COROS has launched Dura 2 Solar, a redesigned solar bike computer with a 3.5-inch edge-to-edge touchscreen, voice control and the same 120 hours of GPS riding as the original Dura. It costs £429 / $499 without a mount, or £479 / $549 with one, and goes on sale on 3 November 2026. A nice touch to cut down on the waste that often comes with a new device.
- The screen grows notably from 2.7 to 3.5 inches and now fills the upper part of the unusually designed unit.
- The solar panel moves below the screen and doubles as two pressure-sensitive buttons.
- The knob is gone, replaced by buttons on each side, a touchscreen, and voice.
- Maps gain street and trail names, and climb alerts work without a loaded route.
- The price with a mount has more than doubled, from $249 to $549.
What Dura 2 Solar lets a rider do
Voice control is the biggest change for riders who keep both hands on the bars. A ‘windproof’ microphone starts and ends rides, reroutes, drops points of interest, sets alerts and controls media, and the speaker reads turn alerts aloud.
The map details are enhanced with street and trail names, points of interest, pan and pinch-zoom- all smoother thanks to more powerful internals (a faster Ambiq Apollo 510 processor). Climb alerts appear on any ride, with or without a route. The COROS app on a paired phone remains essential for rerouting, and it now works without mobile data when the map region is downloaded. Without the phone, Dura 2 Solar reroutes by drawing a line back to the nearest point on the route.
Smaller touches round out the list: a double-tap bike bell, action-camera control for selected GoPro, DJI, and Insta360 models, Campagnolo shifting alongside Shimano and SRAM, and the option to load a workout or a new route mid-ride without stopping the recording. It connects up to 15 sensors over Bluetooth 5.4 and ANT+.
Battery life and solar
COROS rates Dura 2 Solar at 120 hours in All Systems GPS and 70 hours in dual-frequency before solar, unchanged from Dura. The monocrystalline panel adds up to two hours of riding per hour of direct sun at 75,000 lux, the figure COROS gives for a clear summer morning in Boulder. A northern European winter will deliver a fraction of that, and the panel now sits behind the screen, closer to the rider’s shadow, which may cause minor recharging issues.
The full figures are on the COROS Dura 2 Solar specifications page.
Design and mounts
Design is the focus of this generation. “For too long, bike computers have looked like functional tools attached to otherwise beautiful bikes,” said COROS CEO Lewis Wu. “We wanted to build a bike computer that cyclists are proud to put on their bikes.”
The unit weighs 99g and pairs a woven carbon fibre backplate with a 5.7mm-thin aluminium bezel at the upper edge. It is IP67 rated and fits existing quarter-turn mounts. The cheapest version comes with no mount, so riders without a quarter-turn mount need the £479 bundle or a separate £69 / $79 aluminium mount. The Out-Front version tilts from -7 to +5 degrees for integrated cockpits.

Dura 2 Solar goes on sale at 6 am Pacific time (2 pm GMT) on Tuesday 3 November 2026 from the COROS website. COROS’s Dura page has said since the summer that Dura is sold out and will not be restocked, and the October leak showed the new design early.
First take
The original Dura looked ugly and unusual; Dura 2 Solar just looks unusual. The battery life, solar charging, large display and training features are strong, but it’s a disappointment they haven’t been improved. If Garmin makes an Edge 1060 Solar for 2027, I reckon it will beat Coros on the enduro battery front. Rerouting still depends on the phone, the ride profiles are fixed, and the price has moved a long way from the original. Dropping the dial makes it marginally less easy to use, though it brings Dura in line with touchscreen and button control of rivals.
It feels a tad overpriced, but if you need the excellent battery life and solar, you will still consider this. Or buy a battery pack.
How it compares
Dura 2 Solar arrives two days after Garmin Edge 1060, which shares the 3.5-inch screen size and voice control. The Edge 1060 costs £699.99 / $799.99, routes on the device, and lasts 20 hours of demanding use, while the Dura 2 Solar costs £270 less and lasts 120 hours in its longest mode.
