They got the 17watts in a super disingenuous way. They listed in a single place (likely to make it less obvious) that it was in comparison to the tubular version of the xxx wheel. As tubulars are much slower than clinchers both aerodynamically and rolling resistance wise (then add in using narrow tubulars on a bad road surface vs 25 or 28mm tires), they can easily inflate those numbers by making a ridiculous comparison.

I really do wish they came out with white papers again. Trek had a history of great white papers old Aeolus D3, Aeolus XXX, gen 1/2 speed concepts, and three madone versions. I feel that they stopped writing white papers as if they presented results truthfully, the gains would be so small that no one would buy new equipment.
