The Enduro Bearings BB386 Torqtite XD-15 Pro Bottom Bracket 30mm is a top choice for cyclists seeking durability and performance. Designed specifically for BB386 framesets and wide 30mm cranksets, this bottom bracket features the exclusive XD-15 15° Angular Contact cartridge bearings. These bearings are housed in precision-machined aluminium cups that thread directly into the BB shell, ensuring a secure fit.

Enduro Bearings uses the same XD-15 steel found in their XD-15 Corsa bearings, offering a 15º angular contact sealed bearing in a standard-sized cartridge. The deep-groove raceways accommodate large Grade 3 Silicon Nitride ceramic balls, enhancing contact area and boosting both performance and longevity. Manufactured in California, USA, the Enduro Bearings BB386 Torqtite XD-15 Pro Bottom Bracket 30mm combines corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride ceramic balls, resulting in a high-performance bearing setup.

One standout feature of these bearings is their ability to improve with use. As they wear in, the balls smooth the races, making them faster and smoother over time. This is unlike other ceramic-hybrid bearings that may slow down with use. Enduro Bearings is confident in their product, offering an unlimited lifetime warranty on both bearings and races.
