Coros Launches Dura 2 Solar Bike Computer at $499
Coros has released its second-generation bike computer, the Dura 2 Solar, shifting its market position from a budget-friendly alternative to a higher-end competitor priced at $499 for the unit alone, as Velo reported. The device brings a major hardware redesign, featuring a 3.5-inch Sharp Gen 3 memory-in-pixel touchscreen with a 336×620 resolution, a T700 carbon fiber backplate, and an anodized aluminum bezel that tapers to 5.7mm at the top edge, according to reporting by Slowtwitch.
Dura 2 Solar Offers 120 Hours of GPS Runtime
The Dura 2 Solar retains the headline battery performance of its predecessor, offering 120 hours of runtime in all-systems GPS mode and 70 hours in dual-frequency (L1+L5) mode before factoring in solar charging. Coros claims the integrated solar panel adds up to two hours of battery life for every hour spent in direct sunlight. Charging from empty takes approximately 2.5 hours using a USB-C cable at normal temperatures.
Offline Re-Routing Removes Need for Cellular Data Signal
Updates include free global Mapbox maps featuring street and trail names, points of interest, and surface types, which users download by region through the Coros smartphone app. Unlike the original 2024 model, which relied on a live cell signal for cloud-based re-routing, the Dura 2 Solar introduces offline re-routing. This function calculates new routes through the companion app via Bluetooth as long as the map region has been downloaded in advance, eliminating the need for an active cellular data signal in remote areas.
Hardware Controls and the Omission of the Digital Dial
The device also introduces voice control capabilities for starting and ending rides, setting alerts, dropping points of interest, and managing media playback. The touchscreen is designed to distinguish between water droplets and fingertips to prevent false inputs during wet-weather rides.
EvoLab Ecosystem Tracks Metrics Without a Subscription
The unit runs on the EvoLab training ecosystem, tracking metrics such as training load, recovery time, VO2 max estimates, and FTP test results without requiring a subscription. Connectivity options include ANT+, Bluetooth, and Wi-Fi for direct workout syncing. The computer is sold as a standalone unit for $499, or for $549 when bundled with the brand’s new anodized aluminum standard mount, while individual mounts cost $79.
