      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 Evolve version of MIPS is designed to bring this tech to a wide range of helmet types.

      Features

      Quick and Easy Fit

      The elastic band in the Sidestreet helmet makes it even easier to get the right fit. It automatically adjusts to the contours of your head as you move around, keeping the helmet stable, comfortable, and in its optimal protective position.

      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.

      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.

      Fixed Visor

      A sturdy fixed visor helps keep the sun and rain out of your eyes – because you never know what the trail, or the sky, will throw at you.

      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.
