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. Marin updated the geometry based on biometric t data, and for 2021 offer ve different frames sizes with size proportionate 650B or 700C wheels to properly t riders between 4’11” – 6’4”. The bars are set high for all-day comfort and heads-up visibility in tra c, 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.
Dedicated commuting
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.
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
New for 2021 are fork leg bottle or accessory cage mounts, along with traditional front triangle bottle mounts (three on sizes M-XL, two on XS-S) for up to six bottle cage mounts total.
Fender / rack mounts
The Four Corners has separate fender and rack mounts on both the frame and fork to fit a variety of aftermarket accessories securely and without interference with one another.
Steel is real
The Four Corners uses a double butted and formed 4130 CrMo frame specially tuned for loaded touring with upright geometry for comfortable and efficient all-day rides.
Disc brakes
Disc brakes provide smooth, controlled stopping in all conditions with minimal maintenance.
