After plenty of speculation on internet forums, the second iteration of the COROS DURA has arrived in a completely redesigned package with some important new features.
The DURA 2 Solar touts the "world's longest battery life" of any GPS cycling computer, and it pairs that headline claim with a 3.5-inch display, aero profile, solar charging, and a lighter premium build.
With that said, COROS has doubled the price of its initial offering, putting itself in direct competition with premium brands that have dominated the cycling-computer space for years.
We got our hands on a unit. Here are our thoughts.
The COROS DURA 2 Solar GPS cycling computer is available beginning November 3, 2026, through the official COROS store.
Quick Tip
How Easy Is the COROS DURA 2 Solar to Set Up?
The DURA 2 Solar is delivered in simple packaging that includes a lanyard and braided USB-C cable. A wall adapter and handlebar mount are notably absent. COROS sells the unit without a mount and also offers mount bundles and separate mounting options.
Getting started was straightforward and intuitive. We experienced no issues setting up our profile, updating the software, connecting to third-party apps such as Strava, or pairing sensors. The entire process took less than five minutes.
The data pages are editable through the COROS app and can then be pushed to the device. They can also be edited directly on the computer itself.
What Is the DURA 2 Solar Hardware Like?
This is where the DURA 2 Solar really shines.
At 99 grams, it's remarkably light for a large-screen cycling computer. Despite the low weight, it doesn't feel cheap. The woven carbon-fiber backplate and tapered aluminum-alloy bezel contribute to the premium feel, and the overall form factor is sleek, aerodynamic, and significantly slimmer than its predecessor.
The upper profile measures just 5.7 millimeters thick, according to COROS. The device also incorporates haptic controls, touchscreen input, and voice features alongside its physical controls.
COROS has clearly invested in making the DURA 2 Solar feel more cohesive as a piece of hardware. The clicks, vibrations, sounds, and swipes all contribute to that impression.
With its thin profile, responsive touchscreen, and industry-leading battery performance, the hardware is the clear winner.
How Good Is the 3.5-Inch Display?
The screen has grown 30 percent over the previous version to a 3.5-inch Memory-in-Pixel touchscreen display. COROS also says pixel density increased by 17 percent compared with the original DURA.
The touchscreen was accurate and responsive during testing and supported gestures such as pinching to zoom into maps. In direct sunlight, the display was vivid and bright enough to read easily. In the shade, however, we sometimes found it harder to read. It wasn't a deal breaker, but it was noticeable.
COROS says the touchscreen is designed to remain responsive with gloves and in wet conditions. Full current specifications are available on the official COROS DURA 2 Solar product page.
How Long Does the COROS DURA 2 Solar Battery Last?
Now for the main event: battery life.
The lower section of the unit contains a built-in solar panel that also incorporates the two haptic controls. COROS rates the DURA 2 Solar for 120 hours of GPS battery life from a single charge before accounting for solar input.
COROS also claims that, under its specified direct-sun conditions, the monocrystalline solar panel can add up to two hours of ride time for every hour of direct sun.
We didn't test the battery to its full limit, but we were impressed with its endurance. In practice, actual results will depend on factors such as GPS mode, connected features, and the amount of usable sunlight the solar panel receives. During our testing, battery life was not something we had to worry about across multiple long days in the saddle.
Quick Tip
How Well Does the DURA 2 Solar Handle GPS and Sensors?
The DURA 2 Solar supports Bluetooth and ANT+ sensor connectivity, including support for tire-pressure sensors. In our testing, we paired six sensors simultaneously and had no issues with dropped connections.
GPS tracking was also excellent during our rides and closely matched the readings from a competitor's bike computer. The device acquired GPS within a few seconds for our workouts, and we did not experience signal loss.
The connection between the COROS app and the DURA 2 Solar was equally consistent. Maps moved between devices quickly, completed workouts uploaded promptly, and rides were pushed to third-party apps such as Strava without trouble.
For riders already using COROS watches, ACTIVE has also reviewed the COROS PACE 4 Pro, another recent device built around the company's training ecosystem.
How Good Is the Mapping and Navigation?
The previous DURA's mapping attracted criticism for inconsistent performance and accuracy. Based on our time with the DURA 2 Solar, COROS has made meaningful improvements.
It's easy to create routes in the app or select saved Strava routes and push them to the device. Routes load quickly, streets are well defined, and street names are included. Once rolling, the unit warned us roughly 300 feet before a turn when we were following a planned route.
When we missed a turn, rerouting generally did a decent job of guiding us back to the planned course. In our testing, the process required the paired phone connection, which is consistent with COROS's navigation architecture. Reroutes loaded quickly and worked more dependably in developed areas.
COROS also offers offline rerouting when map regions have been downloaded to the paired phone ahead of time. That feature is designed to provide rerouting where cellular service isn't available while still using the phone as part of the routing process.
Overall, mapping worked well, but it wasn't flawless. We noticed some inconsistencies detecting climbs, and rerouting occasionally restarted repeatedly without finding a suitable solution.
COROS continues to expand navigation across its ecosystem. ACTIVE has previously covered the company's AllTrails integration for outdoor navigation.
What Other Features Stand Out?
There are several smaller touches worth mentioning.
- Virtual bike bell: Double-tap the screen to trigger a digital bell.
- Bluetooth media controls: Control compatible phone audio during the ride.
- Voice and audio: The unit includes a microphone and speaker for supported controls and audible navigation prompts when connected as required.
- Training metrics: COROS provides cycling-fitness and workout analysis through the device, COROS app, and Training Hub.
- Mapping controls: Swipe, pinch, and pan through global maps on the touchscreen.
These don't necessarily define the device individually, but together they make the DURA 2 Solar feel more complete than its predecessor.
Is the Optional Mount Worth Buying?
COROS sells the DURA 2 Solar for $499 without a mount and lists a $549 option that includes a mount. We tested COROS's aluminum quarter-turn out-front mount and found it well designed, cleanly machined, and secure.
It's a premium-feeling accessory that matches the head unit nicely. Our criticism is straightforward: At this price, we'd prefer to see a mount included.
That omission is particularly notable because the new DURA 2 Solar is no longer positioned as the aggressive-value alternative its predecessor was. The price now places it directly against established premium cycling computers.
Is the COROS DURA 2 Solar Worth $499?
Overall, the DURA 2 Solar is a refreshing option in the GPS cycling-computer space. It's clear COROS listened to feedback from its first-generation device, and the second version feels much more cohesive and thoughtful.
With its thin profile, responsive touchscreen, lightweight carbon-and-alloy construction, and exceptional claimed battery performance, the hardware is the clear winner. Software-wise, the interface is clean and easy to navigate, though mapping and rerouting still showed occasional inconsistencies during our testing.
The larger question is value.
COROS built a loyal following by offering capable products with strong battery performance at prices that often undercut competitors. At $499 without a mount, the DURA 2 Solar competes much more directly with established premium ecosystems.
That raises the bar. The hardware is already compelling. As COROS continues refining the software, the DURA 2 Solar could become more competitive for cyclists beyond the company's existing user base.
