Built with the same core design principles as the pro-level Zephyr, the all-new Stratus road cycling helmet combines lightweight aero efficiency with cutting-edge comfort technologies. The shape was refined for all-around road performance—ventilated for long climbs but still fast for the flats—and the all-new Float Fit system offers comfort and security with a streamlined fit and an oversized dial that’s easy to adjust with one hand. The Overbrow Ventilation system pulls cool air in through the front and pushes it through an air-channel matrix to reduce overheating. And thanks to the adjustable No-Twist Tri-Glides, the straps stay flat and properly positioned no matter how hard you’re hammering. This model also includes MIPS (Multi-Directional Impact Protection System) for added protection in certain types of impacts.


  • Float Fit - Minimalist, lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments

  • Lightweight Internal Polycarbonate Roll Cage - Composite skeletons used to reinforce helmets, allowing for bigger vents and lighter weight
  • Lightweight Straps
  • MIPS-Equipped - MIPS is a leading slip plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts.
