Regarding the 8-9 watt difference between the wing dream and the old aerohead, I think its worth noting, that in the below test he did from 10 months ago, one of his riders compared the Aerohead (older as well) to the Wing Dream, and it was a tie.
Go to 16:00 in the video…
Wingdream looks like it fits the first video rider much better on the back than the second video rider. That’s probably what made the bigger improvement. I have the older giro aerohead and my training buddy that I race against uses the wingdream. I would love for the aerohead to be faster because I really don’t want to spend $500.00 on a new helmet. I will say that his wingdream helmet is a ton lighter than my aerohead.
Just ordered a WingDream after seeing this video. Excited to save some watts in Cozumel.
I had an Aerohead and I found visibility much better in the Dream as well.
At the beginning and throughout the video Jim say’s these results are specific to this rider. he could not be more clear.
Absolutely. But still tells everyone to just buy the rudy…
