The ultimate upgrade
An Enduro Bearings exclusive, our XD-15 Ceramic-Hybrid bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls in a proprietary process that results in the ultimate high-performance bearing setup. The deep-groove design raceways allow maximum-sized Grade 3 Silicon Nitride ceramic balls for increased contact area and improved performance and longevity. Dual-lip labyrinth (LLB) seals to protect from the elements and contain the 90% fill Kluber NBU52 grease that runs smoother with time and is highly resistant to being washed out.

The most impressive feature of XD-15 ceramic-hybrid bearings is that they only get better with time and use, unlike other bearings. As the bearings wear in, the super-hard ceramic balls make the XD-15 races even smoother. So, compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD-15 bearings not only provide the same initial benefits on day one but will become faster and smoother with time and use. In contrast, the other ceramic-hybrid options will only get slower. We are so confident in the performance of XD-15 Ceramic-Hybrid bearings that we offer an unlimited lifetime bearing and race warranty.

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

The Enduro line of bearings is available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls. Our bearings are always engineered with the deepest groove races possible to accommodate the most oversized balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
