Speedfil Z4 Cage is the first cage optimized for BTA (Between-The-Arms) aero hydration.

Garmin® Integration.

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.

*Garmin® Quarter Turn Bike Mount (Part# 010-11430-00) sold separately.

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.

The ports are strategically placed allowing for multiple positions and variable angles accommodating most aerobars.

Z4+ Features:

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.  This provides the rider with a greater aerodynamic advantage compared to other systems with a fixed mast.
