The ABUS TimeShifter delivers measurable aero benefits  for different positions, conditions and rider types.

Developed in collaboration with the industrys leading minds. Designed for anyone who wants to stay one step ahead. Demonstrably more aerodynamically efficient.

Developed in collaboration with Swiss Side, the TimeShifter was created on the basis of transparent data, extensive testing and measurable aerodynamic performance. The result: a time trial helmet that delivers significant aerodynamic advantages across all selected test configurations.

Speed is relative
Developing a time trial helmet is an enormous challenge: aerodynamic performance depends on many factors  from body measurements and riding position right through to race conditions. That is why there is no single helmet that is the fastest for everyone  the choice is highly individual. A model that delivers top results for one athlete may perform very differently for another.

That is why ABUS have deliberately chosen not to make blanket aero claims. Instead, the TimeShifter was tested, compared and validated through an iterative development process:
112 CFD simulations
194 wind tunnel tests
39 velodrome measurements
The result is not a helmet designed for a perfect laboratory position  but the most high-performance ABUS TT helmet to date, designed to suit the widest possible range of riders and racing situations.
