Piaw, thanks for taking the time to measure! Although I have been a customer of Rivendell since their inception and was a Bridgestone rider previously, I would like to support them as much as possible. However, I find it frustrating that they don't list frame tubing specs. I understand there are many reasons why they would not do so. But, as someone who would be buying a frame from out of state, sight unseen, it's a tough sell. As you rightly suggest, the only way to know how it feels is to ride one.
