Even if you cut Trek's numbers in half, it still seems significant. I still struggle to believe the numbers when you see so few racers choosing aero bikes. I get that extra watts don't translate directly to results, but they can certainly contribute.
Keep in mind, that is for the total SYSTEM. Bars, stem, seatpost, wheels, frame.
How much of that could you get from a normal, "round" tubed frame with a set of aero handlebars and 50-60mm wheels? I'm not going to hazard a number, but I'm guessing it would be a good portion of that difference.
