I was tired when I wrote that Sammy. You are right, roll resistance not wind resistance. Anyways it takes more energy to keep this tires up to speed. I have a set of the Michelin Dynamic tires but want to keep it stock for the test. besides the tires well wear down quick with the high milage I' putting on them. Don't get me wrong the Kanda Kwest are nice tires. But I like the 23c. The Kwest don't come in 23c.

I did a google search to find out how much the Kwest cost. The only size that any ones has is the 700 x 32c. I could only find the 28c on new bikes.
