Rudge Sports, Robin Hood 3 speed, Hercules touring, a fleet of big black lugged city bikes
Is there no date on the SA hub? The only two speed SA hub I can think of is an obscure automatic hub,or some pre-war hubs for sporty bikes http://www.sheldonbrown.com/sturmey-archer.html not the sort of bikes that had rod brakes. Or might it really be a 3 speed hub? What sort of shifter does it have? a thumb shifter or top tube mounted shifter? Any pics you could post?
