BB86/92 XD15 Pro Bottom Bracket 30mm

The Enduro Bearings BB86/92 XD15 Pro Bottom Bracket 30mm is a top choice for cyclists seeking durability and performance. Designed specifically for BB86/92 framesets and BB30 style cranksets, this bottom bracket offers a seamless fit and exceptional functionality.

What sets the Enduro Bearings BB86/92 XD15 Pro Bottom Bracket 30mm apart is its use of XD-15 15° Angular Contact cartridge bearings. These bearings are pressed directly into the bottom bracket shell, ensuring a secure and efficient setup. The XD-15 Pro bearings are crafted from the same high-quality XD-15 steel as the XD-15 Corsa bearings, providing a 15º angular contact sealed bearing in a standard-sized cartridge.

These bearings feature deep-groove raceways, allowing for maximum-sized Grade 3 Silicon Nitride ceramic balls. This design increases the contact area, enhancing performance and longevity. Manufactured to the highest standards at Enduro Bearings' facility in California, USA, these bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride Grade 3 ceramic balls. This unique process results in a high-performance bearing setup.

One of the standout features of these bearings is their ability to improve with use. As they wear in, the balls smooth the races, making the bearings faster and smoother over time. Unlike other ceramic-hybrid bearings that may slow down, the Enduro XD-15 bearings continue to enhance their performance.
