Speedframe MIPS Helmet

Outfitted with MIPS technology, the Speedframe Pro is just as sleek, stylish, and protective as the original, but with the added help of reducing rotational forces in the event of a crash. It has an easily adjustable multi-position, goggle-compatible visor for changing light conditions, and a 360-degree fit system that dials in an exact fit. And being the Pro version, this helmet's Varizorb dual-density EPS liner ensures a comfortable fit, while the XT2 antimicrobial comfort liner provides freshness at the end of the ride.

  • Open-face mountain biking built for comfort and speed
  • Varizorb dual-density EPS liner absorbs harsh impact
  • Removable, washable XT2 liner fights funky odors
  • Multiple vents promote a cooling airflow
  • MIPS technology reduces rotational forces in a crash
  • 360 Fit System dials down just the right level of security
  • Three-position, adjustable visor is also goggle-compatible

    My Fave (along with the Pro version)

    I've put it through the wringer
    Size Bought
    6` 1"
    197 lbs

    Cannot say if this runs true to size, cuz I'm not a helmet size expert (are there even?..) but I ordered a LG and a MD, expecting the LG to fit, and ended up keeping the medium. It's perfect! In every way, for most applications. I use it every day, and on some pretty extreme gnar, to boot. The trick to sizing is to fully loosen the adjustment boa, then place it on your head and it SHOULD feel slightly loose; then you fasten the boa to your liking. This thing actually looks cool, and it's the first helmet I will never ride without. The babes swoon when I roll out with my Speedframe.


    I am not seeing the weight(s) of these helmets - Sorry if I'm missing that spec but I would think it is a critical question with helmets, is it not ? Thank you in advance for your support.
