Is that a 34.9mm clamp? I recently purchased a Carbon Covert and read that although the seat post is also 31.6 like your bike, the clamp is actually 37mm on the stock bike. I would like a Deity clamp and was wondering about the sizes available.
Yeah mine is a 34.9.....looks like the carbon version does use a 37mm according to the Transition site. If you have access to a metal lathe, you can easily bore one out to fit, I have a buddy that has a lathe and he's done a couple seatpost clamps for me like that.
