APIDURA - Aero System

A modular frame and top tube system that enhances aerodynamic performance, integrating with your bike to make you faster.

The Aero System is a performance-oriented solution for competitive gravel racers, developed through rigorous Computational Fluid Dynamics (CFD) analysis. With an average 5 watt saving at race speed, it’s wind tunnel tested and race-proven at the highest level, showing a benefit on every bike we’ve tested. View the data.

The Aero System was designed with the primary purpose of improving aerodynamic performance, regardless of what you decide to pack. For years we’ve helped riders go further, now we’re helping them to go faster. Learn how.

– Modules work together to improve aerodynamics
– Transfer panel technology reduces drag
– One-handed fast entry to top tube module
– Soft interior base protects contents
– Ultralight Hexagrid construction

Specifications

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.

We recommend using our Frame Pack Sizing Tool to check the fit before purchase.

As a rough guide, the L/XL side is best suited to bikes sized 56-58cm and above. The S/M is best matched to bikes from 52-56cm.
