Evade. Vs Giro Advantage 2

Triathlon Forum
1

Hey folks,

I have a 70.3. Race coming up and I still have not made a helmet choice

I already own a white Evade and Giro Advantage 2.

If it’s a super hot day I will go with the Evade. But does anyone feel that one helmet is that much better then the other over a 70.3 course with 2000 ft of elevation gain?

Love to hear the input

I have both. I just got the Evade and will never again use my Giro Advantage. That thing is going on ebay! Evade is supposed to test faster from what I understand and less penalty when your head is moving around. Only downside of Evade is too vented on cold weather days…froze my head for the first 2 hours of IM Tremblant!

I have read that the A2 is likely faster for most people. I also have both and have not work the A2 since purchasing the Evade. Things I prefer:
I can actually hear while wearing it - this makes me feel more safe, as I am aware of my surroundingsLooks betterEasier to bring to racesI can wear it with a backpack, so that means I can ride to TransitionEasier to put on in T1 (this is like a 2 second difference)More comfortable
Unless I see data that the Advantage2 is measurably and significantly (to me this would mean 5+ watts) faster, I will not wear the A2 again. These benefits are worth 5 watts to me. They are not worth 10.

Paul,

Thanks for the info in the Evade
My next question is now did you place you helmet sticker over the vents?

Paul,

In my last race I had a three digit number and was able to cut around the number so the entire number was visible AND the vents were not partially blocked. I am assuming if the vents are partially blocked the helmet gets slower. It would be interesting if someone from specialized can confirm, because if this is not the case, I would tape all the vents up for cold weather races. I think the virtual frontal of the helmet is slower with vents open. To confirm this I looked at airflow with head up and head down. In each case they engineered for unencumbered air pass through.

Ultimately you’d have to test to know which was faster for you and by how much. I’ve seen enough tests to know that I’d choose the opposite of most people who chimed in.

Dev what size is your A2? i’ve got a friend looking for a M. PM me if you want are serious about selling it.

Brian, mine is a small. I ride mainly head down thus the Evade tends to be better all purpose for ME. As you said, you need to rest personally though with some field testing etc.

Thanks but bummer as he needs a size up.

I wouldn’t be fooled by the head down argument with the A2 vs the Evade, you might (probably) are still prolonging your day with that choice.

REI has them for $123 right now during their Labor Day sale.

what about the evade vs the giro air attack? these are the two helmets im torn between.

OK, I thought Rapp had put up some data (or maybe MITaerobike) saying with head down the Evade was faster. Having said that, I also appreciate that they are both Specialzed guys, but I respect when they make statements they are almost always based on measured facts/data.

Do not block the vents on the Evade. See this video where they test that:

In that situation you should not be torn at all. Go with the specialized.

For 10 riders the Evade could be slower vs A2 in heads down by 5-10w for 6 but for 4 riders 3-8w faster. (just choosing #'s)

When it comes to helmets unless you test their facts/measured data do not = you and what it’ll do for you. It could be much worse or much better.

I wouldn’t really trust someone else’s data until it’s at least N=10 or more and even then you’re going to be choosing based on the trend line.

2, 3, 4, 5 are of no consequence.

Individuality reigns supreme in the wind tunnel, but I have plenty of data that shows the a2 is easily that much faster than aero helmets, let alone road helmets.

I had the Giro and picked up an Evade in time for this year’s IM Cairns (thinking it would be another stinking hot day … ha!), as well as thinking ahead to doing Kona and wanting a cooler helmet than the Giro.

I love the Evade over the Giro so much that I’ve now sold the Giro and have two Evades - one for racing and one for general riding/training.

On the question of race numbers over the vents, I had no problem doing some creative cutting with a pair of nail scissors so the sticker folds into the vents and the number is still visible.

thanks for the advice

Thanks. I’ll do some more field testing on a local downhill in still air (trees on each side) with a variety of head positions. That’s likely my best option.

Let us know how that goes. OK? I planned on doing the same on a 2 mile stretch of downhill road with no intersection not too far from here. Surrounded by trees. I have a Giro A2. Been looking at stubby helmets for a while. Evade and Air Attack. (How does Air Attack compare?)

BTW Spec has an Evade Tri on their site. No availability. Magnetic clasp seems to be the only difference.

AA tests, on average, worse than the Evade.

But none of you seem to be particularly concerned with trends in wind-tunnel data.
