asked by: a guest Will this bearing fit any Mega Exo bb
anwered by: canteau FSA has used a couple of different sizes of bearings over the years with this one being the most common one for the MegaEXO-19. The bearing size is stamped on the rubber dust shield. As long as yours is marked MR087 you should be good to go. These bearings will not work with MegaEXO cranks that have a 24mm spindle.
