The Visma | Lease a Bike group riders had a brand new time trial helmet for Monday’s stage 1, race in opposition to the clock, within the Italian stage race, the Tirreno-Adriatico. The Aerohead 2.0 made by Giro has a ‘futuristic’, some may say ugly, design. Possibly it’s aerodynamic, however for positive it has prompted numerous feedback, not all good.

“We’re actually trying ahead to driving it,” mentioned head of rider attire for the Visma | Lease a Bike group Paul Martens earlier than the stage 1 TT. “It was an extended street, there have been no limits to the collaboration with Giro. We’re very glad to point out the Aerohead 2.0 right now. You possibly can see from its look that it’s fully totally different from different helmets. It’s a brand new mind-set about aero helmets. We expect we now have discovered an enormous enchancment in our total time trial system. Hopefully we will present that right now.” Martens added. “It’s all the time necessary for a helmet to be protected, however it’s also a part of a system with the riders and the gear. We’ll see!” Effectively, we did see and one of the best Visma | Lease a Bike rider was Jonas Vingegaard in ninth place, 22 seconds slower than winner Juan Ayuso over the ten kilometre race.
Ayuso was the quickest on the day
The brand new Giro Aerohead 2.0 helmet was positively the speaking level of the day and comparisons to Darth Vader and requests for the UCI to ban it instantly attributable to its look and never for any unfair benefit. This isn’t the primary time trial helmet that has shocked the biking group, beforehand there was the Candy Safety Redeemer V2i, the POC Tempor and the S-Works TT5 helmet with its built-in ‘head condom’.
The S-Works
Giro has gone one step additional with the Aerohead 2.0, however as but they haven’t defined how this helmet is an enchancment. The current style for time trial helmets have been on the big aspect, that is to direct the airflow as effectively as potential over the non-aerodynamic shoulders of the rider. These giant helmets clean out the transition from the rider’s head to the shoulders. There’s a hole space on the neck and air can develop into trapped in a vortex, which slows down the rider. This is the reason helmet producers try to information the airflow an increasing number of effectively alongside the torso, with a big helmets. The brand new time trial helmet of the Dutch group takes this one step additional, by not solely being extraordinarily extensive, but in addition protruding ahead. The aspect of the helmet is extensive in order that air flows onto the shoulders and guides the airflow alongside them as effectively as potential. The rear of the helmet additionally suits tightly to the again of the rider to create probably the most aerodynamic move.
The vanguard?
The entrance of the helmet stands out in entrance of the riders head, it’s unclear why, however it might be to make the curve of the helmet on the entrance not so flat. It’s extra pointed than if it sits near the top and has to comply with the form of the top extra. The visor extends to the highest of the helmet on the entrance, whereas on the sides it nearly goes as far spherical because the ears. This shall be to provide the rider as a lot imaginative and prescient as potential. In fact, because of the time trial place, the rider’s imaginative and prescient is alway restricted. Aerodynamics are clearly the primary cause behind the design of this new time trial helmet, magnificence is possibly secondary.
Rudy Mission – Work in progress
Bahrain Victorious additionally had a brand new TT helmet within the Tirreno time trial. The brand new helmet by Rudy Mission can also be giant and, just like the Giro Aerohead, additionally has a large visor for higher imaginative and prescient. However there are additionally some variations, Rudy Mission helmet is extensive, whereas the Giro Aerohead is bigger with the bulging half on the entrance. Apparently the Bahrain helmet is a prototype and never the ultimate design.

