All Enduro bottom brackets are manufactured to the highest standards at the Enduro Bearings production facility in California, USA. This complete bottom bracket features Angular Contact, 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. Though stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. Enduro Bearings also uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements. We are so confident in the quality and performance of theses bearings, Enduro provides a three year anti-corrosion guarantee.

This is just one of the huge range of solutions that Enduro makes for the wide range of bottom bracket standards on the market today. Enduro offers a solution for just about any configuration at multiple price/performance levels, ranging from standard ABEC-3, up to XD15 Ceramic Hybrid bearings featuring a lifetime guarantee.
