We are so confident in the performance of XD15 Ceramic-Hybrid bearings, that we offer a full lifetime warranty against wear and corrosion. – 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. Finding the right bottom bracket solution for the ever-growing range of bicycles on the market is not always an easy task. At Enduro we currently offer over 50 different types of bottom brackets for various bottom bracket shell and crankset combinations in multiple price/performance levels. Enduro bearings offers threaded options for BSA, BSA 30, Italian and the robust T47 system. For press-fit bottom brackets we created the oft-copied, thread-together Torqtite bottom brackets as well as press-fit Delrin Cup options. We even offer flanged, double-row bearings to fit 30mm cranksets in BB86 shells!
