Shimano Dura-Ace BB-7710 Track Bottom Bracket
Shimano Dura-Ace BB-7710 Track Bottom Bracket Info
The Shimano Dura-Ace BB-7710 Track Bottom Bracket is built specifically for the demands of track racing — a dedicated unit designed for use with the Shimano Dura-Ace FC-7710 Track Crank, and nothing else. The chrome-moly steel axle and Octalink splined interface create a rigid crank-to-spindle connection that resists the flex that comes with explosive, single-gear efforts on the track.
Where this bottom bracket separates itself is in the bearing arrangement. A compound structure combines ball bearings and needle bearings within the same unit — needle bearings to manage radial loads, ball bearings to handle axial loading. Each type does what it does best, and together they support the spindle with a durability that's designed to hold up under sustained, high-power output.
