2025 Marin Headlands 1 Gravel Bike in Silver

Named after one of the most iconic sections of coastline and Insta-inspiring gravel riding of the American West, the Marin Headlands embodies everything about this beautiful and rugged terrain. A full unidirectional carbon chassis is purpose- built for multi-surface adventures, be they short days or long weeks in the saddle. The 1x specific construction of the frame means short chainstays that still fit up to 700x45mm/650Bx47mm tires, and paired with the longer top tube and shorter stems the bike takes cues from modern mountain bikes on technical off-road trail, while stillmaintaining a comfortable, fast, and efficient ride on flatter terrain. Internal housing routing and tons of mounts on the frameallow you to fit the bike with anything from water and tubes, to a full custom frame bag from your favorite maker using the attachments found around the front triangle, while conventional rack and fender mounts can transition the bike into a capable winter commuter.
Fully loaded bike-packing, 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 Main Headlands 2 is our no-compromise, top-spec, top-performance gravel and adventure bike. Gravel-specific Shimano GRX 800 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. Last but not least, we’ve added a TranzX dropper seat post to really push you and your Headlands’ limits on the trails
