I have been given an old 10-speed I am thinking of conerting to a fixed gear bike.
Before doing so I'd like to know the make on it.
I'll answer any specific questions but here is what I have found:
Front and rear shifters are Shimano, ditto with the hubs.
derailleur cables are anchored to bolt-on cable stops.
Crankset arms have 'Tracer' cast into them.
I know Centurion made ProTour-model bikes on the late 70's-early 80's, but I can't find the Centurion brand anywhere on the bike.
I couldn't find any reference to a Protour bicycle manufacturer so any ideas would be appreciated.
