I have a 1949 Claud Butler frame with 114mm dropout spacing. The original spec of the bike states it was available as 3, 4 or 5 speed, although Sheldon specifies this spacing as only suitable for 3 or 4 speed. I have not been able to find any hubs at this OLD, except track hubs that would normally be used with single sprockets. Does anyone know if these hubs would take a 3 or 4 speed freewheel or were there special hub designs for multi-gear set ups? I've searched the usual forums but haven't been able to find a definitive answer.
