Enduro Bearings' XD-15 Ceramic-Hybrid bearings are a unique offering featuring corrosion-proof, cryogenically treated nitrogen steel races and Grade 3 Silicon Nitride ceramic balls. Utilizing a proprietary process, this bearing setup delivers unparalleled high performance. The deep-groove design of the raceways allows for maximum-sized ceramic balls, resulting in increased contact area and improved performance and longevity. Additionally, the bearings come with dual-lip labyrinth (LLB) seals to protect against external elements. The included 90% fill Kluber NBU52 grease becomes even smoother over time and is incredibly resistant to being washed out.

The most notable aspect of the XD-15 ceramic-hybrid bearings is their continual improvement over time and use, surpassing other bearings. As the bearings wear-in, the incredibly durable ceramic balls greatly enhance the smoothness of the XD-15 races. Therefore, compared to other ceramic-hybrid bearings claiming speed and power benefits from day one, Enduro XD-15 bearings not only deliver the same initial advantages, but also become faster and smoother with use, while competitors' options only experience decreasing speeds. Our utmost confidence in the performance of XD-15 Ceramic-Hybrid bearings is backed by an unlimited lifetime bearing and race warranty.

This bearing is used primarily in lightweight hubs and pedals.

Our ENDURO bearings come in various materials such as high-carbon chromium steel, 440C stainless steel, and ceramic-hybrid options, including XD-15 with ceramic or stainless balls. Each bearing is expertly engineered with deep groove races to accommodate larger balls and features dual-lip seals for superior protection against the elements.
