I have a B'TWIN Triban Aero rear wheel and am trying to replace the sealed bearings. After removing the end caps and a DS rubber seal I can see the ends of the bearings, at this point I assumed that the axle could be removed by tapping with a hammer, however with a reasonable amount of force it didn't move. Do I just need to be more aggressive or is there a further step before the axle and bearings can be removed from the hub?
Nathan Knutson is right!
