The Marin Bolinas Ridge 2 is your gateway to real off-road riding, built for adventurous beginners and recreational mountain bikers who are ready to explore further and ride harder. With upgraded performance components, a modern trail geometry, and proven reliability, the Bolinas Ridge 2 is your perfect trail companion for discovering singletrack, navigating fire roads, or simply turning every ride into a new adventure.
At the heart of the Bolinas Ridge 2 is Marin’s Series 1 6061 aluminum frame, designed with a low standover height for easy maneuverability and rider confidence. It’s available with 27.5” wheels (sizes XS–M) and 29” wheels (sizes M–XL) to deliver the right fit for every rider. The frame features internal cable routing, forged dropouts, and chainstay-mounted disc brakes—a sleek, durable platform that’s trail-ready and built to last.
Up front, the SR Suntour XCM DS suspension fork offers 100mm of trail-smoothing travel, plus preload adjustment so you can fine-tune the ride based on your weight or terrain. Whether you're rolling through rocky sections or climbing rooty switchbacks, this fork handles it all with ease.
The bike features a Shimano Altus 3x8 drivetrain, offering 24 gears to take on steep climbs, fast descents, and everything in between. Matched with a SunRace 11-34T cassette and 42/34/24T crankset, you’ll have a wide range of gearing that keeps your cadence consistent and your legs happy.
One of the major performance upgrades on the Bolinas Ridge 2 is the addition of Clarks Clout hydraulic disc brakes. With 160mm rotors front and rear, these brakes offer powerful, consistent stopping power—especially useful when riding in wet or dusty trail conditions.
You’ll roll confidently on Marin double-wall alloy rims wrapped in 29x2.25” off-road tires (size-dependent), delivering a mix of grip, comfort, and durability across varying surfaces.
The cockpit is designed for control and comfort with a 780mm wide Marin riser handlebar, short 45mm stem, and Marin MTB grips. A sealed cartridge bottom bracket, nylon platform pedals, and Marin MTB saddle round out a build that’s ready to ride out of the box.
