It's funny you mentioned this because the other reason I went to the dealer was to get an exact clamp-on size for the Campy front der I'm putting on the project bike - the Lemond TdC. It has the carbon seat tube also and measured to exactly 34.9. I assume this translates to 1.37 or 1 3/8.
Should have asked you first and saved the trip. Thanks.
