Coros has announced the Dura 2 Solar, a $499 bike computer with a 3.5-inch touchscreen, voice controls and an integrated MCP gateway for sending ride data to Claude and ChatGPT. The company lists battery life of up to 120 hours without solar charging and says sunlight can add two hours of use per hour of exposure. Sales are scheduled to begin November 3, 2026.
Coros has announced the Dura 2 Solar, a $499 bike computer that adds voice control and an integrated MCP gateway while retaining the brand’s solar-assisted battery features. The company says the device will go on sale November 3, 2026; the announcement positions it as an update to the Dura Solar, with a larger screen and a lower listed weight.
The Dura 2 Solar has a 3.5-inch SHARP MIP touchscreen with a resolution of 336 by 620 pixels. That is larger than the 2.7-inch display on the original Dura Solar. Coros says the touchscreen is designed to remain responsive with wet or gloved fingers. The display’s stated refresh rate is 38Hz, which the company’s product information describes as the fastest for an MIP display.
Coros lists the new unit at 99 grams, compared with 102 grams for its predecessor, and says it uses a carbon backplate. The company rates battery life at 120 hours without solar charging and says each hour of sunlight exposure can add two hours of battery life. That solar figure is a manufacturer claim, not a separate test result supplied with the announcement.
Voice commands can be used to change data pages, set reminders and create ride alerts, according to the product description. Riders can also dictate post-ride training notes for upload to the Coros app and speak map pins or points of interest into their saved riding maps. The device also adds haptic feedback alongside physical buttons and touchscreen controls.
The computer’s MCP gateway is intended to let users send data directly to Claude and ChatGPT without building a custom connector script. Coros also lists compatibility with heart-rate monitors, power meters, smart trainers, radar, lights and e-bikes, as well as services including Strava, Zwift, Komoot, RideWithGPS, TrainingPeaks and TrainerRoad. Its specifications list Bluetooth, Wi-Fi and ANT+ connectivity.
Voice and AI Join Ride Controls
The announcement combines several ways to interact with a bike computer: physical buttons, touch, haptics and voice commands. Voice access may be useful when riders would rather not operate a screen or buttons while riding, although the announcement does not provide independent testing of how well commands work in different conditions.
The MCP gateway is a notable software addition because it provides a direct route for sharing ride data with Claude and ChatGPT. That could interest riders who want to use AI services to examine training information, but Coros has not specified what data is sent, what analysis those services will perform or how the process handles user privacy. The device’s price and availability also give prospective buyers a concrete date to compare against other cycling computers.

How It Changes the Dura Solar
The Dura 2 Solar follows Coros’ Dura Solar, retaining its headline 120-hour battery rating and solar-assisted charging claim while changing the display, controls and software features. The new screen is 0.8 inches larger by the stated diagonal measurement, and the listed weight drops by three grams. Coros says the solar panel is at the bottom of the new display; on the earlier model it was at the top.
The announcement comes shortly after Garmin introduced its voice-controlled Edge 1060, as noted in the Cycling Weekly report. Coros’s MCP gateway is presented as a built-in connection for AI services. The source report says open-source connectors exist for some Garmin and Wahoo devices, but says those brands did not offer an official MCP gateway at the time discussed.
Coros lists compatibility with Shimano, SRAM and Campagnolo drivetrains, with drivetrain support for those systems marked as coming at the end of 2026. That timing is later than the computer’s planned November 3 launch, so buyers should distinguish between features listed at release and support scheduled for a later date.

Performance and Privacy Details
The announcement does not give independent test results for battery life, solar gain, touchscreen performance or voice recognition. It is also not clear how reliably voice commands will work with wind, traffic or other background noise, or whether all voice features require a phone connection.
Coros has not detailed the MCP gateway’s data permissions, retention practices or the specific information sent to Claude and ChatGPT. The source material also does not specify whether use of those services requires separate accounts or subscriptions. Finally, the stated compatibility list does not establish that every sensor, platform or drivetrain function will be available at launch; Coros lists some drivetrain support for late 2026.

The next stated compatibility milestone is Shimano, SRAM and Campagnolo drivetrain support at the end of 2026. Coros has not provided a more specific rollout date or further detail about software updates, AI-service integration or privacy controls in the source material.
