I’m not sure what the general consensus is on the flat bar gravel bikes, but I think they are great. My bet is that many of our readers will insist that these new offerings are simply an throwback to some the mountain bikes of old, which definitely has some truth to it. But, it’s hard to argue with recent options that have been released with fair pricing and interesting specs. For newer riders, I suggest flat bar gravel bikes as they make way more sense than a drop bar rig. Mix in a nice build and adequate tire clearance and you’ve got a versatile ride that’s great for commuting, gravel rides, and mixed-terrain bikepacking.

The new 2021 Marin DSX is an entirely new flat bar gravel bike, joining the ranks of the Salsa Journeyman and Specialized Diverge, on a mission to make a comfortable platform for gravel and beyond. It’s based around Marin’s Series 3 6061 aluminum frame, a carbon fork, low standover, hydraulic disc brakes, and a 1x drivetrain—currently offered in two different builds (DSX 1 and DSX 2) to fit different budgets. Although the frame is missing all the usual mounting points we like to see, it does have rack and fender eyelets, as well as internal dropper post routing for the most extreme gravel exploration. The DSX comes stock with 700 x 45mm tires, but has room for 29 x 2.1″ knobbies and both the frame and fork use 12mm thru-axles.

The DSX 2 is the higher-end build of the two, although with a price tag of just $1,099 USD, it’s still quite affordable. The main difference being a complete Shimano Deore 12-speed drivetrain as well as Shimano branded hubs instead of the OEM forged aluminum hubs on the DSX 1.
