COROS Dura 2 Solar Review: Huge Battery, $549 Price, Buggy Launch
BiohackingThe COROS Dura 2 Solar costs $549 with a mount, more than double the $249 of the Dura it replaces. DC Rainmaker’s in-depth review says the extra money buys a sleek new design and battery life that is still excellent, but not the working navigation that rivals from Garmin, Wahoo and Hammerhead deliver at $499. For riders who picked COROS for cheap, long-lasting head units, the Dura 2 is a different kind of product.
Why This Comparison Matters
The first Dura won fans by undercutting the competition and lasting far longer between charges. DC Rainmaker’s review argues COROS is now aiming at the premium players in their own price band. That puts the Dura 2 up against units like Garmin’s Edge line, which Stack Archive looked at in its Edge 1060 vs Edge 1050 comparison. The Dura 2 goes on sale November 3, 2026, and costs $499 without any mount. COROS’s Dura page currently lists the Dura 2 Solar as available soon.
What Makes It Different
The Dura 2 is new inside and out. COROS dropped the rotating crown, moved the solar panel to the bottom of the unit, and added a speaker, microphone, bike bell, voice prompts and voice control. The screen grows from 2.7 to 3.5 inches, with a refresh rate COROS claims is the fastest of any MIP display.
Battery life is the standout, though DC Rainmaker’s results varied widely with the sun:
| Ride conditions, with navigation | Battery used | Estimated battery life |
|---|---|---|
| Sunny, earlier firmware | About 4% in 5 hours | 123 hours |
| Sunny, latest firmware | 1.6% in about 50 minutes | 47 hours |
| Overcast early evening | 1.3% in 60 minutes | 80 hours |
| Rainy, no solar gain | 5% in 62 minutes | 22 hours |
The reviewer thinks it falls short of COROS’s claim of 120 hours without solar, but still calls the battery life incredible on most days. GPS and elevation tracks nearly always matched Garmin’s Edge units.
The Catch / Who It’s For
The trade-off for that battery is the screen. It’s fine in sun or cloud but much dimmer than rivals in shade, and in heavy rain the touchscreen became mostly useless. Some menus can only be reached by swiping it.
The software is the bigger problem. The review lists voice control that couldn’t understand commands above about 15 km/h, constant ANT+ dropouts, climb pages without distance or ascent remaining, and rerouting that “rarely works properly.” Rerouting also needs a connected phone. COROS shipped a firmware update the night before the review, but the issues were still there on retest. COROS says that’s the firmware buyers will get at launch, and it has promised further updates, including multiple bike profiles and support for up to 32 sensors. There are no mounts in the box.
The So What
Cyclists who need multi-day battery life above all, such as ultra-distance and bikepacking riders who navigate a fixed route, are the closest fit, and should wait for post-launch firmware before paying $549. DC Rainmaker’s verdict is that Garmin, Wahoo and Hammerhead deliver far more at $499, so riders who rely on rerouting, ride in heavy rain or want voice control should compare those units first.
