Do you lose the 2 large vents in the front when the visor is up?


EDIT: Is the vertical switch in the middle a vent at all? I can't tell from the photo's on the website.

The 2 vents are about 2/3 blocked when the visor is up. Fully open when the visor is down.
The vertical one is fully open when the visor is down.

How does the large size compare with other mfgr's sizing? I have a very large skull. The largest Bell size works for me, but when I picked up a large Catlike Whisper, it took a lot of work with a sanding block before I could even get my head into it, and it is still tight.

Dux_Helm

Find out the size of your Bell and Catlike.

Our L will be 58-64cm.

You forgot about the giant vent between the riders forehead and helmet.
That is closed with the visor down and open with the visor up.
I bet that with the visor up, it creates a negative pressure zone and more air is able to suck up and over the rider's head this way.

Dux_Helm

Well, I cannot claim with full confidence that alot of air flow that gets into the space between the rider's face and the lens actually travels further through the helmet and out the back.
But I can say the breeze on the rider's face is pleasant, the amount of wind in the eyes is enough to keep the rider comfortable and prevent fogging, but not too much, so rider's eyes should not water.

A new review just came out:

Here's a first hand review by Emily Zinn:

im still skeptical. ill need to see one in person. wake me up when somebody invents carhartt tough, fully waterproof and breathable courier knickers for 100 bucks and then ill get excited....

banerjek

I'm also skeptical, but this idea is no worse than a lot of others and it's certainly better than the roundtail bikes.

My concerns would be airflow (lenses up is obviously impeded, but even down might be an issue) and how clean/scratched lenses get in normal use (particularly in bad weather), and level of protection they provide -- I've had some decent sized things hit my lenses pretty hard and am a bit concerned about the amount of open space.

The anti fogging is not a particularly big deal for me since I only wear vented lenses so that's not an issue. I suspect cleaning would be a bigger pain than with regular glasses. I wouldn't be surprised at all if people bought these, but I suspect regular glasses are a better fit for me.

Duxhelm needs to sponsor a team or more riders because, no matter what people say, it lends credibility.
People will have theoretical bias based on looks alone but if they see pro-level riders racing them, then it's all good.

I think a team of guys at the head of a peloton would pay for itself in sales.

I would seriously consider this if you can wear these over prescription glasses. I hate having to keep up with sunglasses and regular glasses - having the shade part integrated into the helmet would be one less thing to try to find a place for.

tagaproject6

Indeed!

Dux_Helm

I agree with you.
Hopefully by next spring we will have a few riders.

For now, only my friend Seth Wells is our sole rider and guinea pig

He is a 20+ year veteran competitive XC racer , and loves the helmet.

Especially since he won both BC Cup and (first time ever) Provincial BC Championship.
He has been wearing our helmet all season, and had the best season of his career..
Am I taking full credit? ...well....I SUPPOSE his hard work played a small role too ...lol

I saw your write up in VeloNews as well.

Dux_Helm

That Velonews review must have been quite popular, i got quie a few inquiries the day it came out- both end customers and dealers.

Dux_Helm

So about a month ago these guys from Culprit Bikes got a helmet from us.
Now I know why they wanted one:



Here's the product review, it's their aero bike with discs:

First off, i wanna say that Idea is pretty cool, better than a lot of others Ive seen recently (as bannerjerk pointed out already) but...

beyond the novelty and coolness aspects what real advantages does this provide? Whats the hook? Ive ridden with the helmet/sunglasses combo for years and I dont have any of the face irritation or fogging issues that this may address.

Simply put, (not trying to be a smartass) what makes this better than my current setup that would justify a ~$200 purchase?

cruiserhead

I see all kinds of advantages. The integration seems especially attractive for commuting and being aero on the road.
I have a feeling Giro and others can't wait for that patent to run out!

It's nice to see it in the video of a "road racer" in action with it.

youcoming

Can you wear glasses under it? I don't like contacts after a night shift.

VeeDubOne

Agree on this. Great idea indeed, especially if executed well (which you seem to be intent on, based on your feedback solicitation) but i am struggling to see the cost-benefit. But this being biking, the coolness and the small convenience factor itself is enough pbly for many to drop a couple of hundred? Whats the compelling motive? Not being critical, just trying to understand the key draw here.

tagaproject6

Depends on the frame of your glasses.

cruiserhead

What is the compelling motive of buying a $250 Giro Aeon over a $90 Giro Savant?
What about the $240 Giro Air Attack (which has a lens too, but not retractable)?

Lawcheehung

Aeon is 18g lighter and better ventilation

my bell furio was around $50 (280 gms) and my rudy project graals were $60

I will try to answer to the best of my abilities:
Real advantages:
Our lenses do not fog up.
Sweat will not get on the inside of the lens.
upper face area is nicely ventilated, while keeping the eyes protected.
Quick release lenses mean you can keep your eyes covered in all riding conditions.
Sports oriented prescription glasses can be worn under it.


My personal experiences:
I have prescription glasses with photochromic lenses.
With that and the lens combo, I never have to fumble with 2 pairs of expensive glasses.
With the clear or amber lens in place on a rainy day I never have to worry about my glasses getting wet or muddy
The lens covers a broader area than sports lenses, keeping the upper face protected from flying debree, bugs etc
THere is no gap on the top.

THe lens does not fog up.

My sponsored rider/guinea pig - Seth is a XC rider.
With my lens in place he can see where he's going all the time.
With his races even photochromic lenses are not always the best, as they go through patches of sunny/dark areas quickly.

He rides his races usually with clear glasses on, and either grey or amber lens on the helmet.
That way - in anticipation of a dark area he can flip the lens up, while keeping his eyes protected.
He does not have to wait for a photochromic lens to loose it's tint - which in many situations is too slow, by the time it brightens up, he's back out in a bright area.

This combination helped him to ride faster with more confidence (his words). He shaves minutes off his race times and places better.

This is clearly visible, especially this season, as he started winning races he has not won before.
He also got to the top on provincial level - BC Cup championship and Provincial Championship - first time in his career.

This may sound like a sales bull$hit, and it's hard to convince anybody over the Internets, so the best thing is to simply try.

Talk to your bike stores, get them to contact me and buy at least one or two helmets.
Than try for yourself - it will work for some, will not for others.

But Seth willingly uses my product as his only lid - considering he has a good collection, that is saying something.



p.s. Seth is not on this forum, but if anybody posts on Pinkbike forum, he is under Sethwells.
Feel free to contact him for first hand experience.
