After having built a few bikes recently that had 27 inch wheels originally with both 27's and 700c's. I have come to the thinking that on a lot of C&V bikes just ride better with the original correct size wheels and tires exspecially if you can keep close to the original gearing. Fooling around with different setups I have ridden both of my current C&V bikes a 620 Jeunet and 64 Gitane with both nicer 27 inch alloys and correct size 1 1/4 tires and nicer 700c with good modern 25 tires. Both bikes ride significantly better with the correct size 27s. Neither does a good job of tracking riding no hands with 700's yet both track good to great with the correct 27's. I wanted to find out if people here agree or disagree with this?
