Product Details - Marin Dsx 3 Flat Bar Gravel Bike 2025 Blue

The Marin DSX is everything you want from a modern, flat-bar gravel bike. Zippy aluminum frames, compliant forks, heaps of tyre clearance, low standover, dropper post compatibility and a whole load of options for bags and fenders.

Taking inspiration from the Gestalt X drop bar line, we made the DSX to feel like an MTB but still cut it on all of those adventures that would normally demand curly bars.

The top offering in the DSX rigid fork lineup, the new addition to the line is built around the same Series 3 frames and carbon fork as the DSX 2, but with SRAM's wide-range Apex 1 x 12 speed drivetrain and DB-300 hydraulic disc brakes and Vee Tire's Rocketman tires, which offer a bit more bite.
