It seems the ones on the bike I just purchased are loose, especially the drive side, quite a bit of play between the body and spindle so it does not look good. By the way, the dust cap is round with no visible means of removing it, are they pressed on? I would like to keep this Lejeune ( posted elsewhere ) original so any suggestions, perhaps a different Lyotard model? I am surprised they lasted so long, they look to be in pretty good shape otherwise, I would swear a few ball bearings are missing the way it feels.
