COROS Launches the Dura 2 Cycling Computer: A Premium Price Point, Expanded Features, and Familiar Launch Pains

COROS has officially announced the launch of its latest cycling computer, the COROS Dura 2, introducing a complete redesign, a suite of new hardware and software features, and a significant pricing shift. The new unit more than doubles the price of its predecessor, the now-discontinued Dura 1, moving from an introductory $249 up to $549 with a mount, or $499 without any mounting hardware included in the box.

Despite the steep price increase, the Dura 2 maintains the brand’s industry-leading battery life claims while adopting a striking external redesign. However, real-world testing reveals a product that shares both the impressive capabilities and the software instability characteristic of its predecessor’s turbulent market entry.

What’s New in the COROS Dura 2

At first glance, the COROS Dura 2 bears little resemblance to the original model. Most notably, COROS has ditched the rotating Digital Crown in favor of a sleek, modernized chassis that several observers have likened to the styling of a Motorola flip phone. The solar panel has been shifted from the top of the unit to the bottom, creating a more traditional "chin" look reminiscent of other modern bike computers.

Alongside the visual overhaul, COROS has packed the unit with a substantial list of new hardware and software integrations. The device now features two pressure-sensitive touch areas positioned directly above the lower solar panel, acting as up-and-down menu controls that function reliably even when wet or operated with gloves. A new left-side button joins the existing right-side start/stop/select button, while the physical build now includes a full speaker, microphone, and a dedicated bike bell feature.

The inclusion of a microphone and speaker enables voice control capabilities via a long-hold of the lower-left button, alongside turn-by-turn voice prompts for navigation. Other software additions include the ability to save voice pins, cancel manual laps mid-ride, display a power curve chart, support tire pressure sensors, and control phone media directly from the device screen. The user interface has also received a slight refresh, paired with a revamped customization suite inside the COROS mobile application.

On the hardware side, the screen size has increased to 3.5 inches, boasting a refresh rate of 38 Hz—which COROS claims is the fastest of any Memory-in-Pixel (MIP) display on the market. The device is also capable of offline re-routing, though it still requires a connected smartphone to function.

COROS has also adopted the modern tech industry trend of staging feature rollouts, promising several additional capabilities via firmware updates later this year. These forthcoming additions include multiple bike profile support, expanded compatibility for up to 32 sensors, a cycling-specific heart rate recovery metric for interval workouts and post-activity analysis, and Campagnolo electronic drivetrain support by the end of 2026.

In the Box and Mounting Controversy

One of the most contentious aspects of the Dura 2 release is the contents of its packaging. Beyond the unit itself, a lanyard, and a braided USB-C cable, the box is remarkably sparse. Most notably, COROS has chosen to include zero mounting hardware of any kind—not even simple rubber band handlebar mounts that cost pennies to manufacture.

For a $500-plus bike computer, the absence of basic mounting options has drawn criticism, forcing users to source quarter-turn mounts separately from third-party manufacturers or brands like Garmin. The rear of the Dura 2 features the standard Garmin quarter-turn mounting interface, which is physically removable in the event of breakage, but the lack of an out-of-the-box mounting solution represents a noticeable departure from industry norms.

The Basics: Display, Controls, and Audio Features

Once mounted, the Dura 2 presents a striking form factor. The pressure-sensitive buttons at the base of the unit provide tactile feedback that functions seamlessly in heavy rain and while wearing thick cycling gloves. However, accessing deeper system settings—such as display brightness, volume, and satellite configurations—requires swiping down from the top of the touchscreen. While responsive in dry weather, this touchscreen interface becomes largely unusable when heavy rain pools on the glass, posing a challenge given the lack of button-based menu alternatives.

Display visibility presents a classic trade-off. In bright, direct sunlight, the MIP display is exceptionally clear and easy to read. However, in shaded environments, such as riding beneath tree cover or under the shadow of the rider’s own body, the screen appears significantly dimmer than competing devices from Wahoo and Garmin. While still legible, this reduced brightness is the deliberate mechanical compromise that allows the Dura 2 to achieve its phenomenal battery longevity without constantly firing power-hungry backlights.

