Sticking my nose in here with a question. Dh has 23cm and I have 25cm tires. I have trouble keeping up with him at the best of times. Do you think a tire change might help even a bit? I'm looking for any advantage I can get...

Interesting about the inflation. We don't have a guage so we have to guess how much air we have. Guess it's time to buy one.

I don't see that it's going to make THAT much difference, I'm not a racer.
Thanks for the Sheldon Brown article.
He seems to agree with the Cascade bike club guy who came to my company to talk about urban biking. He said that most people have too much air in their tires. If a 250 lb man has his tubes at the max inflation of 90, someone like me (125lbs) can do just as well with less air in my tires, and so doing have a more comfortable ride..
