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 bikepacking. marin Have included six bottle mounts, rack and fender eyelets, lowrider fork mounts, generous tyre 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. Marin have 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 6'5".
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. 45mm wide multi-surface Vee GP tyres are up for wherever your adventures take you, while the supremely reliable MicroSHIFT Sword 2 x 9 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.
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.
Tall Head tubes - 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.
