Apidura Aero Top Tube Module

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

The Aero Top Tube Module is a performance-oriented solution for competitive gravel racers, developed through rigorous Computational Fluid Dynamics (CFD) analysis to smooth airflow behind the stem and improve aerodynamic efficiency.

Combining with the Aero Frame 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

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 Tensions Bands work together to eliminate gaps between the frame and stem, passing air smoothly from the front of the bike across the modules.

RACING SERIES

Designed for the specific demands of ultra-distance competition and audax.

APIDURA

We’re an independent, family-run business of cyclists, makers and problem solvers, brought together by a shared mission to find better ways to explore the world by bike.

Apidura was born from necessity; pioneering ultralight, rackless packing systems to help us take our love of cycling further and allow riders to unlock their instinct for adventure. As devoted adventure cyclists, we design with our fellow riders in mind, creating products that address genuine needs and bring new value to the bikepacking scene. We create the best packs we can, using technical materials and precision crafting techniques – and when we find a way to improve them we do so straight away and without fanfare. We don’t do ‘seasons’, limited editions or discount our gear – we simply create the best possible technical bikepacking gear that’s built to last.
