NEW Kask Valegro Cycle Helmet – GCN’s First Look

NEW Kask Valegro Cycle Helmet – GCN’s First Look


– [Man] We have been lucky
enough to be invited along to the very final stages of aero testing, the brand new Kask Valegro helmet. Which, Team Sky are using
for the first ever time at this year’s Tour de France. Now behind me is the Loughborough University
aeronautics technology wind tunnel. It’s huge, I’ve no idea what to expect from a helmet testing day, I’ve never been to a wind tunnel before, I’m fascinated to find out what goes on. Let’s take a look. (upbeat music) – So we’re joined by Carsten
Jeppesen from Team Sky who’s had a big hand in
the Kask Valegro project. Carsten, when did the project
for this helmet start? – We started talking about a light, really well ventilated helmet
already in the tour 2014. So really from that on, that time on the idea was there and we spoke to our long time partner
Kask about what could we do and looking at different things and, yeah, now finally we are getting there. – This project’s taken almost three years, so is that a typical
length of the projects that you work on with the
team or with the partners? – I can guarantee we are pushing hard but yeah and we would have
liked it a year and a half ago but yeah sometimes things just takes a little bit longer than we expect. Almost every time it
takes a little bit longer, there’s always things that
comes up and we also want to, you know, have we looked at
this, have we looked at that, is it, could we do it a little bit better? So I think it’s our own fault sometimes. – Can you quantify the sort of benefit that a helmet like this
might give on a hilly stage, is it a percent, half
percent, something like that? – Now in the middle of testing we are here at Loughborough
at the wind tunnel today to see where we’re at and I must admit we are a little bit surprised
with the aero part of it, it’s better than we expected it to but obviously there is the cooling effect that has been spot on and
a big improvement, so yeah. – Big benefits. – Big benefits and
obviously weight as well. Carrying a helmet that’s X
amount of grammes lighter for 250k stage in the mountains,
that makes a difference. – So Kask have actually
got a couple of days here at this wind tunnel,
so all that means is that they can test, test, and test again. So behind me they’re just
making a few modifications to the Valegro just to see if it can get a little bit more aerodynamic without losing any of
the cooling properties and without gaining too much weight. And this is a process
that they will repeat possibly tens of times a day
during the testing process. So what can we see on
the screen here, John? – So this is the outputs we get from the CFD simulations
we did of the Valegro. So basically the yellow areas here where the heat transfer coefficient, which is the amount of energy that’s being emitted from the surface, so on this helmet you can see
you’ve got really good cooling around the front of the head, because the head sweats
most at the front, so, obviously humans have evolved
to cool most at the front, but then also at the lower speed it’s important to have cooling
around the back as well. – So it’s an incredibly complex thing with a load of variables.
– Yeah. – At every stage basically. – Yeah lot’s of things to consider I mean obviously first and foremost it’s a crash protection device and that really influences
a lot of the decisions that are taken in the design process. From an aerodynamics perspective you would like to make it thinner. But it’s gotta do it’s
first job, so (laughs). (slow music) – So the brief from Team Sky was to create a super
lightweight cool climbing helmet. And Kask came up with the
Valegro and this is phase zero. So in phase zero, we’ve got
the three hand drawn sketches. From phase one, we go to phase two where we’ve cut down from four potential designs
of the Valegro to two. We then go from phase two
obviously to phase three where again we’ve still got
two potential designs here and then for phase three we go to these and now this is phase four which is the final design
of the Kask Valegro. And actually just over here we have got fresh from the
wind tunnel test study, a mould of the final
design of the Valegro. But why are we even at a wind tunnel if the brief from Team Sky was just to make a lightweight,
cool, climbing helmet? Let’s speak to Kask and find out. So Luca, what’s the answer? – Well the answer is
that we have to consider the speed that Team Sky
athletes carry on climbs which is totally different
from the speed that we carry. And of course also after
climbs there are downhills and between climbs there
must be some flat bits where aerodynamics are really important. And the most important
reason why we are studying the aerodynamics of this helmet is because the final purpose of it is
to be used by a huge amount, hopefully, of people, of cyclists around the world
in any possible condition. – When do you bring this
helmet into the wind tunnel? So we’ve seen all these designs, so from phase zero through to phase four, at which point does it start
getting wind tunnel tested? – Well we want to make sure that when we go to the wind tunnel we have already performed
a bunch of CFD testing, so simulation on a computer. So that we are kind of sure that we are in the right direction, but then the real wind tells
you different things sometimes, so we are ready to modify the shape, to change aspects of the helmet
to improve the aerodynamic, the real aerodynamic in the end. – And is there any real world
testing that you can do? – Yes of course, then the final green light
will be given by riders. So hopefully everything will work out ’cause the time is tight
also in this project, but we’re always ready to modify
anything that is possible. – From the wind tunnel at
Loughborough University to right here in the GCN set, we have got the final
boxed Kask Valegro helmet, and it’s so light that
it’s hard to believe there’s actually a helmet inside this box. But there is, here it is,
the finished Kask Valegro. Incredibly light, it’s
actually very thin as well despite what John Pittman was saying about wanting to make it
thinner for lightweight, heat displacement aerodynamics. This is a very thin helmet, fits very tightly on the head too. It’s going to be interesting to see just how much the Team Sky riders
do choose to use this helmet at the tour this year. Now from the GCN set, back to me, dribbling in a wind tunnel
at Loughborough University. So there we go, an
absolutely fascinating look, it’s quite windy in
here, trying not to cry, at the process of Kask just
optimising their Valegro which is their new lightweight
and cool climbing helmet, and of course because of the speed that
professional cyclists climb at, it also needs to be incredibly aero too. See a video where we explore the benefits of aerodynamics on a climb just click right there, my eyes, and to see a video where we explore the effect of body weight

  1. in the market for a new helmet, this looks good. I've not tried on a Kask but have heard lots of good things.

