CXD 3803 LLB W XD 15 Ceramic (Radial) 17x26x10

XD-15 ceramic bearings use a different material than any other bearing on the market and are exclusively for Enduro bearings. XD-15 is a very special nitrogen-infused steel material that will not rust or corrode. Even if you walk in salt water or in a caustic dietary drink that you can spill, it will not be affected. Even dirt or sand inside will not wear it out; this will simply make the running rings smoother. The production process of this steel involves re-melting a very high quality martensitic stainless steel from the end of an electrode. This happens in a highly controlled re-melting chamber while introducing nitrogen gas, producing a homogeneous steel, free of natural carbides and an ultimate resistance to fatigue. A super strong and strong steel, perfectly combined with silicon nitride ceramic balls of class 3, XD-15 bearings start great and get even better with driving over time. While other bearings are best on the day you buy them from the box and degrade from there, the XD-15 bearings improve over time, even years later. Not only do you save watts, you also save maintenance time. XD-15 is the pinnacle in bicycle bearing technology. Dimensions: 17x26x10
