Alpinestars Supertech R10 Solid Helmet

Outer Shell:

• Utilizes molding technology with a multi-composite combination featuring a 3K high-density carbon outer layer, a uni-directional carbon composite layer, an aramid fiber layer, and a fiberglass one
• 3K high density carbon outer layer provides strength and efficiency of energy dissipation over the shell
• Layered composite combination created by bonding everything together with an epoxy resin already applied on the pre-preg fiber, perfectly controls the ideal proportion of resin versus fiber to maximize strength, mechanical performance, and lightweight providing improved energy management, as well as limited outer shell deflection, making the energy spread wider and better absorbed by theEPSliner

Inner Shell:

• Eight-piece multi-densityEPSliner with six specific densities that are strategically positioned in different zones to ensure excellent energy absorption from impact forces dissipated over the outer shell, as well as a close and comfortable fit Four inner shells construction is optimized to ensure riders have the correct fit, which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an impact
• Linear and oblique force management TheEPSinner surface is smooth, creating an optimized, low friction area, for superior oblique impact management
• To help fight and mitigate rotational, oblique, and linear impact forces, the inner surface of theEPSliner was designed with a low friction surface polished to be smooth and specially coated to reduce friction even further, allowing the comfort liner to move against theEPSthus allowing the riders head to move independently inside of the helmet, or vice-versa, which can significantly reduce the amount of force transmitted to the head, neck, brain, and spine from an oblique impact, while simultaneously reducing the possibility of a concussion
• A-Head Fitment System Allows the helmet to be tuned exactly to the riders preference by having the ability to adjust both the height and angle at which the helmet sits on the head
• TheEPSis fitted with the A-Head Fitment System that allows for a specific setup that can be adapted to how deep the riders head sits in the helmet, as well as how far forward or backward the helmet is tilted

Aerodynamics:

• Developed withCFDsimulations, validated in the wind tunnel and on the track, the
