I really can't see how the aeros can be particularly good
If you could see the aeros, nobody would need to go to Aerocoach :-)
The old Roues Artisanales test had the Cosmic Carbone SL (basically the same as the current Cosmic Pro Carbon apart from some hidden changes to the alloy rim) at about 2W worse than a Hed3 at 50km.h-1
23C, not sure which one. We're talking about MAMIL wheels here, so there's no need to nickel and dime, if it's within 5W rather than only 2W of a Hed3 at 50km.h-1 it's still a pretty quick wheel.
