The Marin DSX 3 Gravel Bike is a versatile, fast and adventure-ready flat bar gravel bike designed for riders who want the speed and capability of a gravel bike with the familiar, comfortable riding position of a mountain bike. Finished in a striking Matte Light Blue/Orange/Chrome colourway, the DSX 3 is equally at home on busy city streets, winding country lanes, gravel tracks and light singletrack.
Built around Marin's lightweight Series 3 6061 aluminium frame, the DSX 3 combines responsive handling with excellent durability. The frame features a tapered head tube, internal cable routing, a relieved bottom bracket and a 142x12mm rear thru-axle for a stiff and confident ride. Generous tyre clearance allows the bike to run wide 700c x 44mm gravel tyres, providing extra grip and comfort when the road gets rough.
At the front, a carbon fork helps reduce weight while adding compliance over uneven surfaces. Integrated mudguard and rack mounts also make the Marin DSX 3 an excellent choice for commuting, bikepacking and longer-distance adventures.
Flat Bar Gravel Performance
Unlike a traditional drop-bar gravel bike, the DSX 3 uses a flat handlebar and MTB-style grips, giving you an upright, heads-up riding position and greater control on rougher terrain. This makes it particularly well suited to riders who enjoy the versatility of gravel riding but prefer the feel and confidence of a flat bar.
The SRAM Apex 1 12-speed drivetrain provides a wide range of gears for everything from fast road riding to steep gravel climbs, while the SRAM Apex 1 40T crankset keeps the setup simple and efficient. With a 1x drivetrain, there is no front derailleur to worry about, making gear changes straightforward and reducing maintenance.
Stopping power comes from SRAM hydraulic disc brakes, with 160mm rotors front and rear. Whether you're commuting through Liverpool traffic, descending a gravel track or tackling a long weekend adventure, the hydraulic braking system provides powerful, controllable stopping performance in a wide range of conditions.
The DSX 3 rolls on Vee Tire Co. Rocket Man 700x44mm tyres paired with Marin double-wall, tubeless-compatible aluminium rims. The generous tyre volume helps smooth out rough surfaces while providing plenty of traction across gravel, tarmac and light off-road trails.
