The Prestacycle System 500 Aero Pack rethinks traditional under-saddle storage with a rigid, streamlined 500 mL storage system designed to fit cleanly beneath and behind the saddle.

System 500 combines secure storage with an integrated mounting solution for popular bicycle radar systems. Choose the Aero Pack Door that matches your radar, or select the Blank Door for a clean storage-only configuration.

A rigid aluminum saddle-rail mounting system with a GoPro-style interface keeps the Aero Pack securely positioned without the movement and sway of a conventional soft saddle bag. A full-size removable rear door provides easy access to the entire storage compartment.

Inside, an included soft bag organizer and foam pieces help organize, secure and quiet tools, inflation equipment and other ride essentials.

500 mL storage. Up to 500 g recommended cargo. Integrated radar mount. One clean system.
