About This Product: White Industries External BSA Bottom Bracket

The White Industries External BSA Bottom Bracket at J&R Bicycles is constructed from U.S. sourced aluminum alloy with two bearing options to fit your style. This lightweight, high-performance BB sits outboard on the frame's BB shell instead of inside the shell for efficient power transfer and added durability. Be sure to check with the manufacturer of the crank you are using to find the allowed OBW, or Outer Bearing Width, to ensure compatibility.
