This year is Marin Bikes’ 30th anniversary, and it marks the introduction of an all-new “utilitour” model, the Four Corners. The neutral gray steel frame gives the bike a timeless look, while disc brakes, wide tire clearance and an upright riding position keep pace with cyclists’ expectations for adventure touring and bikepacking.
What piqued my interest in this bike was its Gemini, do-it-all attitude packaged at an approachable price point. The Four Corners is equipped with a Shimano Sora 50/39/30 crank and 12-36 cassette, wide Schwalbe Silento 700×40 tires and the stopping power of Promax Render 160 mm disc brakes. The bike’s tour-ready spec is rounded out with mounts for racks front and rear, fenders and three water bottles.
Marin also offers the upgraded Four Corners Elite model with a SRAM 1×11 drivetrain and hydraulic disc brakes for $2,300.
The Four Corners was designed with a long top tube—21.8 inches on the small—but also a long stem offering ample room for adjustment. An upright riding position is facilitated by a tall head tube, and the Marin bars have a 20-degree flare to the drop, which allows for a natural hand position that opens up your core. This had me in the drops more than usual, and I’ll struggle to return to a bar without flare.
On a weekend tour I split my gear between a front rack, frame pack and seat bag. It can be a struggle to fit standard-sized frame packs on small-sized frames, but the long top tube opens up the interior space, expanding storage options for shorter folks. The tires are a good middle-of-the-road rubber, offering adequate rolling speed on hard roads and off-road traction. Best of all they’re stout, making them a good fit in any terrain where you’re susceptible to punctures.
While the stock tires were capable on smooth sections of singletrack and confident when loaded down with touring gear, there’s ample clearance for swapping to larger tires: up to 700×45 with fenders or 29×2.1 without.
The bike remained poised across varying terrain, its balance un-phased by rutted dirt roads and chunky railroad ballast, proving competent to carry the weight for an extended tour. I found the gear range to be ample for touring Pennsylvania’s rolling hills, but an easier gear may be advantageous on an extended tour with sustained climbs.
For days between 45 and 85 miles, the WTB Volt Sport saddle was comfortable and supportive, even on long sections of rail trail. “The Four Corners was designed for the rider who is looking for a versatile, modern take on a touring bike,” said Chris Holmes, brand director for Marin Bikes. “[It’s] one that is equally at home with a weekday commute as it is on a week-long adventure.”
For the city dweller, it fills the niche for everyday commuting needs, and for the adventure seeker, the large tire clearance and touring capability encourages exploring on gravel and dirt. As cyclists, what tales would we have to share if everything went as planned? The Marin Four Corners is ready for a change of route and a story to tell.
