product description
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, the Speedfil A2 and has several unique and distinct advantages.

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

The Speedfil Z4 Cage is designed with numerous ports for a direct BTA mount in 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 GarminŽ 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 is should be - easily viewable and easily accessible!

*GarminŽ Quarter Turn Bike Mount (below) is necessary to mount Garmins to the Z4 and Z4+.

Bottle launcher

The basic idea behind this cage is right: to put a Garmin where it should be. The Z4 fits nicely on my Cervelo P5. The Garmin arm could have been placed more forward, but one gets used to the slightly rear position pretty quickly. My issue is that the cage doesn't hold a regular bottle very tightly. I installed the Z4 so that the bottle faces forward - as it should for easy retrieval. With just a few bumps in the road, as I was climbing with my hands in the bull horns, the bottle was launched... in mid race... This happened twice!. Not s much an issue when one is in the extensions - the hands can hold the bottle, but a significant concern when holding the bull horns. A better cage (not plastic...), such as a Gorilla would have prevented this issue. Other than that, $40 for a little plastic contraption is a bit over-priced.
Fits a P5, forward facing bottle, holds Garmin close to where it should be.
Cage doesn't hold the bottle very well. Plastic construction Price

Great idea, poor execution.

I really liked the concept for clean cockpit and multi-purpose BTA water bottle/computer mount. However, the computer holder only goes in one direction back towards the rider. It puts the computer line of sight down and back instead of forward so not much farther forward than a stem mount. I feel they could have engineered the clip in to go in from either direction for better functionality and adjustability. I modified it myself to work better but I could have done the same mod to a basic cage.

I bought this BTA cage because I liked the way they integrated the computer mount to the cage. The only thing I would suggest is to make other manufactures (besides garmin) computer mounts since it is detachable. All in all a great product!

Great placement, holds bottle well...

It's puts the Garmin in a perfect place to see and monitor your progress. Bottle is easy to get in and out of holder. Would like to see a more stable 'securing mechanism'. The zip ties work OK. Something that I could use to take it on and off repeatedly (like the velcro straps used on other systems).
