Haven't done the poll as I mainly ride a mountain bike and that does not apply. This summer I got my first road bike and it came with 700x26's and that is what is still on the bike. No discomfort so may go to 23's when they need repalacing.
But on the Mountain bike I used to fit Conti Grand Prix slicks on the 26" wheels. In comparison to a 700 tyre- This is about a 22. They take high pressure (110psi) and roll exceptionally well. They Have lasted well but have to admit that the sidewalls are showing a few too many tears in them for me to trust now- Reckon they have done about 3,000 miles in the 6 years I have had them and other than the sidewall damage- still work fine. (They are relegated to the Wall now as If it is road work- the shiny new bike gets used.)
