Description
The Apidura Aero System is a racing frame bag & top tube bag combination designed to be as aero-dynamic as possible.
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 Apidura tested.
The Aero System was designed with the primary purpose of improving aerodynamic performance, regardless of what you decide to pack.

Sizing Advice from Apidura:
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 size is best suited to bikes sized 56-58cm and above. The S/M is best matched to bike sizes from 52-56cm.
