If you push the limits of downhill speed and big air, the S-Works Dissident is for you. That's because it's the lightest, most-ventilated, and technically advanced carbon fibre full-face mountain bike helmet out there. To help make sure of it, our 3D sculpted cheekpads and 4th Dimension Cooling System keeps things airy in the heat, while the Carbon Matrix shell keeps it light enough for all-day comfort.
Our new ANGI Crash Sensor gives you and your loved ones peace of mind like never before—when combined with our iOS or Android app, the sensor will detect a crash and send a text message to specified contacts in your phone. It also syncs with our app and STRAVA® to provide GPS-based activity tracking.
