Test: With the Pro Scio Alti Ant+, the Dutch accessory manufacturer Pro Components has a real functional wonder in its range. This is primarily due to the Ant+ compatibility, which offers almost endless possibilities. The inconspicuous bike computer also does well in the other disciplines.
As already mentioned, the Pro Scio Alti Ant+ is a real powerhouse when it comes to the range of functions. Although only a speed sensor is included in the scope of delivery, all kinds of sensors can be connected thanks to the full Ant+ compatibility. Heart rate, cadence and power meter - all no problem thanks to the modern radio standard. It is also nice that the sensors are not manufacturer-bound. For example, the computer can easily be operated with an existing chest strap for heart rate measurement - provided this also works in the Ant+ standard. As an additional treat, the Scio can also communicate with Di2 circuits from Shimano. After they have been equipped with the appropriate wireless kit, the current gear can be read on the display at any time. You will also receive a warning if the charge level of the Di2 battery drops below 25%. In addition to the large number of sensors, the version we tested with the addition "Alti" also offers an integrated altitude measurement.
Installation
Attaching the computer and speed sensor is extremely easy thanks to wireless installation. The handlebar mount is minimalistic but well thought out - it is attached to the handlebars or stem using rubber rings, the computer pushed on, done. The start-up of the Scio also runs smoothly, although not necessarily intuitively. The good instructions lead the user safely through the setup process. Pairing with the desired sensors also works straight away. After 5 minutes we are ready to go.
Practice
The Scio is operated using two sufficiently large rubber-coated buttons under the display. The first thing we noticed during the test was the different pressure point - one of the two buttons was much harder to press than the other. This circumstance took some getting used to, especially at the beginning, and led to one or the other depressor. The menu navigation is intuitive, despite the many functions and sensors - Pro has solved that really nicely. After all, it's rare to be able to operate a modern bike computer without studying the instructions in detail, but with the Scio it's actually not a problem.
The display is sufficiently large and very easy to read, thanks to the switchable backlight, even in the dark. The layout on the display is very clear, but a maximum of two functions (three for Di2) can be displayed at the same time. The display looks tidy, but those who like to see as many values as possible at once may not be happy with the Scio. The radio connection to the sensors was stable at all times and we had no faults to complain about.

Klaus Beck says
I can no longer connect my Di2 to my Scio Alti+. It went well for almost 2 years, suddenly it didn't work anymore. I've done everything I can. Battery charged, unplugged, gears shifted, everything. He no longer mates. What's going on there. Who can help?
