Even more curious about that now that they've released the SRAM version.

On the one hand, this is some of the dirtiest air on the bike, with the leg and shoe and rest of the drivetrain causing turbulent air and reducing the cost of exchanging aero for friction at this particular point.

On the other, creating clean separation and allowing the air to resume clean flow is desirable. We can't know without independent data.
