I just received a nice Hetchins frame from Graham Drummond by way of Hilary Stone. (Thank you very much to both!)
The installed BB is marked Campy Mirage and doesn't have an adjustable cup, so I guess it's a cartridge-style BB. Does this BB have sealed bearings and there's no point in removing it [because it can't be greased or adjusted]? And does it have the same taper as 70s Campy crank arms?
