A strapless, aero-optimised top tube pack that integrates seamlessly on your bike to make you faster.
The Aero Bolt-On 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
