The Marin Bolinas Ridge is your ticket to the world of mountain biking. Engineered for recreational riders who crave off-road excitement, it’s a confidence-inspiring hardtail with real trail performance, blending durability, comfort, and modern MTB geometry for all-day fun on singletrack and dirt trails.

At the core is a Series 1 6061 aluminum frame, designed for both 27.5" and 29" wheels depending on frame size, ensuring a perfect fit for every rider. A low standover height provides better control and easier mounting and dismounting, while the chainstay-mounted disc brake design keeps the rear end clean and modern. With forged 135mm dropouts, fender and rack mounts, and a 68mm bottom bracket shell, the Bolinas Ridge is ready for the trail, commute, or anything in between.

The SR Suntour XCE suspension fork offers 100mm of travel and preload adjustability to soak up bumps, roots, and rocks, giving you more confidence and control on uneven terrain. Matched with Marin double wall alloy rims and 2.25” wide MTB tires, the wheelset delivers solid traction, cushioning, and performance, whether you're carving corners or rolling over obstacles.

A Shimano Tourney 3x7 drivetrain gives you 21 speeds to tackle steep climbs, flowing descents, and everything in between. The triple crankset (42/34/24T) and 11-34T SunRace cassette offer a wide gear range, making it easy to find the right cadence for any trail.

Braking duties are handled by Power CX7 mechanical disc brakes, delivering consistent, reliable stopping power in all conditions with Shimano-compatible pads and 160mm rotors front and rear.

Control and comfort are key on the trail, so Marin has equipped the Bolinas Ridge with a 780mm-wide riser handlebar, short 45mm alloy stem, and closed-end MTB grips—ideal for stability, agility, and comfort. The build is rounded out with a Marin MTB saddle, a 27.2mm alloy seatpost, and durable nylon platform pedals, so you're ready to ride straight out of the box.
