APIDURA Aero Frame Pack Module S

The Aero Frame Module is an aerodynamic frame bag designed for gravel racing. Its shape, developed using CFD analysis, integrates into the front of the frame to reduce drag and maintain an aerodynamic profile regardless of the contents. The transition panels at the down tube and the contoured upper section minimize gaps between the bag and the frame. When paired with the Aero Top Tube Module, the setup achieved an average saving of 5 watts at race speed during wind tunnel testing conducted by the manufacturer.

The ultra-lightweight Hexagrid construction combines a high-strength nylon grid with a TPU lamination to achieve a lightweight and stable structure. An internal HDPE thermoplastic reinforcement provides rigidity and helps the bag maintain its shape, while the soft internal base protects the contents. The narrow profile reduces the risk of knee contact while pedaling and sprinting.

The mounting system includes two silicone-coated Hypalon straps with a locking mechanism, a Velcro panel attached to the down tube, and low-profile tension straps around the head tube. The non-slip silicone coating helps limit bag movement on the frame. The main compartment is accessed via a zipper located on the drive side, while a cable port allows for connecting or charging a device while riding.
