Midweek commute or weekend adventures? A three day audax or a 12 month round the world tour? The Four Corners 1 now comes with a fresh 2x9 MicroShift Sword drivetrain offering improved reliability and a wider range of useable gears. The butted 4130 CroMo steel frame and fork are designed to be comfortable on rough roads but to also handle fully loaded touring and bike packing. We’ve included six bottle mounts, rack and fender eyelets, lowrider fork mounts, generous tire clearance and disc brakes to set you up for all conditions and all terrain.
Whatever you choose is no problem for the Marin Four Corners, our steel-framed explorer that’s as comfortable on the asphalt as it is in the dirt.
Life is about the journey, not the destination, and that's what the Four Corners is here for.
