When we set out to design the HERON, we didn't want to create just any road bike helmet. We wanted to create the ultimate road bike helmet! If you think aerodynamics come at the cost of an overheated head and painful neck ? think again! After extensive wind tunnel testing, we came up with a design that directs cooling air over the entire head via deep ventilation channels yet doesn't look or feel too bulky in the process. At only 258g, our aero helmet gives you an extra portion of speed even on long-distance rides, while providing maximum comfort.
