Yes, Alpha One is genuinely faster. Not by much. Our CFD studies show it to be about 7-8g faster on average (across a variety of stack heights and setups). This translates to a savings of about 1 Watt. In the wind tunnel, it is very difficult to detect a difference that small, reliably. It takes good CFD to really test differences this small. Alpha One vs Alpha X might look like a wash in the wind tunnel. Our goal with Alpha One wasn't to make a significant aero savings, as Alpha X is already a VERY fast bar. Our goal was simply not to make Alpha One slower than its predecessors, so that it wouldn't be a compromise to utilize its exceptionally-flexible fit system. And we succeeded. It's consistently faster than Alpha X in all the configurations we tested. The reason we were able to get away with a shorter airfoil section on the base bar wing is not a simple story to tell. Suffice it to say, we tried a LOT of shapes for the aerobar wing. Some were very deep, more like Alpha X. Yet the deeper wing sections did not make a faster complete bar. There are lots of little interactions where the wing meets the stem, transitions into the top and sides of the stem and Monopost, etc. The shallower 3-to-1 sections worked better at preventing those little interactions from getting messy and creating drag on this particular system.
