Have you heard about the upgraded Marin Four Corners? If not, keep reading! It’s the new upmarket version of their popular adventure touring bike. Building upon the legacy of the Four Corners lineup, this iteration caters to discerning riders seeking versatility and performance.

The Original Steel Adventure Bike

The Four Corners has been a staple in Marin’s drop-bar lineup for decades, reinvented for the brand’s 2016 30th anniversary. These “Utilitour” adventure touring bikes have consistently been stout, steel steeds—touring bikes with a great sense of adventure—and have propelled riders on journeys as diverse as the weekday commute to transcontinental excursions.

Since 2018, Four Corners models have utilized size-specific wheel sizes for proper rider fit and balanced handling characteristics, loaded or unladen (XS & S = 650b, M, L, XL = 700c, which fits 4’11” and 6’4” perfectly). 

These bikes have tall headtubes to put the rider in a more upright riding position for greater visibility and for taking in the sights while additionally allowing for more frame carrying capacity, as comparatively larger frame bags can be used.

The Four Corners 2: Premium Features for Enlightened Riders

The upscale model returns after a seven-year hiatus, now as the Four Corners 2. It is oriented towards a more discriminating rider and built upon a Series 3 double-butted CroMo frame and fork, with front and rear thru-axles. It also has an SRAM Apex 1×12 speed drivetrain, hydraulic disc brakes, and tubeless-compatible rims and tires.

Geometry follows in the new Four Corners 1 tracks and is a bit more progressive than typically in the touring bike category, with 70°-71° headtube angles (depending on frame size). Seat tubes can accommodate dropper post routing for riders who want added control when riding off-pavement or to make it easier to put a foot down when stopping. Wide handlebars, at 440-460mm, give the rider additional confidence off-pavement and a bit more real estate to hang bags and mount accessories. 

An abundance of accessory mounts graces the frame, with two atop the toptube at the headtube, and three on the underside of the toptube. These mounts are great for those looking to have custom frame bags made, and Marin will provide a detailed placement “map” on the website.

Both wheel sizes of the Four Corners 2 models roll on 44mm wide tires, and frames now have clearance up to 50mm.
