      IntelliVent Cooling
      Taking ventilation to the next level, the IntelliVent system integrates maximum airflow into every one of our helmet designs without compromising protection. Because cooler heads prevail.
      MIPS Air Node Protection
      MIPS stands for Multidirectional Impact Protection System, and it means a better helmet. Able to dissipate rotational impact in certain types of crashes, it'll give you peace of mind on every ride. The Air Node version is the lightest MIPS design available.

      Features

      PolyRail Structure

      The PolyRail system doesn’t just give your helmet a distinct look. It also reduces weight, reinforces the structure, and amplifies our IntelliVent air-flow system, making it a better helmet all around.

      FrameLock Gripper

      The FrameLock eyewear grippers on the front vents of Dynam make sure your glasses stay in place when stored on a ride.

      ErgoFit+ Dial

      Those last few millimeters matter. The overmolded ErgoFit+ adjustment system means you can precisely dial in the perfect fit, with micro-adjustability of the diameter of the helmet’s 360 degree retention harness.

      BioMap Fit

      Born from understanding that no two heads are alike, BioMap Fit was developed to ensure proper fit on nearly any dome. We designed special shaping and coverage so that our helmets feel and fit like no other, and sizing is consistent across the range.

      Fidlock Closure

      Once you try Fidlock, you’ll never want to own a helmet without it. No more fussing with traditional tiny clips. The Fidlock closure system uses magnets to click the clips into place, and then it pops open only when rotated in a specific way.

      Smart Construction

      It’s called in-mold construction, and it bonds the polycarbonate outer and foam inner layers of the helmet into one solid piece. It’s how all Cannondale helmets are made. What’s that mean? A stronger, smarter, lighter helmet.

      Remove, Wash, Repeat

      Don't worry about sweating too much. The removable pads can be taken out for drying, washing, or replacing if you want to start fresh.
