SIZING

AERO OPTIMISED
Developed through extensive CFD analysis and wind tunnel testing, the shape of the Aero System smooths airflow around the bike, reducing drag and making the rider faster for the same effort. The Aero System has shown a benefit on every bike we’ve tested.
The Aero System was designed foremost as an aerodynamic system. Whether run full or empty, it makes your bike faster.
INTEGRATED DESIGN
When the system is mounted, elements such as Transfer Panels, Skirt and Tension Bands work together to eliminate gaps between the frame and stem, passing air smoothly from the front of the bike across the modules.
