The Enduro Bearings BSA 73mm - BB - XD15 Ceramic - 24mm is a top choice for cyclists seeking reliable performance. Designed for 73mm BSA framesets, this bottom bracket is compatible with Shimano 24mm cranksets and includes an adapter for SRAM GXP cranksets. The Enduro Bearings BSA 73mm - BB - XD15 Ceramic - 24mm features XD-15 ceramic-hybrid bearings, known for their durability and smooth operation.

These bearings are housed in precision-machined aluminium cups that thread directly into the bottom bracket shell. The XD-15 Pro bearings use deep-groove raceways and Grade 3 Silicon Nitride ceramic balls, enhancing contact area and boosting performance over time. Manufactured in California, USA, these bearings are built to last, combining corrosion-proof, cryogenically treated nitrogen steel races with ceramic balls for a high-performance setup.

One standout feature is that these bearings improve with use. As they wear in, the balls smooth the races, offering better performance compared to other ceramic-hybrid bearings that may degrade over time. Enduro Bearings is confident in their product, offering an unlimited lifetime warranty on the bearings and races.
