AlpineStars storm into the market for race helmets with their multi adjustment helmet. Size Medium is available for one lucky winner to obtain. RRP was £1299 plus customs charges from the Italian Manufacturer. Only 200 Helmets were produced for the whole world to try to get a hold of. A lot of us tried with the best internet connections but did not succeed. Now is the chance to own one for less than £15. 2 interchangeable spoilers included Multi adjustment inside for head angle for best comfort and visibility. Developed in their Asolo R&D helmet department, which formed in 2011, the S-R10 has been five years in the making. Starting from a clean sheet of paper MotoGP legend Andrea Dovizioso had a hand in its development and uses tech from their motocross helmets, first used by Alpinestars’ sponsored riders in 2018 before going on sale in 2019. The S-R10’s shell is a rigid composite structure made up of four layers designed to work together to absorb and dissipate the force of an impact. It has a 3k carbon outer layer and beneath is a uni-directional carbon composite layer, an aramid fibre layer and fibreglass layer. They’re all bonded together with the kind of advanced epoxy resin also used for carbon car racing chassis. The lower edges of the sides are also raised and fitted with soft rubberised sections for collarbone protection. Riding in a Alpinestars Supertech R10 helmet Inside the shell is an EPS (expanded polystyrene) liner formed in eight sections with six different densities to suit where they’re needed around the helmet. The EPS is smooth coated to let the fabric interior slide, to reduce the rotational acceleration to the rider’s head in an impact – sort of like a MIPs system. Cheek pads feature an emergency release system and the helmet strap is secured with stainless steel DD rings. A sturdy metal lock secures the visor to stop it lifting or coming off in a crash and the quick release visor mechanism is also metal for maximum strength. Alpinestars have created four shell sizes to optimise fit and weight: XS-S (53-56): 1490g, M (57-58): 1540g, L (59-60): 1590g, XL-XXL (61-64): 1645g. Racing helmets have evolved to mimic the shape of racing cycle helmets in recent years to help them slip through the wind. The S-R10 has a similar teardrop profile with a design evolved from Computational Fluid Dynamics simulations and time spent in a full-size wind tunnel using Astars’ own Moto2 machine. The helmet comes with two interchangeable open-backed rear spoilers: a short one for the road and a longer one designed to work with the hump on a leather suit, which reduces drag by an extra 4.45%. The S-R10 also has side wings and even the top edge of the visor is sculpted to smooth airflow. Alpinestars says its new helmet keeps the rider’s head more stable in a race tuck, hanging off and sat upright. The reduction in wind buffeting reduces fatigue and strain on the neck and head. Will be the best helmet you ever have. Durable materials guarantee less degradation over the years
