Product description

Absolute freedom in the wilderness: every athlete deserves a comfortable and lightweight helmet, even under extreme strain. Valegro, developed in collaboration with the INEOS Grenadiers team, offers extreme lightness and top-notch ventilation, even on the most demanding climbs and the hottest roads.

The polycarbonate shell profile of the VALEGRO has been tested and refined by KASK engineers in conjunction with a wind tunnel to achieve the best possible results in terms of thermal cooling. VALEGRO offers advanced ventilation and an impressive weight of just 180g (small size). This new design offers maximum cooling thanks to 37 vents with new breathable and quick-drying padding. The 5 mm layer of fast-wicking, three-dimensional, thermoformed padding is antistatic, bacteriostatic, regulates heat and transfers moisture using Resistex Carbon material. In addition to this cutting-edge technology, the chin pad with its eco-leather strap also contributes to all-day comfortable helmet wear.

OCTOFIT: The rubberised Micro Dial adjuster provides improved finger grip. Floating cradle contact points combine internal gel pads for optimum comfort. These supports are designed to oscillate freely through 180° allowing a perfect fit on any shaped head. The Skeletal Brackets of the cradle have been designed and refined to provide the best fit and support whilst being as light as possible.

Main advantages and parameters:

  • OCTOFIT: The fastening system allows for finer adjustment
  • Hyvent: The helmet's construction is designed to maximise airflow and thermal regulation
  • Reflective graphics increase rider visibility
  • Weight: 180 grams (size S)
  • Certification: CE / UKCA - EN 1078
  • Padding material: 87% nylon, 9% polyester, 4% other fibres
  • Strap material: Faux leather
  • Surface finish: Glossy or matte
