ExAero MAG Bottle and Cage System

Positioned precisely where the front-wheel wake transitions into the down tube and seat tube zones, this isn’t just a bottle cage, it’s an aerodynamic component.

Traditional round bottles are simply attached to the frame. The MAG, by contrast, is engineered to actively guide and condition the airflow through this critical area.

Compared to two conventional round bottles (Ø74 mm diameter), the dual MAG system lowers weighted CdA by 0.0047 m² — equivalent to a power saving of approximately 5.49 watts.

Note: Sold as single bottles, please purchase both bottles for the full system.
