Marin Headlands 1 2025 Gravel Bike

Fully loaded bikepacking, fast and light off-road adventures, gravel and CX racing… or simply exploring your favorite tracks and trails. The Marin Headlands is a high tech, high-spec carbon fiber gravel and adventure bike that’s made to be lightning-fast, confidence-inspiring and super comfortable on all surfaces.

We’ve taken our own unidirectional carbon fiber frame, added mountain bike-inspired geometry, loads of tire clearance and a whole heap of mounting points for gear and fenders to create a super versatile, super capable all-terrain dart of a bike. Go 700c with room for up to 45mm tires or 650b up to 47mm.

The Marin Headlands 1 offers bags of fun, adventure and performance without the loftier price point of the mighty Headlands 2. Gravel-specific Shimano GRX groupset, GRX hydraulic brakes, Vee Tire Co tires and Marin wheels and finishing kit all add up to a whole mountain of fun and adventure.
