I think I remember reading off the website racedaywheels.com that they claim a 1080 back wheel is more aerodynamic than a disk wheel at 0 degrees of yaw. I’m curious, can anyone explain to me why disks seem to perform better at increased yaw angles?? I think I also remember that the zipp sub9 performed best at 15degrees of yaw…is this some kind of sail effect? How does it actually work? Would a wheelcover act the same way in that it performs better at increased angles of yaw? And why would a 1080 be faster than a disk at any degrees of yaw?
And please don’t respond with “0 degrees yaw never happens in the real world” because I’m very aware and I’m just asking how the physics works…it appears to me that a side wind would create a huge eddie of low pressure beside/behind the disk wheel…just curious. Thanks in advance.
