Four Corners 2
Marin
Gravel
Four Corners 2 is a steel gravel road bike (2024), by Marin. It is best suited to riders who prioritize comfort, confidence, and longer rides, leaning toward a comfort-leaning riding position, and is ready for gravel routes as well as pavement. Its profile is strongest in areas like good fit flexibility for dialing in rider position, a balanced ride feel between comfort and directness, and less emphasis on aero shaping than on all-round practicality. At the same time, compared with more specialized alternatives, the compromise is less emphasis on outright speed than speed-focused builds and a value score that depends more on priorities than pure price efficiency.
