The e*thirteen BSA Bottom Bracket allows you to mount your e*thirteen crankset into mountain bike frames with a threaded bottom bracket shell. The lightweight EXA+ aluminum cups house large, custom-sealed 6806 steel bearings that are backed by a 1-year no-questions-asked warranty for good measure. It's compatible with e*thirteen TRS, XCX, and LG1 cranksets with a 30mm spindle diameter only, but will fit both 68mm and 73mm wide bottom bracket shells.
