The Speedfil Z4 Water Bottle 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 ports are strategically placed allowing for multiple positions and variable angles accommodating most aerobars.
- Direct Aero Mount: 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.
- Versatile: The Z4 is lightweight, easily configurable and can be used on any front, frame and rear saddle mounts.
