Marin Four Corners 1 (Sword) Gravel Road Bike
Midweek commute or weekend adventures? A three day audax or a 12 month round the world tour? The Four Corners 1 now comes with a fresh 2x9 MicroShift Sword drivetrain offering improved reliability and a wider range of useable gears. The butted 4130 CroMo 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.
Whatever you choose is no problem for the Marin Four Corners, our steel-framed explorer that’s as comfortable on the asphalt as it is in the dirt.
Life is about the journey, not the destination, and that's what the Four Corners is here for.
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 base Four Corners, along with traditional front triangle bottle mounts (three on sizes M-XL, two on XS-S) provide up to six bottle cage mounts total.
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.
STEEL IS REAL
The Four Corners uses butted and formed Series 1 4130 CrMo frames 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.
