Limar’s newest lightweight Air Atlas aero road helmet is being raced for its third Grand Tour of the season with the Astana Qazaqstan Team, but now for the first time with an extra clip-on at the Vuelta for free speed gains. The team’s new helmet now includes a unique mini UFO tail cone that can be clipped on to smooth airflow & lower drag, or off for increased airflow & more crosswind stability… Limar Air Atlas vented aero road helmet
From the front and even side, this new Limar Air Atlas looks a lot like a refined evolution of their older Air Speed aero road helmet. But the new helmet steps up performance quite a bit getting faster, boosting ventilation, shedding considerable weight, and improving versatility with its newfound UFO powers. So, what’s new? NACA duct ventilation
Across the mid-section of the aerodynamic shell, both on the sides and top, many modern aero helmets use closed surfaces to keep airflow smooth over the widest & highest points of a helmet.

But the new Air Atlas places 4 new NACA duct vent inlets here (1 on each side, 2 on top) where the inset ramps draw fast-moving air into the shell without disturbing boundary air movement over the helmet.
The new vents connect to 6 internal airflow channels to dramatically improve ventilation over conventional aero helmets, without increasing drag. UFO clip-on tail cone
But then to make the Air Atlas even faster, a new unidentified faster(?) 0bject clips […]