The UCI has introduced that it could be conducting analysis into the ‘more and more radical’ time trial helmets. In response to the worldwide governing physique, there needs to be clearer laws concerning helmet designs. As well as, the union banned Specialised’s ‘helmet sock’, as this design is described as ‘non-essential’. The UCI is vital of the brand new Giro helmets worn by Visma | Lease a Bike, but in addition talks in regards to the Rudy Mission Windgream HL 85 helmet, utilized by Bahrain Victorious and the POC Tempor helmet utilized by a number of groups. In response to the UCI, the main target of the event of those helmets just isn’t on the first protecting operate, however on selling efficiency. The UCI additionally mentions the purpose of economic availability. The helmets should be obtainable on the market in line with the laws.
Andreas Leknessund and Uno-X Mobility weren’t neglected
Niels Bastiaens of WielerFlits spoke to Bert Blocken, professor of constructing physics at KU Leuven who specialises in aerodynamics, he sees ‘as much as 5 seconds acquire’ with the brand new Visma | Lease a Bike time trial helmet. From an aerodynamic perspective it’s above all a sensible transfer, mentioned the professor. Blocken was Jumbo-Visma’s advisor within the subject of aerodynamics from 2017 to final 12 months, however he now speaks on his personal behalf. “I used to be not concerned in testing these helmets. Our good co-operation ended on the finish of final 12 months. I’ve moved to Scotland, however am now in discussions with different groups about working collectively.”
Jonas Vingegaard was one of the best positioned rider within the new Giro helmet – ninth at 22 seconds
Blocken is enthusiastic in regards to the time trial helmets of the Dutch group. “The design is, whether or not consciously or not, based mostly on the helmets utilized in pace snowboarding. There they’ve very giant helmets that cowl not solely the top, but in addition the shoulders and a part of the again. The intention of a lot of these designs is to try for a cocoon. It’s a large distinction with conventional time trial helmets, which primarily concentrate on the top, and typically slightly bit on the reference to the again. However right here you’re with a helmet so giant that it encompasses far more quantity than the top itself. This has been round in pace snowboarding for some time. Then you definitely arrive at a reasonably comparable design, with a sort of level on the entrance. A bit area shuttle-like.”
Rocket ship – Dylan Van Baarle
This design just isn’t fully new to biking: “I feel that is the improved, extra refined model of the POC helmet, which EF Schooling First-EasyPost has been utilizing for some time. So far as I do know they had been the primary with this concept. It took fairly some time earlier than one other group arrived. There was numerous laughter about it on the time, it’s in fact noticeable as a result of their design is a bit more paying homage to pace snowboarding. However there may be definitely nice science behind it. It looks as if an excellent thought to make use of this method, and I feel it’s clear that the Giro helmet is predicated on it.”
2nd positioned Filippo Ganna wore a ‘regular’ helmet
The design is quite a bit larger, does this not trigger pointless weight? “I count on not. It’s a skinny shell, it solely comprises some insulation materials, which is shock-absorbing. This manner the helmet stays very mild. What you do have with such a helmet: you’ll really feel that it hinders your head motion. That there are connection factors near the shoulders, near the again. However that’s truly optimistic. It helps to maintain your head within the place it needs to be in in line with the wind tunnel checks. I feel they’ve considered that too, and see it as an additional advantage. It feels a bit stiffer, however in a perfect time trial your head shouldn’t transfer. I noticed on ‘X’ (Twitter) that individuals had been questioning: what about crosswinds? In fact that helmet will catch slightly extra crosswind. However earlier than you actually endure from crosswinds, even when the rear wheel is full (disk), there should be a powerful wind. I don’t instantly see any disadvantages to one of these helmet,” mentioned Blocken.

The expertise remains to be new, however will all main groups must undertake this sooner or later? “That could possibly be. It’s important to get these helmet producers on board. I feel we now have to attend and see what the UCI will do. In the event that they merely permit it, I count on that different helmet producers will progressively leap on board. In fact it takes numerous improvement time. You aren’t going to see that with different groups within the Tour de France. This improvement can simply take a number of years. You additionally don’t need your design to be an identical to that of one other producer. It received’t occur in a short time, however we may even see an increasing number of such helmets. And possibly one thing extra complete.” Blocken doesn’t dare to say with certainty how a lot benefit a lot of these helmets generate. “These aren’t tens of seconds that shall be saved. However it is going to be important. It’s a good step that has been taken, aerodynamically it seems good. It wouldn’t shock me if it may save three, 4 or 5 seconds in a 15 kilometre time trial. That order of magnitude appears life like to me.”
Not everyone seems to be in favour
