously machined aluminium cups, seamlessly threading directly into the BB shell. Sharing the same XD-15 steel composition as the acclaimed XD-15 Corsa bearings, Enduro XD-15 Pro bearings boast a 15º angular contact sealed bearing within a standard-sized cartridge. With deep-groove raceways facilitating the accommodation of maximum-sized Grade 3 Silicon Nitride ceramic balls, these bearings ensure heightened contact area, leading to superior performance and longevity.
Manufactured to exacting standards at their production facility in California, USA, Enduro XD-15 bottom brackets epitomise quality and precision. Combining corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls in a proprietary process, these bearings represent the pinnacle of high-performance bearing technology. The thread-in solution facilitates the seamless integration of Shimano-type 24mm cranks into BSA threaded bottom bracket shells, eliminating any installation hassles. Enduro Bearings are so confident in the durability and reliability of their product that they offer an unlimited lifetime bearing and race warranty.
What truly sets these bearings apart is their remarkable ability to improve over time. Unlike conventional bearings, which may degrade with use, XD-15 bearings actually become smoother as they wear in. While other ceramic-hybrid bearings may boast initial speed and power advantages, Enduro XD-15 bearings not only match these advantages from day one but also continue to improve in speed and smoothness with prolonged use. In contrast, other ceramic-hybrid options tend to decline in performance over time.
