The Speedframe Pro Defy helmet was developed with input from our professional mountain bike athletes and has rightfully earned the highest rating (5 stars) in Virginia Tech's bike helmet rating program. This premium open-face mountain bike helmet offers a host of market-leading features that provide protection on every trail ride. At the top of the list is the MIPS® Air Node Protection System, a lightweight helmet that reduces rotational movement and directs forces away from the brain in the event of a fall. The dual-density EPS Varizorb™ further enhances impact protection by spreading impact forces over a larger area.
The BOA® Fit System allows micro-adjustment for a perfect fit on every ride. Ionic+® lining is antimicrobial, anti-odor and wicks moisture away from the head. It can be easily removed and washed. The visor can be adjusted with one hand and is compatible with both sunglasses and goggles. The helmet also has a special solution for storing sunglasses. If you're looking for a performance-focused trail helmet, then congratulations - you've just found it.
