Performance-focused open-face trail helmet

We're celebrating our 50th anniversary with a collection of gear and apparel that is a nod to both our past and our future. The Speedframe Pro Blocked Helmet earned Virginia Tech’s best rating (5 stars) in its Bicycle Helmet Ratings program. Designed with input from our pro mountain bike athletes, this top-tier open-face mountain bike helmet offers a market-leading feature set including Mips®, dual-density EPS to bump up impact protection, a 3-position and goggle compatible vision, plus a FIDLOCK SNAP buckle for easy on-off. Add this piece of our history and heritage to your life and celebrate with us as we continue to push boundaries into the next 50 years of performance products.

  • Mips® added protection system has been proven to reduce the rotational motion when implemented in a helmet by absorbing and redirecting energies and forces otherwise transmitted to the brain
  • Dual-density Varizorb™ EPS provides improved protection by spreading forces of impact across a wider area
  • FIDLOCK SNAP helmet buckle provides quick and secure entry and exit while wearing gloves
  • Removable, washable Ionic+® liner is antimicrobial and manages odor while wicking moisture away from the head
  • Optimized venting with channeled, in-molded EPS provides efficient cooling
  • Goggle-compatible, 3-position adjustable visor
  • 360° Fit System allows you to dial in your perfect fit, every ride
Size
  • Sizes: small, medium, and large (see size guide for measurements)
How to Dial Your Fit
  • 360° Fit System - counterclockwise to loosen, clockwise to tighten - allows for a precisely dialed fit. Adjust while wearing the helmet
  • Back cradle: four points of adjustment move the cradle up or down your head to ensure the best fit possible

For care instructions see our Helmet Care Guide

Note: Avoid exposure to aerosol sprays like bug repellent and sunscreens as they can cause your helmet's finish to peel

Materials: 41% EPS, 20% nylon, 31% PC, 3% polyester, 5% POM
