any tunnel data on the evade? There are several twitchers in here who don't think it's aero.............
And they would be wrong. I published my findings on that helmet last september. 5w slower than the McLaren, which is pretty amazing.

hardly cheap or fast. pretty much ultimate fail.
1. Stop PMing stupid comments, troll.
2. The McLaren is 5w faster than the Evade.
3. The Giro A2 often tests faster than the McLaren.
1. The McLaren is 5w faster than the Evade *FOR ME.* That's definitely not universal. Helmet selection is hugely dependent on back choice.
2. Based on what data? I'm not saying that you're wrong (or right). I'm just saying that in a thread talking about my actual data from an actual wind tunnel, your statement, "the Giro A2 often tests faster than the McLaren" doesn't really mean very much.
- how often?
- on how many different riders?
- in what tunnel?
Just to take one data point - Crowie is *NOT* under contract with helmets from Specialized. That's why he always paints them up with Road ID logoing. So if he wanted to race in the Giro A2, he could. It is the helmet he wore in 2011, before the McLaren was released. But he doesn't; he wears the McLaren. Why? BECAUSE IT IS FASTER. By about 2min over 180km (roughly 5-6w). Based on his own PUBLIC data:
http://triathlon.competitor.com/...ro-helmet-test_63574 So, based on that data - which supports other data if you want to go googling:
- The McLaren is faster than the A2
- The A2 is not even clearly faster than the Evade (this based on Specialized's own testing), and the Evade is lighter and better ventilated than the A2.
You can even just search this forum for more data. Jim @ ERO has some good numbers from the Evade. It's definitely the fastest aero-road helmet, besting both the LG Corse and the Giro Air Attack in their testing as well.
If you want to make the statement that the A2 "often tests faster than the McLaren," you can. But back it up. Often - to me - means that at least 50% of the time, the A2 is faster. What does it mean to you?
