That you do (negligibly) more work with a (slightly) heavier bike over the same course at the same output and/or pace isn't really being disputed. What's being disputed is "you get a better workout on heavier bike." The only thing that determines whether one gets a better or worse workout is the person pushing the pedals. Unless, of course, these guys are spinning their 53/11 @
100+ rpm over their entire ride on their "light" bike and they need the extra kilo to, uh, slow 'em down, I guess.
