Yesterday I did some aero testing and found that the on me the aerohead is a tat bit faster without the visor. The difference is about .01 to .02 cda between tests at race pace(315 watts) and similarly at sub threshold efforts(200 watts). I found it by accident while riding back to my car after a run. I had put the visor upside down on the helmet and looked down to my wahoo and saw some lower numbers then the runs before that so a did some speed runs with it and got these results.
Have any of you guys found the same?
