Performance-focused open-face trail helmet

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.

  • 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 XT2® 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

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

To measure the head size, place a measuring tape around the head just about an inch above the eyebrows.

Small 51cm - 55cm 20.08" - 21.65"

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