Expert opinion
Dura was a brilliant idea executed poorly, with slightly sub-standard components and shabby software, all sold too quickly. Its only standout was battery life: 120 hours of GPS riding, with solar charging that in strong sun could keep it running indefinitely. Everything else could be had for less from Lezyne, Bryton or Magene plus a cheap battery pack, and older Garmin and Wahoo models did a better job at similar sale prices.
At launch it dropped power data, recorded sticky cadence and mistimed some data, which corrupted the power curve. The touchscreen was slow to respond and struggled in the wet, the dial was too easy to knock mid-ride, the map was small and hard to read, routes were slow to load, climb information only worked on a loaded route, and rerouting needed a phone with signal. It was an odd-looking thing, too. My verdict in the COROS Dura review was simple: don’t buy it.
COROS did keep working on it through 2025 and 2026. Street names on turn alerts, three rerouting modes, voice alerts, a topographic map layer, 100 stored routes, ten data pages, Strava Live Segments and configurable Di2 buttons all arrived by firmware. The hardware weaknesses never changed: the touchscreen, the dial, the screen size and the looks. Its successor, Dura 2 Solar, keeps the battery, drops the dial and grows the screen to 3.5 inches.

In my own testing on the October 2024 firmware, maximum backlight and dual-frequency GPS gave about 40 hours, and a lower backlight with All Systems GPS made 60 to 80 hours realistic. Autumn sun in south-west London added about 1% over 15 hours of riding.
