The Marin Bolinas Ridge 2 takes the solid foundation of its predecessor and supercharges it with upgraded components for even more fun, control, and confidence on the trail. Designed for riders eager to venture off the beaten path, it blends trail-focused capability with everyday reliability—perfect for everything from local loops to full-day dirt adventures.
At the heart of the Bolinas Ridge 2 is a Series 1 6061 aluminum alloy frame, delivering a lightweight yet rugged platform engineered for durability and responsive handling. It’s optimized with size-specific wheels—27.5" on XS to M and 29" on L and XL sizes—to ensure the perfect blend of agility and rollover capability. A low standover height enhances maneuverability for newer riders, while internal cable routing keeps things clean and protected from the elements.
Taming rough terrain up front is the SR Suntour XCM DS suspension fork, offering 100mm of coil-sprung travel with preload adjustability. Whether you're rolling over roots, ruts, or rocks, this fork keeps your front end stable and under control.
An upgraded Shimano Altus 3x8-speed drivetrain offers a wide gear range to conquer climbs, cruise descents, or hammer out flat trails. Paired with a SunRace 11-34T cassette and steel 42/34/24T triple chainrings, it gives you dependable, versatile shifting wherever your ride takes you.
Where the Bolinas Ridge 2 truly stands out is in its braking power. Clarks Clout hydraulic disc brakes replace the mechanical systems found on earlier models, offering strong, consistent braking performance in all conditions—whether dry, muddy, or wet.
Mounted on durable Marin double-wall alloy rims, the 2.25” wide off-road tires grip confidently across loose, packed, and muddy trails, keeping you in control without sacrificing comfort.
The cockpit features a modern trail setup with a 780mm riser handlebar, 45mm short stem, and Marin MTB grips, delivering excellent leverage and stability when navigating twisty trails or rough descents. A comfortable Marin MTB saddle, sealed cartridge bottom bracket, and rugged nylon platform pedals round out a bike that’s built for real riding.
