Speedfil Z4+

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.
