This seal has a side that is more heavily coated with rubber than other (blue). This side should contact the bearing cover of the Megaexo bottom bracket. If the bearing covers on MegaExo bottom bracket have a lip on the inside edge, do NOT use this seal.

Rated 3 out of 5 by Anonymous Blue plastic seal on metal washer
Fits on the drive side spindle, 24mm ID. Designed to stop grime entering the dust cover but I've shredded 2 of them. The blue plastic comes off in a ribbon after not much use. Used on FSA Energy cranks and others.
