Marin Headlands 2 2026 - Gravel Bike
The Marin Headlands 2 is named after the iconic Californian coastline, designed to embody the adventurous spirit of gravel riding. Its full unidirectional carbon chassis is designed for performance on mixed terrain, blending lightweight efficiency with rugged durability. The geometry takes inspiration from modern mountain bikes, pairing short chainstays with a longer top tube and short stem. This gives the Headlands 2 sharp handling on technical trails while keeping it comfortable and efficient on fast, open roads.
Key Features:
- Unidirectional carbon frame, Beyond Road geometry, clearance up to 700x45mm / 650Bx47mm
- Marin full carbon fork with tapered steerer and thru-axle
- Shimano GRX RX820 1x12-speed drivetrain
- Shimano GRX RX820 hydraulic disc brakes, 160mm rotors
- Marin aluminium double-wall tubeless-ready wheels
- Vee Tire Co. G-Sport 700x44mm tubeless-compatible tyres
- TranzX dropper post adds downhill confidence
- Available with 0% APR finance
The frame has clearance for 700x45mm or 650Bx47mm tyres, so you can adapt the setup to suit your rides, from fast-rolling gravel to more aggressive, trail-ready rubber. Internal cable routing keeps the look clean, while multiple mounting points mean the bike is ready for racks, mudguards, and full bikepacking loads. Whether you’re setting out for a day ride or a multi-day adventure, it’s built to carry what you need.
Equipped with Shimano GRX RX820 1x12 gearing, the Headlands 2 offers smooth, precise shifting with a wide 10-51T cassette that gives plenty of range for climbing and speed on the flat. Shimano GRX RX820 hydraulic disc brakes with 160mm rotors provide confidence-inspiring stopping power, whatever the weather. Rolling on Marin tubeless-ready aluminium wheels fitted with Vee Tire Co. G-Sport 700x44mm tyres, you get fast rolling performance with reliable grip and the benefits of tubeless set-up.
A standout feature is the TranzX dropper post, which adds confidence and control on steep or technical descents – something you don’t often see on gravel bikes. Finished with Marin’s Beyond Road finishing kit and a comfortable Marin Beyond Road Concept Elite saddle, the Headlands 2 blends efficiency with adventure-ready confidence.
From epic weekend gravel loops to loaded bikepacking expeditions, the Marin Headlands 2 is a carbon gravel bike that pushes boundaries, ready for wherever your rides take you.
