COROS DURA 2 SOLAR GPS Bike Computer

The DURA 2 SOLAR is COROS's flagship cycling computer, rebuilt from the ground up with a big 3.5" edge-to-edge touchscreen, a woven carbon and aluminium body that weighs just 99g, voice control, and the longest battery life of any GPS bike computer: up to 120 hours on a single charge, before the solar panel has even started topping it up.

Whether you're training to power, navigating a new gravel loop, or riding multi-day bikepacking routes, it's built to go the distance and look good on a premium bike while doing it.

Choose your option

• No Mount (Unit Only) – £429: For riders who already have a quarter-turn (Garmin-style) mount on their bike. No mount of any kind is included in this version.
• With Aluminium Standard Mount – £479: COROS's new sleek aluminium mount, with a three-prong interface underneath for a camera, radar or smart light.
• With Aluminium Out-Front Mount – £479: Out-front aluminium mount that tilts from -7° to +5° to suit integrated cockpits, also with a three-prong accessory interface.

Design & build

• Woven carbon fibre backplate and tapered aluminium alloy bezel
• Ultra-slim 5.7mm upper profile for a cleaner, more aero front end
• Just 99g (unit only), around 137g with mount
• IP67 water resistance for wet winter rides
• Quarter-turn mount interface – works with existing DURA and Garmin-style mounts
• UCI compliant (Article 1.3.006)

Display

• 3.5" (88.9mm) edge-to-edge colour Memory-in-Pixel (MIP) touchscreen
• 336 x 620 pixel resolution – 30% larger screen and 17% higher pixel density than the original DURA
• Anti-glare coating, optimised for readability in direct sunlight
• Responsive touch that works with gloves and in the rain

Three ways to control it

• Touchscreen: swipe between pages, pinch and pan maps, check sensor status and set alerts
• Buttons: a lap button on the left side, a start/stop/select button on the right, plus two pressure-sensitive haptic buttons built into the solar panel where your hands naturally rest
• Voice: windproof microphone and upgraded speaker – start and end rides, add points of interest, control media, change routes and more (hold the left button)

Battery & solar charging

• Up to 120 hours in All Systems GPS mode
• Up to 70 hours in Dual-Frequency GPS mode
• Monocrystalline solar panel: up to 2 hours of extra ride time for every hour of direct, bright sun
• USB-C charging – roughly 2.5 hours for a full charge, and the unit can be used while charging

Battery life depends on settings and feature use (navigation, music, backlight, sensors). Solar gain is quoted in strong direct sun; UK autumn and winter light will deliver much less.

Navigation & maps

• Free global maps, downloaded by region over Wi-Fi via the COROS app
• Street and trail names plus points of interest on the map
• Smooth swipe, pinch and pan, powered by an Ambiq Apollo 510 processor
