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.
