I agree. Carbon has a lot of advantages and that is certainly one of them.

I understand the builders desire for secrecy but unfortunately without the data the buyer is acting on faith in the builder and vague language about stiffness. A few years ago I had an email conversation about their tubing specs with an owner of a major metal tandem maker. I had bought one of his bikes but he would not tell me, an owner, the wall thickness of the tubing I owned. It was a cordial conversation in which he explained that it was a marketing decision based on their desire to prevent buyers from comparing bikes based on tube set. Basically they wanted to turn the process into a black box where the buyer's decision is limited to faith in the dealer's opinion of what bike is best for the buyer. Since that time they have changed position and publish enough information on their web site to determine the bikes tubing specs.

For me it tubing disclosure comes down to labeling. I think car buyers should know engine the car has. PC buyers should know what processor and how much memory. The most important spec of a bike frame is the tubing used. For example: if I were to order a Calfee I would like to know the stiffness of the tubing they plan to use so that I can compare it to the stiffness of the tubing on the Calfee bike that I test rode. Maybe Craig Calfee would share that with a buyer if were he asked, I don't know since I have never asked him. Certainly most buyers aren't interested in those details and just want a good bike to ride.
