I'm currently upgrading an old Peugot frame and I'm trying to buy the correct wheel size for the bike. This is actually my second attempt after selecting the incorrect size last year. The bike is old and uses cantilever brakes and i'm trying to identify the correct width, I'm 90% confident it will accept a 700c.
The big question I'm struggling to know is the width the wheels should be. I made a massive mistake and brought 700 by 13 - ridiculously thin. I'm know hearing anything between 19 and 27 but I'm not sure what to check so I can determine the correct size.
I'm also looking for a single gear.
Any ideas what the average wheel width should be for a vintage Peugot bike?
Here are some more details on the bike:
