I recently bought myself an old Peugeot Tourmalet to renovate as a project. All the parts on it are decent but it badly needs new tires. The bike has the original Rigida 27 x 1 1/4 rims and I've been wondering what is possibly a very stupid question:
I have a new-ish racer that I've been cycling for the last 2 years and it's fitted with much narrower, racing style tires which I prefer both the look and feel of. I'd quite like to put something similar on the Peugeot to modernise it a bit as the tires that are on it at the moment are quite large and bulky in comparison. The bike in question has 700c rims and my question is, does this have an impact on the width and style of the tires?
Could I swap the wheelset onto the Peugeot or does this require a massive amount of adjustments? Or is it possible to buy a slimmer, more modern style race tire for 27 x 1 1/4 rims.
Sorry, I'm sure this is a very obvious question but it's easier to ask here than be scoffed at by a local bike shop!