Sensor pairing covers a comprehensive array of protocols, supporting ANT+ and Bluetooth heart rate monitors, power meters, radar systems, lights, eBikes, and electronic drivetrains from SRAM and Shimano, alongside Bluetooth FTMS smart trainers. However, any existing COROS wearables linked to a user’s account automatically count toward the device’s current sensor limit and cannot be disabled, an annoyance that is expected to be addressed when sensor limits are expanded to 32 in a future update.

The electronic bike bell feature allows users to double-tap the screen to sound a digital horn. While the tone is pleasant, the speaker volume and lower pitch struggle to project effectively in traffic compared to established competitors. Furthermore, unlike rival ecosystems, the Dura 2 currently lacks integration with SRAM or Shimano auxiliary hood buttons, preventing riders from triggering the digital bell without taking their hands off the handlebars.

Voice control has also been introduced, though real-world testing proves it largely ineffective outside of controlled, stationary environments. Even moderate wind speeds or riding at velocities above 15 kilometers per hour quickly overwhelm the microphone, rendering voice commands unreliable unless the rider comes to a near-stop. Furthermore, the limited command dictionary currently restricts utility for critical ride data like remaining distance or ascent.

Navigation and Re-Routing Performance

Navigation capabilities allow users to sync routes via third-party platforms like Strava into the COROS app, though routes must still be manually pushed to the device rather than populating automatically. Turn-by-turn prompts arrive reliably roughly 100 meters prior to a junction, an improvement over the erratic directional guidance of the original Dura.

Climb detection notifies riders upon approaching an incline, though the dedicated climb page exhibits peculiar behavior by displaying the distance to the start of the climb increasing as the rider ascends. Re-routing capabilities also show mixed results. While minor missed turns on simple grid layouts occasionally trigger functional recalculations, other instances result in erratic pathing suggestions—such as directing cyclists toward steep, technical hiking trails—or failure to re-route entirely, trapping the device in a repetitive calculation loop.

Solar Performance and Battery Life

The defining feature of the Dura series remains its battery performance, bolstered by solar charging capabilities. Under bright Mediterranean sunlight, testing indicates solar gains of approximately 0.5 percent per hour when left stationary, translating into meaningful supplementary energy given the device’s low baseline power consumption.

Real-world battery drain varies depending on environmental conditions and route navigation. On fully sunny days with navigation active, battery drain is minimal, yielding exceptionally high projected runtime estimates. Conversely, on overcast or rainy days where solar gains are entirely absent, the battery depletes noticeably faster, aligning more closely with traditional bike computers while still offering robust endurance.

GPS and Elevation Accuracy

Location tracking and barometric altimetry represent a strong point for the Dura 2. Field testing across complex mountain terrain and winding switchbacks demonstrates high spatial accuracy, with GPS tracks matching or exceeding the performance of reference units. Elevation tracking mirrors Garmin and barometric altimeters closely, displaying only a minor initial offset during the first ten minutes of a ride before stabilizing for the remainder of the session.

Ongoing Software Stability Issues

Despite firmware updates issued immediately prior to its commercial release, testing highlights a series of persistent software bugs. Users transitioning to the final retail firmware may encounter challenges including occasional ANT+ sensor dropouts when simultaneously paired with Bluetooth devices, non-functional Strava Live Segments, and recurring navigation re-routing failures. While COROS has a history of resolving software instability over extended product lifecycles, the initial launch state reflects many of the growing pains familiar to users of the original Dura.

Wrap-Up

COROS has cultivated a dedicated following by offering hardware focused on extreme battery life and competitive pricing. With the Dura 2, the company is attempting to pivot directly into the premium cycling computer market, challenging established industry giants at a price point of $549.

While the device boasts a sleek physical design, exceptional solar-assisted battery longevity, and reliable GPS tracking, its current software limitations, inconsistent navigation re-routing, and lack of bundled mounting hardware make it a challenging proposition at the top end of the market.
