The new patent pending Speedfil Z4 Cage is the first cage optimized for BTA (Between-The-Arms) aero hydration. The Z4 Cage works with standard water bottles, as well as the Speedfil A2 to offer several unique and distinct advantages.
The Z4 is lightweight, easily configurable and can be used on any front, frame and rear saddle mounts. The Speedfil Z4 Cage is designed with numerous ports for a direct BTA mount into the aerobar extensions with a minimum of 4 nylon zip/cable ties. No additional mount or hardware is required. The ports are strategically placed allowing for multiple positions and variable angles accommodating most aerobars.
The Speedfil Z4 integrates a detachable arm which can hold a Garmin® Quarter Turn Bike Mount* to the top of the cage when used in a BTA configuration. This not only saves precious space within the aerobars but also provides easy access. Data is now where it should be - easily viewable and easily accessible.
