Abus Gamechanger TT 1.1 Helmet BSS-002829 - Serviceable design with spannerAbout Abus Gamechanger TT 1. 1 Helmet Aerodynamics is on a new level: Because every watt counts, we have further developed the GameChanger TT time trial helmet. When it Comes to Watts The lightweight GameChanger TT 1. 1 brings optimised aerodynamics to the track so that you don't lose a second. This is ensured by the flexible and soft EVA tail at the rear of the helmet. It prevents air turbulence between the neck and helmet from slowing you down.
