Four Corners 2 2026

The Marin Four Corners 2 2026 is a versatile gravel/mountain/commuter bike. Made from double-butted 4130 CrMo steel, the frame and fork deliver a smooth, confident ride on rough roads while easily handling the demands of fully loaded touring and bike-packing.

Packed with features like, six bottle mounts, rack and fender eyelets, lowrider fork mounts, generous tyre clearance, and dependable disc brakes, this bike is ready for any condition and every adventure.
