Midweek commute, weekend adventures. No problem for the Marin Four Corners, our steel-framed explorer that’s as comfortable on the asphalt as it is in the dirt.
A butted 4130 CrMo 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.
Don’t be fooled, that classic frame material doesn’t mean low-tech. We’ve used biometric fit data to offer five different frame sizes, with size-matched 650b or 700C wheels to perfectly suit riders between 4’11” – and 6’4”. A high front-end creates all-day comfort and heads-up visibility, off-road-ready geometry means you won’t skip a beat when you head off the asphalt and explore Beyond Road.
40mm wide multi-surface Vee GP tires are up for wherever your adventures take you, while Shimano's supremely reliable Sora 3x9 drivetrain ensures that you'll always have the right gear ratio. Finally, Tektro Spyre-C mechanical disc brakes deliver controlled braking, even when riding fully loaded.

Technology
Five Frame Sizes
The Four Corners is available in five frame sizes to fit riders 4’11 to 6’4” without compromise. For proper fit and bike handling sizes XS and S use 650B wheels, sizes M, L, and XL use 700C.
Bottle / Gear Mounts
Fork leg bottle or accessory cage mounts on the Four Corners, along with an abundance of gear mounts within the front triangle, meaning that you can carry pretty much anything you want.
Tall Headtubes
The Four Corners is built around a tall headtube, allowing for more frame carrying capacity (larger bags), great rider visibility for taking in the sights, as well as the ability to utilize the multiple positions on the drop bars for all-day comfort.
Disc Brakes
Disc brakes provide smooth, controlled stopping in all conditions with minimal maintenance. Especially important when riding a fully loaded bike.
Steel Is Real
The Four Corners uses butted and formed Series 1 4130 CrMo frames and CroMo forks specially tuned for loaded touring with upright geometry for comfortable and efficient all-day rides.
Generous Tire Clearance
The Four Corners 1 can accommodate tires up to 45mm wide.
Dropper Post Compatible
The Four Corners offers a port on the lower part of the seat tube, allowing the installation of an aftermarket dropper post. Droppers are great at adding clearance when riding technical trails, or for simply putting a foot down while stopped at a light.
