The Apidura Aero Bolt-On Top Tube Module is a strapless performance pack designed for competitive gravel racers looking to improve aerodynamic efficiency. Developed through Computational Fluid Dynamics analysis, it smooths airflow behind the stem to provide an average 5 watt saving when paired with the Aero Frame Module.
Constructed with ultralight Hexagrid fabric and internal HDPE reinforcement, this module maintains its shape without deforming. It features a fast-entry magnetic closure for quick access, carbon fiber plate mounting, and 5 cm of fore-aft adjustability for a precise fit.
