Aerfast.5









Aero Race fork
The 80mm wide, striking fork of the Aerfast.5 is bulky and aggressive. Aerodynamically optimised, it generates less air turbulence and offers a high degree of smoothness and stability.

Perfect symbiosis of aerodynamics and lightweight
The new seat tube and the revised seat post including aerodynamic seat stays give the frame a real race look. The AERFAST.5 combines aerodynamics and weight optimisation like no other bike - track records are guaranteed.

IMPROVED STIFFNESS
Even more liveliness and acceleration speed thanks to improved stiffness in the bottom bracket.

Faster than ever before
The Aerfast.5 was born in the wind tunnel. For the first time, a drag of just 195 watts* was measured. This makes it the fastest racing bike tested in a wind tunnel! In addition to its outstanding aerodynamics, the Aerfast.5 is a lightweight. The frame made of high-quality carbon fibres weighs a sensational 890 grams, making it even lighter than the previous model.
*According to measurements by the GST Gesellschaft für Strömungsmesstechnik based on the TOUR wind tunnel test without water bottle cage and with a sporty 120mm x 360mm handlebar stem unit.
