Utilizing Enduro Bearings' XD-15 Ceramic-Hybrid technology, our bearings undergo a unique process of combining nitrogen steel races with Grade 3 Silicon Nitride ceramic balls. This exclusive design results in the ultimate high performance setup, with deep-groove raceways allowing for maximum sized ceramic balls. The LLB seals protect from external factors, while the Kluber NBU52 grease not only runs smoothly over time, but also offers strong resistance against washout.

The most remarkable quality of XD-15 ceramic-hybrid bearings is their continuous improvement over time and use, unlike other bearings. As the bearings break-in, the highly durable ceramic balls contribute to a smoother performance of the XD-15 races. While other ceramic-hybrid bearings may claim immediate speed and power enhancements, the Enduro XD-15 bearings not only provide the same benefits at the start, but also continue to increase in speed and smoothness with use, in contrast to other options which may experience a decrease in performance. We stand behind the exceptional performance of XD-15 Ceramic-Hybrid bearings by offering an unlimited lifetime warranty for both bearings and races.

This bearing is used primarily in lightweight quick-release hubs and some pedals.

The ENDURO bearings come in various materials such as high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. With deep groove races and dual-lip seals, our bearings provide the utmost protection against external factors and accommodate large balls for maximum performance.
