Frame and Construction

The Marin San Quentin 1 29 gloss tan/black/red mountain bike is a model designed for off-road riding enthusiasts seeking solid technical solutions. The frame, made of 2 6061 series aluminum with double-butted walls, ensures lightness and durability, while internal cable routing adds aesthetics and functionality. The 141 mm wheelbase and 73 mm threaded bottom bracket are features that emphasize the stability of the construction and its adaptation to riding in rough terrain. The bike is also equipped with an SR Suntour XCM34 fork with Boost 15x110 mm spacing, providing 130 mm of travel and better control when overcoming obstacles.

Wheels and Tires

This model features 29-inch wheels built from Marin aluminum double-walled rims. The rims are designed for disc brakes and compatible with tubeless systems, which increases their durability and riding comfort. The Vee Tire Co. Flow Snap tires, sized 29x2.6 inches and made from an MPC compound, provide excellent grip and stability on various surfaces. The spokes are made of black 14G stainless steel, and the hubs are forged alloy with sealed bearings, ensuring longevity and reliability in all conditions.

Drivetrain and Brakes

The use of a microSHIFT 1x9 drivetrain with SL-M9195-R shifters and an RD-M9195M rear derailleur with clutch function allows smooth and precise gear changes. The Marin crankset integrated with a 32T steel chainring and a SunRace cassette with an 11-46T range enable optimal speed adjustment to terrain conditions. Tektro M275 hydraulic disc brakes with 180 mm rotors provide effective braking, which is crucial on steep descents and at high speeds.
