First Impression: Marin Four Corners

Marin designed the Four Corners and Four Corners Elite for the daily commute and the weekend adventure, and it couldn’t be more on point. I’m testing the lower priced model, with an MSRP of $1100. It offers all the bells and whistles for fully-loaded touring in an affordable package. The Four Corners is an all-steel frame with mounts for a front and rear rack, fenders and three bottle cages.

Saddling up, I immediately noticed the upright riding position facilitated by the long headtube. The bars sit higher than what I’m used to and have a 20-degree flare to the drop. On other bikes, I’ve trended toward riding primarily on the hoods and tops, but the Marin’s upright position had me comfortably riding in the drops for long stretches of rolling hills and rail trails—a welcome change. The reach on the size small frame was a little long for me, so I put on a 20 mm shorter stem.

To get a sense of the bike’s touring capabilities, I added fenders and a front rack and loaded it down with gear for a mixed-surface tour from Cumberland, Maryland, to Pittsburgh. The ride included crushed limestone rail trail, rolling hard roads, dirt roads and railroad ballast. I carried my weight low on the front rack and the bike handled very well while weighted down.

On the small-sized frame, I was unable to include a water bottle underneath the downtube because it hit the fender. Though I haven’t tried yet, I’m speculating that the tire will come very close to hitting even a short bottle without fenders. On my trip, I used a stem-mounted cage for a third bottle.

The other two bottle mounts are placed so they’re easy to reach for day-to-day use, but they’re not in an ideal location for a frame bag. I zip-tied a cage lower on the downtube, closing up the unused space and allowing room for my frame bag.

I found the stock Schwalbe Silento 700c x 40 mm tires to be an appropriate spec, rolling well in a variety of terrain and adequately burly, so I wasn’t overly concerned with getting a flat. The Four Corners has clearance for up 45 mm tires with fenders or 29 x 2.1 knobby tires without fenders.

The Shimano Alivio 9-Speed with 12-36T gearing was adequate while weighted down over Pennsylvania’s rolling hills, but I’d go with a lower gear range for an extended, fully-loaded tour with sustained climbs.


I was thrilled with the stock WTB Volt Sport saddle. One of the biggest pains of rail trail riding are the long, flat sections of saddle time. The WTB is comfortable and supportive and I didn’t find myself sitting gingerly.
