    The Four Corners is built for the adventure rider looking to explore deep off of the beaten path, sleep outdoors, and be ready for whatever pavement, dirt road, or light singletrack is around the next corner. The heads-up bar position and generous braze-ons that make it possible to live on the bike for days at a time are equally at home on the daily commute.

    The Four Corners series is perfectly suited to today’s commute and tomorrow’s touring adventures. The butted 4130 CrMo steel frame and fork are designed to handle fully loaded touring, with up to six bottle mounts, rack and fender eyelets, lowrider fork mounts, generous tire clearance and disc brakes to bring it all to a stop. Four Corners geometry is based on biometric fit data, and we offer five different frame sizes with size proportionate 650B or 700C wheels to properly fit riders between 4’11” – 6’4”. The bars are set high for all-day comfort and heads-up visibility in traffic, with mountain steering geometry capable of taking you down whatever path your destination requires. Carry a laptop and change of clothes during the week, a tent and camp stove come Saturday morning. Get to work, and get out of town.

    PERFECT FOR

    • TOURING
    • BIKEPACKING
    • DEDICATED COMMUTING

    WHEEL SIZE: 650B (XS,S) or 700C (M,L,XL)
    SIZE RANGE: XS, S, M, L, XL
    COLOR: Satin Black/Maroon, Gloss Green/Tan

    Marin uses biometric fit data based on statistics of people’s body proportions to develop the proper fit and weight distribution on each size of the Four Corners.
    Using this data, we created five bike sizes across two wheel sizes to fit people from 4’11” to 6’4” without compromising the ride.

    The Four Corners has been updated with additional braze-ons for versatility and frame bag compatibility. Beyond the front and rear rack and fender mounts for the commute, there are now two bottle or accessory cage mounts on the base Four Corners fork, a bottle mount on the bottom of the downtube, and traditional
    front triangle mounts as well (three on sizes M-XL, two on XS-S) for up to six bottle cage mounts total for the thirstiest adventure.

    With clearance for 47mm 700C/650B tires with fenders or 2” mountain tires without, the Four Corners is designed with mountain bike capabilities in a drop bar package.
    Navigate singletrack confidently on the way to work or en-route to that perfect campsite.
