Marin Four Corners 1 (SORA)

Built for the Commute. Ready for the Adventure.

The Marin Four Corners is your all-in-one adventure machine, built with a tough steel frame that feels just as at home on city streets as it does on gravel roads and backcountry trails.

Its butted 4130 CrMo steel frame and fork are designed for all-day comfort, whether you're hauling gear on a bikepacking trip or loading up for your daily commute. With six bottle mounts, rack and fender mounts, lowrider fork compatibility, and clearance for large tires, it's fully equipped for any journey in any conditions.

Classic in appearance but modern in fit, the Four Corners is offered in five frame sizes, each paired with size-specific 650b or 700c wheels to suit riders from 4'11" to 6'4". Its tall front end provides a relaxed, upright riding position, while its off-road geometry keeps you stable and confident when the pavement ends.

40mm Vee GP tires handle a variety of surfaces with ease, while Shimano’s reliable Sora 3x9 drivetrain gives you all the gears you need. And with Tektro Spyre-C mechanical disc brakes, you’ll have consistent stopping power—even when fully loaded.
