Between the Arm (BTA) setups have now become pretty standard. We have gone from simple zip-tied cages to increasingly sophisticated setups, including computer mounts, straws, and fairings. But not everyone is looking for sophisticated or complex. Sometimes all we want is an efficient way to store a standard 20oz bottle on your bars—having a computer there may be an added bonus. If this sounds familiar, Zipp built the new Vuka Alumina BTA Mount just for you.
The Vuka Alumina BTA Mount
In many ways, the Vuka Alumina seems like the evolution of the original Profile Design HC Mount. Like the HC, the Vuka’s main design element is a bridge between the two aerobars. However, where the HC mount was secured via zip ties, the Vuka uses pair of securable clamps. Mounted to the bridge is a combination bottle boss and quarter turn mount for Garmin Edge computers (unfortunately the 910xt quick release kit will not work).
The mount alone weighed in at 106g (with hardware).
Vuka BTA Carbon Cage
We mounted a Vuka BTA Carbon Cage to our Vuka mount. Weighing in at 24g, it’s an extremely light-weight cage. So far we’ve experienced no bottle launches. In fact, we would say the cage is actually a little on the tight side. You have to be pretty deliberate about grabbing a bottle—it won’t just slide out. Zipp calls this “super secure bottle fitment.” We call it “snug.”
This is easily one of our favorite cage-only BTA solutions – if only for the perfect location of the computer mount. The computer is placed where you can easily read it, even in the aero position. When talking to Zipp, a completely usable computer position is one of the key design elements they had to have, and they absolutely succeeded.
The mount itself is strong and secure. We originally had some concerns that a single bridge may cause the bottle to vibrate or bounce. However, the mount itself is wide enough to get a solid connection to your bars, and the bottle never moved.
The only real issue we had with the system is the cost. At $140 for the mount and cage combined ($65 mount\$75 cage) this is far from a cheap solution. There are quite a few options that offer similar functionality for less. However, perfection never comes cheap. And having the computer exactly where you want is going to be worth every penny to quite a few. That really sums up the Vuka BTA system – for a price, it provides one of the simplest and well-executed options out there for a bottle-only setup. Speed Weaponry at its finest.
