Limar’s latest light-weight Air Atlas aero highway helmet is being raced for its third Grand Tour of the season with the Astana Qazaqstan Staff, however now for the primary time with an additional clip-on on the Vuelta at no cost pace beneficial properties. The workforce’s new helmet now features a distinctive mini UFO tail cone that may be clipped on to clean airflow & decrease drag, or off for elevated airflow & extra crosswind stability…
Limar Air Atlas vented aero highway helmet
From the entrance and even facet, this new Limar Air Atlas seems so much like a refined evolution of their older Air Pace aero highway helmet. However the brand new helmet steps up efficiency fairly a bit getting sooner, boosting air flow, shedding appreciable weight, and bettering versatility with its newfound UFO powers. So, what’s new?
NACA duct air flow
Throughout the mid-section of the aerodynamic shell, each on the edges and high, many fashionable aero helmets use closed surfaces to maintain airflow clean over the widest & highest factors of a helmet.
However the brand new Air Atlas locations 4 new NACA duct vent inlets right here (1 on either side, 2 on high) the place the inset ramps draw fast-moving air into the shell with out disturbing boundary air motion over the helmet.
The brand new vents join to six inner airflow channels to dramatically enhance air flow over standard aero helmets, with out rising drag.
UFO clip-on tail cone
However then to make the Air Atlas even sooner, a brand new unidentified sooner(?) 0bject clips onto the again to morphs this aero highway helmet within the route of a time trial helmet. The clip-on UFO tail cone solely seems to increase the general size of the brand new Air Atlas by a couple of centimeters at most, nevertheless it extends the teardrop form behind the riders head the place turbulence is understood to create numerous additional drag.
The quick design is a compromise in smoothing out turbulence, whereas limiting potential tail cone downsides like: crosswinds instability, elevated drag from riders transferring their heads round, additional weight, or limiting air flow. We’re possibly most curious what the UCI guidelines must say about it although, as they aren’t followers of detachable aerodynamic cowls or actually any non-integral element added only for improved aerodynamics.
For now, it seems just like the UFOs the workforce is utilizing are 3D-printed components, so possibly they’re racing below a growth technical exception and must use mounted components sooner or later?
Past the brand new aero form, new aero NACA vents & utterly new UFO cone, the Limar Air Atlas can be an excellent gentle helmet at a claimed 220g (S), 235g (M) & 260g (L). That comes from a fairly advanced 3-part in-mold polycarbonate shell over hollowed-out EPS building.
The 17 vent helmet (7 entrance + 4 NACA + 6 rear) sticks with standard washable interior pads, a brand new much more adjustable Air Match Evo dial retention system, gentle webbing straps & a Fidlock magnetic buckle.
Limar Air Atlas helmet – Pricing, choices & availability
The brand new aero highway helmet is formally a MY23 product and isn’t on Limar’s web site but, so we anticipate it to be accessible no sooner than this coming winter, and even into early spring 2023. However when it does come quickly, the Limar Air Atlas will promote for 260€ in three sizes (S 52-56cm, M 54-58cm & L 57-62cm) and in six commonplace colours.
Plus, most certainly an Astana-replica, possibly within the new subdued white & blue the workforce are racing at La Vuelta a España now.
