Hi all have found another bike to play with - a mid 70's Olive green Grand Prix, missing pedals, seat and tyres everything else original - as far as I can tell.
Will post pics when I pick up but in the meantime I need some advice on chains & freewheels as they will undoubtedly need replacing at some point.
Am assuming it has English threaded Normandy hubs so are there any decent new manufacturers of freewheels and chains that work together that I can keep buying as needed? Will have to do the same or similar set up for the international when that's finished too.
Do I have to go nos for everything (which I want to avoid because it's unlikely to find a reliable source) back in the day all the half decent chains and freewheels worked with Campagnolo or simplex derailleurs so never had a problem running an Atom / Regina/ Winner etc freewheel and Regina / Reynolds etc chain.
Concerned more with robustness over weight reduction and consistency.
Are all new chains narrower and therefore prone to wear compared to the standard chain for a 10 speed bike back in the 70s?
Does anyone make a standard robust chain these days or are they all narrow to suit up to 7 speed cassettes?
Brands - KMC? Wippemann?
Same for modern freewheels do they distinguish between English and Italian threads?
Brands? IRD? Sunrace? What are these like?
Thanks in advance!
