I did a test Feb 5 in the A2 wind tunnel in Mooresville, NC. I tested the Wingdream on my Argon TT bike vs my four year old Giro Aerohead. The test was a wash, no advantage for either helmet. Obviously I was hoping to get quicker with the Wingdream. I’m a M75 USAC racer and have raced over 20 seasons winning numerous local TTs for my age group and several National Senior Games Golds. I’ll try the Wingdream in a couple early season races as I believe my vision is better but I don’t believe it has an aero advantage based on the tunnel test results.
