Product Details

Bottom bracket seals are specific to the spindle size of your bottom bracket, not the “style” of bottom bracket (i.e., BSA, PF30, T47 etc.).  The seals should sit directly against the bearings, with the part numbers (molded into the seal) facing out.  Any spindle spacers used should sit on the outer side of the seal, between the seal and crank arm.
