Marin Four Corners 2 - 2026

Midweek commute, weekend adventures. No problem for the Marin Four Corners, our steel-framed explorer that's as comfortable on the asphalt as in the dirt.

A double-butted 4130 CrMo steel frame and fork are designed to be comfortable on rough roads and handle fully loaded-touring and bikepacking. 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 suit riders between 4'11 perfectly" – 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.

New for '24, the Four Corners 2 takes all the elements that make the Four Corners fantastic and adds a Series 3 double-butted CrMo frameset, a simpler, wide-range SRAM 1x12 speed Apex drivetrain, and matching, powerful Apex 1 hydraulic disc brakes. The rubber meets the road/path/trail with wider, 44mm Vee Tire Quickstyx tubeless-compatible tires, and the frame can accept tires up to 50mm wide.
