Enduro bearings are designed and built to last, but unfortunately sometimes some of the parts that surround them can still wear out. This light-contact silicone seal is the same outer seal that comes with Enduro bottom brackets for SRAM GXP cranksets that feature the custom MR 2237E extended race bearing to provide additional protection against the elements.
