Enduro Bearings 152610 CXD DR LLB XD-15 Ceramic Bearing, 15x26x10

XD-15 ceramic bearings use a different material than all other bearings on the market and are exclusively designed for enduro applications. XD-15 is a very special nitrogen-infused steel material that does not rust or corrode. Even when in contact with saltwater or an acidic drink that you might spill, it will not break down or be affected. Dirt or sand inside does not wear them out but instead polishes the raceways smoother. The production of this steel involves remelting high-quality stainless steel at the end of an electrode. This process takes place in a highly controlled remelting chamber with nitrogen gas input, resulting in a homogeneous steel with the highest fatigue strength. A super strong, solid steel, perfectly paired with Grade 3 ceramic balls, XD-15 bearings improve over time. While other bearings are better on the day of purchase and then fail, XD-15 bearings get better as time goes on. This not only saves you watts but also maintenance costs. The XD-15 is the pinnacle of bicycle bearing technology. Dimensions: 15x26x10 medium/low contact seal.