  2. Is it just me, or does it seem like GCN did their best to create videos that nearly totally ignore the Tour de France ?

  3. looks like an uglier protone.
    not saying that the protone is at all ugly, mind. love it, esp. in solid colourways

  4. I like Kasks helmets, but the one time I actually tried one on, the cushion thingies at the back of the head conflicted really weirdly with my sunglasses. No matter how I adjusted it up/down, couldn't get it to fit nicely :/

  5. And it will cost little more to produce than helmets at the bottom of their range, yet it will still cost between 200 and 300 quid. The markups are extortionate for helmets. No more than £10 to produce (max) per helmet and sold at market for £250. Insane! Oh but wait, what about all that sciencey r&d, wind tunnel wizardry they insist on promoting? Well, what a load of boswollocks that old chestnut of an excuse is.

  6. Hi I'm mark cavendish and here are my top 5 tips
    Tip 1 :get your bike fitted
    Tip 2:lean in on someone and fall over then blame the other person

  7. Saw this on Froome today in the tour. I love my Mojito, but upgrading to a helmet that's still as vented but slightly more aero is super appealing.

  8. I am guessing that handing over the cash for one of these will look like hand fulls of confetti in a wind tunnel. 🙂

  9. Should I buy a road bike, gravel bike or cyclocross bike with road crankset for all year riding and commuting? I'd like to occasionally ride on gravel but I can do without it but would a road bike be too "racey" for commuting? Gravel bikes seem to be a good compromise with the geometry and gearing but don't see too many of them on the markets and they are a bit on the heavier side… #TorqueBack

  10. I guess nobody told you guys that the Tour de France is going on.
    I understand that you have to pay media fees in order to broadcast video, however there's all kinds of things that you can talk about. Like maybe if there was a hugely controversial crash….
    Pretending that the Tour doesn't exist is just embarrassing…

  11. Not sure if I want to buy this or the protone when it becomes cheaper… The Valegro looks somewhat like the Spesh Prevail, but I'm sure it will be better and lighter. Also I'm currently running the old Infinity model and wanting of a lighter upgrade.

  12. 3 years to develop a styrofoam hat ?! I wonder what that thing is going to cost. The new 'Mavic' shoes cost $1200 ? Fortunately there is a lot of choice out there.

  13. Clearly the wind tunnel model is based on Froomey's riding position: face down and never looking up the road.

  14. I noticed pretty much the whole Sky team in this new helmet today in Stage 5, all but Geraint Thomas, he was still rocking the Protone.

  15. Nice. But I would need my head examined for forking out the dough for it.Are there custom sun glasses (not visors) offered by helmet manufacturers to compliment the aero effects (transition) from head to face.

  16. Hi GCN! i am a cyclist. i feel guilty when i am passing someone when i am at my walking pace or attack pace. how to pass them courteously or respectfully?

  17. 1:32 – "it's important to get this measurement right. We will put it into our propriatory Sky algorithm and find out whether this particular specimen is GC material"

  18. was expecting Lasty to appear on the last part of the video on a superman costume (worn by Matt on the "what not to wear" video). 🙂

  19. Ultra Ugly helmet. Mushroom shapes are so so ugly, the mojito is till the best looking kask helmet, it's got a nice shape and not flat and ugly like the others!

  20. Interesting to see how a company takes an idea from a conception to reality. I was surprised at the amount of time it has taken to get to this point…

  21. It's got a really daft smiley face right in the middle of the front venting. It can't be unseen once you've seen it.

  22. Watching in the early am hours …but, – @6:20 I can't stop seeing a "little blue face" lol! Right now where I ride I'm dodging masses of beetles that would go right in that "mouth". Now I need to go watch the race to see if they are wearing it.

  23. I've been going to Loughborough Uni for three years, and always wondered what the big fan noises behind the engineering were!

  24. How about a segment on what brands of helmets fit what shape heads. I ordered a Kask and couldn't get it to fit. I had the same issue with motorcycle helmets. I have a long narrow skull, so helmets made for round heads (Kask) won't fit. Short of going to shop and trying helmets ad nauseum there's no way of knowing which manufacturers accommodate which shape heads, round, oval, long narrow. Would make a great video.

  25. As everything it seems to have gone full circle, and looks a bit more refined. I'm sure it will sell though being the latest model. To be fare I own a Kask and do rate them as being one of the best out there.

  26. Will it have leather straps? Vegans won't buy leather and there are a lot of vegan cyclists

  27. Weight reduction and wind tunnel test but no crash test. It seems like the companies forgot the actual purpose of the helmets.

  28. maybe they should do some investigating in paint choice… black and dark colored helmets are great sellers but they don't cool your head as good as a bright color or white.

  29. The Protone is really comfortable (for me) but there is nothing like enough ventilation for a sunny day in Spanish mountains. Of course, you have to move at a reasonable pace to get any air through vents, so perhaps that's my problem.. Once this comes down in price, I might look at one for hot days instead of the Mojito. It is good to have this option because the Prevail is not the right shape for my head. The question I have is: how does the ventilation compare to the Mojito, which is now so cheap?

  30. Honestly, which helmet I get is almost purely on head shape. Rounder vs more oval or "Asian vs European" head. I really love the protone but its definitely a bit more oval than say the Mojito.

  31. Its a pity they are so expensive/ Im so poor! I helped Kask stop people selling fake copies of their helmets – but still didn't get a free helmet for thank you! #eggshellsnomore!

  32. Fun fact: the glossy white color in size medium (U.S. version) weighs 250 grams. The anthracite matt color weighs just 205. Less paint.

  33. looks really good but they need to make some better color options, the colors they offer now are pretty funky looking.
