COROS DURA Solar GPS Bike Computer – 120-Hour Battery, Dual-Frequency GPS & Navigation

The COROS DURA Solar is COROS's flagship GPS bike computer — a full-featured cycling head unit with a 120-hour battery life extended by solar charging, dual-frequency GPS, built-in global offline maps, real-time Google Maps rerouting, and a comprehensive safety and connectivity suite. It's the dedicated on-bike companion for cyclists who want serious navigation, sensor integration, and long-ride capability in a single device — complementing rather than replacing a COROS watch for athletes who train across multiple disciplines.

The 2.7-inch MIP colour touchscreen with adaptive backlight delivers clear visibility in all lighting conditions, with a combined digital dial and single-button interface for intuitive one-finger operation while riding. Dual-frequency GPS (L1+L5) intelligently switches modes based on satellite strength to optimise both accuracy and battery life, delivering reliable tracking in urban canyons, dense tree cover, and complex terrain. Real-time smart rerouting powered by Google Maps keeps you on course when you miss a turn, while built-in global offline maps provide turn-by-turn navigation across mountain trails and city streets without cellular coverage. Solar charging adds approximately 2 extra hours of ride time per hour of sunlight, making the DURA genuinely capable of multi-day bikepacking and ultra-distance events.

Connectivity covers Bluetooth and ANT+, supporting power meters, heart rate monitors, speed and cadence sensors (including the COROS Bike Speed Sensor and Cadence Sensor), and electronic drivetrains from Shimano Di2 and SRAM eTap. Safety features include crash detection with emergency contact alerts, Group Tracking for monitoring your riding group, and a loud Bike Alarm for theft deterrence. Post-ride data syncs in seconds to the COROS app and Strava. Phone notifications (calls and texts) display directly on the device. Browse the full Coros range or our computers and GPS collection.

What It's Good For

• Long-distance and ultra-endurance cycling — 120-hour battery with solar charging for multi-day rides
• Dual-frequency GPS (L1+L5) — accurate tracking in urban, wooded, and complex terrain
• Real-time Google Maps rerouting and built-in global offline maps for turn-by-turn navigation
• Bluetooth and ANT+ — connects to power meters, HRMs, speed/cadence sensors, Di2 and eTap
• 2.7-inch MIP colour touchscreen with digital dial and single-button interface
• Crash detection with emergency contact alerts, Group Tracking, and Bike Alarm
• Lightning-fast post-ride sync to COROS app and Strava
• Phone notifications (calls and texts) displayed on device

What It's NOT Good For

• Runners or multisport athletes who primarily need a wrist-worn device — a COROS watch is the better choice for running and multisport
• Casual cyclists who don't need navigation, sensor integration, or safety features
• Users wanting a simpler, lower-cost head unit without advanced GPS or mapping
• Indoor-only training — a dedicated smart trainer and training app is more appropriate for turbo use

Frequently Asked Questions

How does solar charging work and how much does it extend battery life?
The DURA's solar panel supplements the internal battery during outdoor use. In good sunlight conditions, solar charging adds approximately 2 extra hours of ride time per hour of riding. This means on a long sunny day, the effective battery life can extend well beyond the base 120 hours. Solar charging is most effective in direct sunlight and less effective in overcast conditions.

Is it compatible with my power meter and electronic groupset?
Yes — the COROS DURA supports both Bluetooth and ANT+ connectivity, making it compatible with the vast majority of power meters, heart rate monitors, and speed/cadence sensors on the market. It also supports electronic drivetrains including Shimano Di2 and SRAM eTap, allowing you to view gear information and shifting data on the device.

Can I use it without cellular coverage?
Yes — the DURA has built-in global offline maps and turn-by-turn navigation that work without cellular signal. Real-time Google Maps rerouting requires a phone connection, but the offline maps provide full navigation capability in remote areas without any connectivity.

How does it work alongside a COROS watch?
Many athletes use the DURA as their primary on-bike head unit for detailed cycling data and navigation, while wearing a COROS watch for multisport tracking, running, and health monitoring. The two devices work independently and both sync to the COROS app, giving you a complete picture of your training across all disciplines.
