Expert opinion
Dura 2 Solar is a high-quality, lightweight cycling computer. Its strengths are exceptional battery life, solar charging that works, a large and responsive display, broad sensor compatibility and comprehensive training features. Early reviews point to good GPS accuracy, and the mapping is clear and fluid.
It falls short of being a complete all-rounder. Rerouting is calculated on a paired smartphone rather than on the unit, the six ride profiles are fixed, and some software features are still immature. At £429 / $499 / €499 without a mount, or £479 / $549 / €549 with one, it is also far less compelling on value than the original Dura.
Dura 2 Solar is an excellent option for endurance cyclists and existing COROS users who put battery life and training first. Its price and navigation limits make it hard to recommend unreservedly over established rivals such as Garmin.
The original Dura looked ugly and unusual; Dura 2 Solar just looks unusual. Dropping the dial makes it less easy to use, though it brings Dura in line with its rivals. The on-screen menus look poor but are generally easy to use. Where usability suffers, it is in how the computer links to the COROS app.
On the hardware side, the screen grows from 2.7 to 3.5 inches and runs edge to edge, the solar panel moves below it and doubles as two pressure-sensitive buttons, and a microphone adds voice control for starting rides, rerouting and media. Street and trail names now appear on the map, climb alerts work without a loaded route, and a bike bell, action-camera control and Campagnolo support join Shimano and SRAM. Battery life is unchanged at 120 hours, and the unit-only price includes no mount at all.

Battery life is identical to Dura. COROS’s own example is a three-hour July ride in Boulder averaging 75,000 lux that returns six hours of charge. Autumn and winter sun in northern Europe delivers far less, and a panel below the screen sits closer to the rider’s shadow than Dura’s did. For comparison, Edge 1060 is rated at 20 hours of demanding use and 60 hours in battery saver.
