BSA 73mm - BB - XD15 Ceramic - 24mm xd-15

Brand:Enduro Bearings

Code:EB9596

BSA thread-in, ceramic-hybrid, XD-15, angular contact, bearing bottom bracket for 68mm BSA framesets.

Enduro Bearings' XD-15 Pro bottom brackets feature XD-15 15° angular contact cartridge bearings pressed into precision-machined aluminium cups that thread directly into the BB shell. These bearings utilise XD-15 steel and feature deep-groove raceways, allowing for maximum-sized grade 3 silicon nitride ceramic balls for increased contact area, performance, and longevity.

Manufactured in California, USA, using aircraft-grade metals, these bottom brackets combine corrosion-proof, cryogenically treated nitrogen steel races with silicon nitride grade 3 ceramic balls. The angular contact design allows for fine-tuning of preload. Unlike other ceramic-hybrid bearings, these bearings improve with use; as they wear-in, the balls make the races smoother. This thread-in solution allows for the fitting of Shimano-type 24mm cranks into BSA threaded bottom bracket shells. The design will not rust and is engineered to last significantly longer than standard ceramic bearings.

  • Shell fitment: BSA
