Road Helmets or Performance cycle helmets offer unrivalled levels of protection with the absolute minimum of material. They are extraordinarily light and feature a series of huge vents, designed to scoop up air and direct it over your head to keep you cool. On long, hot climbs, the difference is noticeable. Since more advanced helmets began being used in the Tour de France, carbon fiber inserts have started to be used to increase strength and protection of the helmet. The Giro Atmos and Ionos, as well as the Bell Alchera were among the first to use carbon fiber. Some modern Aero racing bicycle helmets have a long tapering back end for streamlining. This type of helmet is mainly dedicated to time trial racing.
All helmets sold at Fatbirds meet BS EN 1078:1997 standards, which is identical to the EU standard, and which replaced BS 6863:1989 in 1997
