Marin San Quentin 1 Bike 2025Hardcore hardtail. Soft on the wallet. The Marin San Quentin 1 is the bang-for-your-buck trail bike that looks and rides like something twice the price. The Series 2 6061 aluminum frame is double-butted, internally routed, and built for the kind of riding that would embarrass most bikes at this price point. An SR Suntour XCM34 130mm coil fork, Micro Shift 1x9 drivetrain with clutch derailleur, Tektro hydraulic disc brakes, and Delium Versatile 2. 5" tubeless-ready tires make this a genuinely capable trail hardtail from the jump.
