More information about the product

Exceptional battery life with solar charging

The DURA 2 SOLAR was developed specifically for long rides and multi-day adventures. Even without solar charging, the cycling computer achieves a runtime of up to 120 hours. When exposed to direct sunlight, the integrated solar panel can generate additional energy and further extend the runtime while riding.

Large touchscreen with a size suitable for optimal visibility

The bezel-less 3.5-inch display offers high-detail visuals and responds reliably to input from bare hands, gloves, or in wet conditions. Maps, training data, and navigation instructions remain easy to read at all times.

Modern navigation for every adventure

In addition to global maps, the cycling computer supports turn-by-turn navigation, route planning, waypoints, return-to-start, and automatic route recalculation. Maps can be conveniently managed and synced via the COROS app.

Flexible Control via Touch, Buttons, and Voice

The DURA 2 SOLAR combines a touchscreen, haptic buttons, and voice control. Starting rides, accessing navigation, or adjusting settings is quick and easy—even while riding.

Comprehensive training features

With EvoLab training analyses, structured workouts, FTP tests, training load metrics, recovery analyses, and customizable data screens, the cycling computer supports both beginners and performance-oriented athletes in targeted training management.
