The question is, what did you do with gears?
Because they looked rather good for retro kit, the suntour shifters for instance, they are the best non shimano/campag shifters you can get hold of, they work with anything, they have a form of micro click indexing which makes them easy to use, and was that rear mech an old Campag?
Its a nice fixie, but I think it would have been an equally nice retro ride
