Sigma ROX 12.0 Sport

Sigma might have just created the ultimate bike computer with the Sigma ROX 12.0 Sport. If you have read any of the reviews, you know this computer brings the goods. For starters, the ROX 12.0 Sport is literally loaded with training features. You can customize up to 6 training pages selecting from 30 different training views, have accesses to various sport profiles and can even create custom workouts.

The mapping and navigation features are equally as impressive. Using the OSM database, the ROX 12.0 Sigma bike computer features customized routing and unique map views. In addition, you get a very easy to use, touchscreen interface that makes navigating the ROX 12.0 menus easy and intuitive. All of this is packed into a durable case with a clear, transflective display made of Gorilla glass. This casing makes sure your Sigma ROX 12.0 Sport works and stays looking great in all weather conditions.



  • Professional Training System – Personally customize up to 6 training pages selecting from 30 different training views.

    The Sigma works really well. It’s clear, easy to read, gives outstanding turn-by-turn directions. The battery life, however, isn’t as long as advertised, at least with the backlighting on.
