Why Choose the Marin Four Corners 1?
🚲 Adventure-Ready Steel Frame
Crafted from Series 1 butted 4130 CrMo steel, the frame and fork deliver a plush ride that soaks up rough roads and gravel tracks while staying stable and responsive under load. The tall headtube gives you a comfortable upright riding position, increasing visibility and room for large frame bags.
🔧 Tour-Proven Features
With six bottle cage mounts, rack and fender eyelets, and lowrider fork mounts, this bike is ready for full touring setups, minimalist bikepacking, or long-distance gravel rides. Roomy tire clearance up to 45mm and disc brakes make it suitable for all conditions—from city streets to forest trails.
⚙️ Reliable & Capable Drivetrain
The microSHIFT Sword 2x9-speed groupset offers a dependable wide-range gearing system built specifically for adventure cycling. Paired with a 46/29T crankset and 11-38T cassette, it ensures you're always in the right gear—whether you're climbing steep hills or cruising loaded descents.
