Yep, chalk up yet another spaceship TT lid for the races towards the clock with the all-new bell-shaped Limar Alien time trial helmet. This one – possibly greater than most – appears to mix all the newest options we’ve seen in aerodynamic time trial helmets. A large bell-shaped frontal profile with an open decrease half. A sculpted aspect profile to hug the rider’s shoulders. Extra (large for TT) open air flow. Plus in fact, a full wrap-around built-in visor held in place with magnets.
However will that make it quicker than the remaining?
Limar Alien huge aerodynamic time trial helmet
Extensive aero appears to be the best way present time trial helmets are trending. The reasons appear to repeat the concept that they do a greater job of spreading clean airflow from the helmet onto the rider’s shoulders and over their again.
The brand new Limar Alien continues on this route. But, it nonetheless easily transitions with a sculpted tail that curves over the rider’s again.
However from the highest view, you possibly can actually see simply how huge this TT helmet goes, after which how shortly it tapers again over the rider. It’s definitely a shorter tail than you used to see in old-school time trial and triathlon helmets.
Designed in CFD however validated within the Silverstone wind tunnel
Limar explains that a lot of their drag-reduction growth and aerodynamic testing centered on bettering efficiency throughout a wider vary of situations, versus straight-on within the Silverstone wind tunnel.
“Along with examinations below very best situations, we prolonged the exams to real looking situations, simulating wind situations generally encountered in time trial highway races, with wind angles various between 5 and 10 levels. These exams revealed that “Alien” significantly excels in these real-world situations, exceeding expectations and delivering even higher efficiency than the outcomes obtained in CFD and wind tunnel exams. This confirms that “Alien” just isn’t solely optimized for very best laboratory situations, however is really tailored to the dynamic challenges of highway biking, providing cyclists an unmatched aerodynamic benefit.”
The result’s an aero helmet that claims to supply all the advantages of the ‘new faculty’ huge strategy, and the ‘old fashioned’ lengthy and curvy strategy.
“On the edges Alien is designed to generate an aerodynamic impact generally known as Outwash, additionally extensively utilized in Components One. This system permits the air that hits the athlete to be deflected, shifting it laterally relative to the determine and away from the shoulders.
The central a part of the higher shell, however, is designed to create and preserve laminar move alongside the rider’s again, due to the Coanda impact. This space works synergistically with the decrease shell, which makes use of the identical precept to scale back turbulence within the space between the helmet and shoulders, and by effectively directing air above them, it feeds the move generated by the higher shell.
The mix of those two phenomena directing airflow ensures decreased drag and optimum airflow across the bicycle owner’s physique, bettering aerodynamic efficiency. This reduces drag and improves aerodynamic effectivity, making “Alien” a really revolutionary helmet in time trial biking.”
In the long run, Limar claims a full 10W drag discount over their already conventionally-aero brief Air King Evo time trial helmet. Permitting the racer to “preserve excessive speeds with much less effort, optimizing race efficiency.”
Tech particulars
This new Limar Alien is fairly standard with regards to development. It makes use of a normal in-mold EPS foam core with a polycarbonate shell over high. It’s simply that the outer shell extends far beneath and behind that common EPS.
Inside the three entrance vents join via recessed channels to 2 high vents within the EPS core. These hyperlink to the air scoop reduce out of the tail of the Alien’s outer shell. Limar’s normal detachable pads and Air Match dial system provide loads of adjustability. And an adjustable webbing straps and a magnetic clasp safe it in place.
The CE & CPSC-certified Alien is obtainable in three sizes: S (53-56cm), M (54-58cm), L (57-61cm). And claimed weights begin at 438g (S), 438g (M), as much as 468g (L).
Limar Alien – Not fairly availability
Just like the Wingdream we featured yesterday, this new Limar Alien time trial helmet isn’t fairly out there simply but. Solely the Astana-Qazaqstan Workforce have them in the meanwhile. However you possibly can join on Limar’s Alien product web page to be notified when they’re able to ship.
When it really hits the market this coming August, we anticipate to see it in white or black variations like Limar’s present time trial Air King Evo helmet. The brand new Limar Alien will add a 3rd overlapping dimension for extra exact matches, though typically conserving about the identical total match vary.
