Enduro Bearings presents the exclusive XD-15 Ceramic-Hybrid bearings featuring corrosion-resistant, cryogenically treated nitrogen steel races paired with Grade 3 Silicon Nitride ceramic balls. This unique combination delivers top-tier performance and durability. The deep-groove raceways accommodate larger ceramic balls, increasing contact area for enhanced efficiency and extended service life. Filled with 90% Kluber NBU52 grease, these bearings improve smoothness over time and resist washout by adhering to the balls and continuously returning to the ball path for optimal lubrication.
A standout characteristic of these bearings is their ability to improve with use, unlike typical bearings. As they break in, the balls further smooth the raceways, enhancing performance. While competing ceramic-hybrid bearings may offer speed and power benefits initially, Enduro XD-15 bearings not only match those advantages from day one but continue to become faster and smoother over time. In contrast, other ceramic-hybrids tend to degrade in performance. These bearings are commonly used as direct replacements for Campagnolo Ultra Torque cranksets.
