MTB-STYLE GRAVEL BIKE
The Marin DSX FS is a versatile flat bar gravel bike designed to satisfy the adventurous spirit of mountain bikers with front suspension and a dropper post for off-road riding. It excels on long-distance commutes, gravel rides, and exploration of mixed terrain, offering a comfortable, upright riding position and the capability to handle dirt paths and light singletrack.

STABLE AND CAPABLE
Tackle descents with confidence aboard the DSX FS. Its mountain bike-inspired geometry, 60mm-travel air-sprung fork, and clearance for 700x45mm tires ensure a stable and controlled ride on loose gravel or technical sections. Tubeless-ready rims and tires enhance comfort and puncture resistance, making this bike a reliable companion for your off-road adventures.

BUILT TO EXPLORE
The DSX FS features a lightweight and durable Series 3 6061 aluminium frame, now featuring a UDH (Universal Derailleur Hanger) for improved drivetrain protection and easy replacement, with internal routing for a clean, modern look. Flat mount disc brakes and thru-axles provide reliable stopping power and security, while rack and fender mounts make it easy to customize the bike for commuting or loaded touring.

DROPPER POST
TranzX YSP38-KL dropper post lets you adjust saddle height on the fly, with smooth travel, lightweight build, and size-specific precision.

MARIN: ROOTED IN MTB
Marin's roots are tangled with the very beginnings of mountain biking. Founded in Marin County, California, the birthplace of the sport, this rich heritage fuels their passion to this day. Now, Marin pushes those boundaries further with riders like Matt Jones, constantly innovating to redefine what's possible on mountain and gravel bikes.
