The lightweight yet resistant RSR 10 adjustable retention system provides perfect personal fit. thanks to its wraparound structure and multiple micro-metric vertical and horizontal positions for the size adjustment.

In-Mold technology allows us to cast the external polycarbonate outer shell directly during the injection stage of the expandable polystyrene (EPS) impact-absorbing foam. The result is a much more rigid structure which is knock-resistant and extremely light, allowing for better ventilation system. The combined action of the EPS structure, the polycarbonate cap and exo-skeleton creates resistance to the mechanical action exercised by an impact and dissipates the energy in order to prevent it from being transferred to the head of the person wearing the helmet.
The airframe frontal padding minimizes the sweating process inside the helmet enhancing the air circulation and avoiding the release of unpleasant smells and ensuring the best level of performance.
Just replaced my Sterling helmet with this one. Can’t be happier. I’ve had 3 Sterling helmets over the years and it was time to upgrade. Looks great and light weight. Feels faster. The only thing is that I wish it had the mesh net lining to keep the bugs, bees and pebbles out. The fit is good.
Beautiful helmet. Perfect fit. Highly recommended!
I had an Cannondale helmet. I used this helmet new on 70.3 IM and felt the difference. Good fit light keep head cool. Even improved time.
I wore this helmet in IM Madison and was so aero fast on the downhills the wind tunnel around my skull just propelled me forward and I took 3rd place in my age group!! Thankyou Rudy Project for rushing the Nytron helmet to me for race Day!!
The large eyeshield on the Wingdream is great for being able to see everything in front of and around you. Riding into the sun was anot a problem, though Id really like some lenses that are more mirrored (for esthetics).
Putting this on in T1 was super easy too. All my old aero helmets have been tight and difficult to get my ears in without damaging the helmet a little after years of use, this one goes right on without any interference. The buckle takes a bit of practice to get, but is much easier than the classic one once you're used to it.
After buying a couple of repair parts for my 23-year old Rydon's, I got notification from Rudy Project that there was to be a factory warehouse moving sale. Desperately in need of a new helmet, I spied the Protera+ in my size at a fantastic price. I didn't need to be told twice and bought the helmet without any further consternation. Showed up super quick. I've used the Protera+ 6-8 times now. It feels like it was made for my head. I couldn't ask for more.
