This bike is now mine - thanks bulldog!
I've now fitted a Brooks saddle, mudguards, front and rear racks and bottle cage from my previous bike, and given it a good going through:
Next step is to replace the 6 speed freewheel with a 7 speed one, so I can fit my 7 speed bar end shifters. I'll also put aero brake levers from the same era on there. I also need a pair of good tyres, as the ones on this are perished, and eventually, I'll upgrade to a triple crankset. When I was younger, I always wanted a Dawes Galaxy. Now I feel I've got something that little bit more exclusive!
