SRAM Road Bottom Bracket with Angular Contact Bearings

This is meant for threaded road frames, 68mm, English threading. Enduro ACB (angular contact bearings) are an improvement over radial bearings as every ball is in contact with the races during load. This spreads the force of pedaling across a larger surface area which in turn decreases friction and helps minimize wear. Dual lip groove seals made of silicone help keep water and other contaminants out.
