An aero-optimised Frame Module that enhances aerodynamic performance, integrating with your frame to make you faster.
The Aero Frame Module is a performance-oriented solution for competitive gravel racers, developed through rigorous Computational Fluid Dynamics (CFD) analysis to minimise drag within the front of the frame and create a seamless aerodynamic profile, regardless of what you pack.
Combining with the Aero Top Tube Module creates an average 5 watt saving at race speed, validated through wind tunnel testing and race-proven at the highest level, showing a benefit on every bike we’ve tested. View the data.
For years we’ve helped riders go further, now we’re helping them to go faster.
SIZING
The Aero System is designed to integrate with your bike to deliver an aerodynamic benefit. As such, the available sizes relate not to the capacity, but to the size of bike that is best suited to deliver this benefit.
As close fit is essential in order to see optimal aero benefit, it is recommended to use our Interactive Sizing Tool to check the fit.
S/M - Recommended for sizes up to 56cm
L/XL - Recommend for sizes 56-58cm and above
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.
