Why Ride Seven 7iDP?

  • SERT / Energy Reduction Technology: A softer, 4-millimetre polymer foam layer absorbs both linear and rotational impacts, adding protection that goes beyond traditional foam.
  • Conehead / Dual-density foam design: Different foam layers and cone-shaped interlocking zones help distribute force more evenly in a fall, meaning better protection for your head.
  • Certified to the tough stuff: Helmets meet the Australian/New Zealand standard AS/NZS 2063 and international standards like CE and CPSC. Some full-face models go all the way to ASTM downhill racing standards.
  • Pro-tested comfort: Every model gets raced, dropped and ridden hard during development so pads, shell shape, visor and ventilation are tuned for both performance and long rides.
