Speed without compromise!  The Giro Eclipse Spherical Road Bike Helmet is the fastest road helmet Giro has ever made!  The aerodynamic Giro Eclipse Spherical Road Bike Helmet is Giro's most sophisticated, stylish, and lightweight aero road bike helmet.  The Giro Eclipse Spherical Road Bike Helmet is crafted with spherical technology powered by Mips®, so you can ride with more comfort and an additional layer of protection.

Incremental Gains, Exponential Rewards

Not only is the Giro Eclipse Spherical Road Bike Helmet a big step up from the speed of Giro's previously fastest aero road helmet, the Vanquish, it is the fastest road helmet Giro has ever tested. The Giro Eclipse Spherical beats the closest aero road helmet competitor by 14 seconds over 100 miles at 25mph, and is a full minute faster than our Giro's Vanquish. (Wind Averaged Drag, combination of 80% typical riding position and 20% head down riding position.)
