Ha ha. Within the first 5 seconds it was obvious that the test was fundamentally invalid. The fastest road clinchers? Seriously? No tubulars were tested, which are obviously the fastest. Apart from inconsequential training rides, every pro is on tubulars during every stage in every race.

This test is like doing a performance road test with the following auto fleet:

• 1985 Yugo GV
• 1975 Trabant
• 1976 Chevy Chevette
• 1978 AMC Pacer
• 1961 Corvair
• 1970 AMC Gremlin
• 1971 Ford Pinto

Let's pick the weiner!

And in the real world, wheel/tire combinations with the lowest rotational inertia are the fastest. Tire frictional losses are tiny, and aero doesn't matter much if you are drafting 95% of the time. Having to deal with hundreds of accelerations per ride - this is where performance gaps occur.
