This bottom bracket shell is designed specifically for the SRAM PF30 bottom bracket. The outside diameter is 2" by 74 mm wide, providing 1 mm for facing after welding. The inside diameter is supplied .5 mm undersized, to 45.5 (1.791"), and must be finished to size after fabrication by the frame builder. Machined from 6/4 titanium, it is relieved in the center for weight reduction to 47.24 mm(1.860").
