Enduro Bearings Bottom bracket gasket Enduro SRAM Non Drive

SE MR 21537 AL 6061 - Bottom Bracket Seal SRAM GXP - 21.5mm x 37mm Bearings Enduro are designed and built to last, but unfortunately some of the parts around them can still wear out. This light contact silicone gasket is the same one supplied with Enduro cranksets for SRAM GXP cranksets that are equipped with the MR 2237E extended race bearing to provide additional protection from the elements.
