Helmet
ABUS TimeShifter
ABUS's TT and triathlon helmet developed with Swiss Side, optimised for low drag across four realistic head and arm positions rather than one perfect lab pose. Both sizes share the same outer shape, and it is the first TT helmet with two interchangeable visor shapes (Narrow and Wide) to tune its effective width to the rider's shoulders, plus a cut visor for very low positions. Replaces the GameChanger TT 1.1.
