CXD 6805 LLB - ABEC-5, XD15, Ceramic-Hybrid Radial Bearing - 25mm x 37mm x 7mm An Enduro Bearings exclusive, our XD15 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 for maximum sized Grade 3 Silicon Nitride ceramic balls for for increased contact area and improved performance and longevity. 90% fill Kluber NBU52 grease only runs better and smoother with time and is highly resistant to being washed out. It is engineered to stick to the balls and continually be pulled back into the ball path where it is needed. Find out why Bike Radar reported the XD15 Hands down, the best bottom bracket we have ever tested. We are so sure that you will agree, that we offer an unlimited lifetime bearing and race warranty. The most impressive feature of these bearings is, unlike other bearings, they only get better with use. As the bearings wear-in, the balls actually make the races even smoother. So when compared to other ceramic-hybrid bearings on the market that claim speed and power advantages on day one, Enduro XD15 bearings not only provide the same initial advantages on day one, but will get even faster and smoother with time and use, while the other ceramic-hybrid options will only get slower. The most common use for this bearing is as a direct replacement bearing for Shimano external cup BBs when using the plastic Shimano bearing insert. If you wish to avoid using the plastic insert, MR 2437 is the correct bearing for the application.
