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.

Technology
Five Frame Sizes

New for 2018 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.
Reviews
-
"If you’re a commuter or utility rider who wants to do some touring on the weekends, the Four Corners is solid candidate. With a change of tires it’s also a capable dirt-road explorer. A few short years ago a bike of this caliber this would have sold for much more. But despite its base-level designation, the Four Corners performs well above its price point. It’s so capable, in fact, that I often found myself inadvertently comparing it to bikes retailing for $500-$1000 more. Sure, those more expensive bikes might be a little lighter, and come spec’d with fancier components, but the Four Corners gives up nothing when it comes to function and versatility."

"If you appreciate an upright, comfort-oriented geometry, plus the ability to run big tires, the 2018 Marin Four Corners certainly looks like a good value."
-
"The mark of a good adventure bike is how easily it can go from dirt roads and gravel paths to the city streets of a daily commute. Marin's Four Corners bike is optimized for comfortable multi-terrain touring, with a long, tall frame that steers slowly and has extra braze-ons for storing cargo without sacrificing balance and speed."
-
"Four Corners is a recommendable, very attractive price and universal expedition bike."
-
"The Four Corners is a comfy, fun bike to ride over all terrains, equally at home loaded up with touring/bikepacking bags as it is at home on the daily commute."
