The BBRIGHT TorqTite XD15 Pro 30mm Bottom Bracket from Enduro Bearings is a top-quality option for BBright frames and 30mm cranksets. This exclusive product features XD-15 15° Angular Contact cartridge bearings, which are built into precision machined aluminium cups that can be easily threaded into the BB shell. With deep-groove raceways and Grade 3 Silicon Nitride ceramic balls, the XD-15 Pro bearings offer maximum contact area, improved performance, and longer life. These bottom brackets are manufactured to the highest standards in California, USA, using a proprietary process that combines corrosion-proof, cryogenically treated nitrogen steel races with ceramic balls. The result is the ultimate high-performance bearing setup.One of the most impressive features of these bearings is that they actually get better with use. As the bearings wear in, the balls make the races even smoother, ensuring that they continue to perform at their best over time. This sets them apart from other ceramic-hybrid bearings on the market, which may claim initial advantages but don't improve with use like the Enduro XD-15 bearings. In fact, other options may even deteriorate over time, while the XD-15 bearings continue to get faster and smoother.Enduro Bearings offers a wide range of bottom bracket solutions for different types of bicycles, with over 50 different options available.
