I’ve had the Marin Four Corners for about 3 months now but i havent had a chance to tour with it. Recently, a couple of friends and i had a short multiday trip up north and used this bike for that purpose.
For starters, the Marin Four Corners (check the specs here https://www.marinbikes.com/bikes/2019-pavement-drop-bar-utilitour-four-corners) was designed for bikepacking expeditions.
Made of chromoly steel, lots of mounting points for racks and cages, the frame also features varying wheelsizes depending on the size you’d get. In my case, i got the small size with 650b wheels. In terms of drivetrain, it sports Shimano sora 3×9 components with 50-39-30 upfront and 11-34 for the sproket. For stopping power, it has the TRP spyre mechanical brakes. the rest of the pieces are typical OEM components with the exception of the tires which are wtb resolutes (650bx42)
In terms of the ride, the Marin four corners reminded me of the Surly Disc Trucker on 650b wheels-slow yet the low bb height and chainstay length gave you sure footed stability during climbs. While i haven’t loaded this much as i packed light during the tour, i felt that the bike has a livelier feel when loaded with racks and panniers.
With regard to gearing, i felt that this was adequate giving a wide range of gear ratios, the 3×9 sora can definitely be a good option for long haul touring. while it is the first time ive used TRP mech brakes, there’s nothing really special about them. it does the stopping with fine modulation. One of the interesting things about the stock build is the compact 12 degree flared drops which to me were comfortable despite the sizing (mine had 40mm width). It reminded me of the soma condor in terms of comfort as you would prefer to stay on the drops while cruising.
While the recent trip ive had gave me an idea of the comfort and adequacy of the Marin four corners for touring, what i look forward doing with this bike is some off road expeditions as well as loaded trips using racks/panniers.
Overall, similar to the Marin Pine mountain, the Four corners’ specs are value for money for a built bike which may appeal to those interested in starting their own expeditions on two wheels without breaking the bank.
