Got it the week be IM CHATTANOOGA and had it dialed in after one ride. It was only mid-80's out, but the vent worked well.
It is wide, and the air flows really good, out of the all aero helmets Rudy has, this is the best.
Now the strap isn't the best to lock without looking at it, I wish I could change it.
The way my head is, I can't fit it all the way inside the helmet, I was praying my entire Ironman race that I would not crash because I didn't feel safe with the way the helmet fits- it is not wide enough- , and it is very strange since I always loved the Rudy helmets since they fit incredible for me.
To spin the **** is extremely hard almost impossible.
I wish it would come with other shields color or a case protector.
I wore this helmet in IM Madison and was so aero fast on the downhills the wind tunnel around my skull just propelled me forward and I took 3rd place in my age group!! Thankyou Rudy Project for rushing the Nytron helmet to me for race Day!!
