Frame and Construction
The Marin Bolinas Ridge 2 29 gloss black/blue mountain bike features a solid construction based on a Series 1 6061 aluminum frame. The frame is designed for 29-inch wheels, which provide better stability and smoothness when riding on rough terrain. The low standover design and a bottom bracket shell width of 68 mm with 135 mm forged rear axle dropouts contribute to durability and comfort. The specially designed disc brake mounts on the rear triangle ensure optimal braking conditions.
Drivetrain and Gears
The Marin Bolinas Ridge 2 drivetrain is based on 24 speeds, allowing adjustment to various terrain conditions. Shimano Altus 3x8-Speed shifters, combined with a Shimano FD-TY700 front derailleur and Shimano Altus 8-Speed rear derailleur, provide smooth and precise gear changes. The crankset consists of aluminum crank arms and steel chainrings with 42/34/24T teeth, enabling efficient power transfer.
Wheels and Tires
The Marin Bolinas Ridge 2 is equipped with durable wheels featuring double-walled aluminum alloy rims. The wheel diameter is 29 inches, which, combined with 2.25-inch wide MTB tires, offers excellent traction and cushioning on uneven surfaces. Forged alloy hubs with disc mounts and steel, anti-corrosion spokes increase the overall durability of the set.
Braking System and Suspension
Safety and control during riding are ensured by Tektro HDM275 hydraulic disc brakes, with 160 mm rotors both front and rear. The SR Suntour XCM DS suspension fork, with 100 mm travel and preload adjustment, helps to overcome terrain irregularities, enhancing comfort and control.
Additional Components and Ergonomics
The Marin Bolinas Ridge 2 bike is equipped with components that provide comfort and durability, such as the Marin MTB saddle, Marin 31.8 Riser handlebar with a width of 780 mm and a rise of 12 mm, and an aluminum seatpost with a diameter of 27.2 mm. Marin MTB grips with closed ends and the included pedals complete the functionality of this model, making it an excellent choice for off-road riding enthusiasts.
Product Details

6061 aluminium frame
The 6061 aluminium construction creates a rigid foundation for the entire bike, ensuring stability while tackling uneven terrain. The use of this alloy translates to increased resistance to everyday stresses and dynamic maneuvers in the field. When riding on demanding trails, the frame effectively transfers pedalling force and supports control over the bike even at high speeds.

SR Suntour XCM DS suspension fork
The SR Suntour XCM DS suspension fork effectively absorbs impacts while riding on rocky trails and bumps. The 100 mm travel allows for an active response to changes in the terrain, minimising shocks transmitted to the handlebars. Preload adjustment is particularly useful during dynamic riding when precise tuning of the suspension to current trail conditions is essential.

Tektro HDM275 hydraulic disc brakes
Precise stopping of the bike in demanding situations is ensured by Tektro HDM275 hydraulic disc brakes, present both at the front and at the back. The use of a 160 mm diameter disc translates into reliable control over speed during steep descents and when riding on uneven terrain. Even during sudden braking on challenging trails, the system maintains bike stability and supports safe navigation of obstacles.
