The Abus Gamechanger TT 1.1 helmet brings optimised aerodynamics to the track. This is ensured by the flexible and soft EVA piece at the back of the helmet, which prevents air turbulence between the nape and the helmet from slowing you down. Thanks to the multi-position aerodynamic design, you can also tilt your head during the race without suffering significant aerodynamic losses.And to ensure putting on the helmet takes hardly any time, you can snap the Fidlock magnetic buckle under your chin in the blink of an eye. You can also easily attach or remove the visor with the magnetic fasteners. There are three visor variants available: Transparent with clear lens, smoked with tinted lens, or mirrored in a chrome variant.
