ENDURO BSA ROAD XD-15 CORSA BB KIT BLACK

Enduro's top of the line BB solution, we press XD-15 45 Degree Angular Contact bearings into precision machined aluminum threaded aluminum cups that simply thread directly into the BB shell. Enduro XD-15 bottom brackets and bearings are manufactured to the highest standards at the Enduro Bearings production facility in California, USA. Our XD-15 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. This thread-in solution allows you to fit your Shimano 24mm cranks into your BSA threaded bottom bracket shell without any hassle. 

Please note that 45° angular contact bearings require much higher preload (12-26 inch Lb) than standard radial bearings. We highly recommend getting XD15 Corsa installed by a qualified professional mechanic. 

Find out why Bike Radar reported the XD-15 “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 XD-15 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.
