right then just stripped out the BB from the 70’s BSA Prima and cleaned and degreased. The cups look ok and the axle tidy enough but Might as well replace the caged bearings I’m thinking before assembly ......however, there’s no identifying mark to say what size they are....anyone help with that please?
Cheers
Edit NERVAR 121 is stamped on the axle
