The Apidura Aero Frame Module is a performance-oriented frame bag developed for competitive gravel racers and riders chasing every possible aerodynamic gain. Designed through rigorous CFD analysis, it minimises drag within the front triangle and creates a more seamless aerodynamic profile, regardless of what you pack. On its own it is built to improve integration and airflow, and when combined with the Aero Top Tube Module it delivers an average 5 watt saving at race speed. The construction balances speed, stability, and practicality. Transfer panel technology reduces drag, the soft interior base protects contents, and the ultralight Hexagrid material keeps the overall structure light while maintaining strength. Internally, an HDPE frame reinforces the shape to avoid deformation, while the drive-side zip offers easy access to a single main compartment with an optional internal lash loop. It is a highly considered aerodynamic storage solution for fast gravel racing and long, high-speed efforts. Key features Aero-optimised frame module developed through CFD analysis Designed to minimise drag within the front of the frame Average 5 watt saving at race speed when paired with the Aero Top Tube Module Transfer panel technology to reduce drag Soft interior base to protect contents Ultralight Hexagrid construction with internal HDPE reinforcement Technical specifications Storage: single main compartment Internal feature: optional internal lash loop Closure: zipper on drive side Attachment: two silicone-backed Hypalon load straps, Velcro transfer panel, rubber tension bands Reinforced structure: internal HDPE thermoplastic frame Weight: Medium 205 g / Large 235 g Size & fitThe Aero Frame Module is sized according to bike size rather than carrying capacity. Medium is best matched to bikes from 52–56 cm, while Large is best suited to bikes sized 56–58 cm and above. Care & washing instructionsSpot clean only. Stains can be treated with concentrated dishwashing liquid, and zippers should be cleaned and lubricated regularly with silicone or petroleum-based grease. Abrasion is not recommended.
