Agreed, we can't make a blanket statement without knowing more about the shifting system, as Athena was redesigned from 7 speed Syncro to dedicated 8 speed in the early 1990s. If it has Syncro levers, we'll need to know the freewheel and/or lever insert. Only if the levers are dedicated 8 speed, do we know they they will work with 7 speed SIS compatible freewheels. There are also three possible derailleurs, all with different capacities, that will affect the freewheel gearing options.
