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.

Versatile: The Z4 is lightweight, easily configurable and can be used on any front, frame and rear saddle mounts.

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 (included). No additional mount or hardware is required.

The Z4+ is specifically designed to be used in conjunction with the Speedfil A2. This package includes a non-slip strap that locks your A2 in place and prevents the system from rotating.

Also included is a uniquely designed tube clip that secures the drink tube to the side of the bottle and completely out of the wind.
