The Marin Bolinas Ridge 2 29" is designed to help riders build confidence off-road, combining a solid specification with user-friendly features. At its core is a Series 1 6061 aluminium frame with low standover for easy mounting and dismounting, plus geometry tailored for stable, predictable handling on trails and tracks.
Up front, the SR Suntour XCM DS fork provides 100mm of suspension travel with preload adjustment, helping absorb bumps and uneven surfaces while keeping steering sharp and controlled. The 29” wheels on larger frame sizes (and 27.5” on smaller ones) ensure the right fit for every rider, offering either fast rolling or agile handling depending on size.
Shimano’s reliable Altus 3x8 drivetrain delivers a wide range of 24 gears, giving plenty of options for tackling climbs and rolling terrain. Stopping power is handled by Clark’s Clout hydraulic disc brakes with 160mm rotors, offering consistent and controlled braking across conditions.
The finishing kit is equally trail-ready, with a wide 780mm riser bar for improved stability and control, a Marin MTB saddle designed for comfort, and durable alloy wheels laced with stainless steel spokes. The double-wall rim construction provides extra strength for off-road riding, while the sealed cartridge bottom bracket adds long-lasting reliability.
For riders who want a bike that offers performance and value, the Bolinas Ridge 2 is a step up from the entry-level model, making it a great choice for exploring trails, learning new skills, or enjoying recreational off-road riding.
