The Marin San Quentin 1 in size 15” Small and eye-catching Teal/Pink colorway is a nimble and versatile hardtail mountain bike designed to bring fun and confidence to riders stepping into trail riding or urban exploration. It strikes the perfect balance between performance, comfort, and style, making it ideal for beginners and intermediate riders alike.
Frame & Geometry
Built with Marin’s Series 1 6061 aluminum alloy frame, the San Quentin 1 offers a lightweight yet robust foundation for years of riding. The frame geometry leans toward a balanced and slightly relaxed setup, with a moderate head tube angle and a comfortable reach, allowing riders to feel stable on climbs and responsive on descents. Its compact 15” frame size fits smaller riders perfectly, optimizing control and maneuverability.
Wheels & Tires
The bike rides on 27.5-inch wheels, providing the sweet spot between agility and rollover ability. These wheels excel at darting through tight corners on technical singletrack while still rolling smoothly over rocks and roots. The tires are designed with a trail-ready tread pattern, offering enough grip to boost rider confidence on diverse surfaces.
Drivetrain
Featuring a Shimano 2x8-speed drivetrain, the San Quentin 1 provides 16 gears, offering riders plenty of options to tackle varying terrain—from steep climbs to fast flats. The dual chainrings give additional control over cadence, making it easier to maintain speed or torque when needed. The Shimano components ensure reliable and crisp shifting, reducing frustration on the trail.
Suspension
The front end sports a Suntour XCT suspension fork with 100mm of travel, which smooths out bumps, roots, and rough terrain. This suspension fork improves comfort and control by absorbing trail chatter, reducing rider fatigue during longer rides, and increasing traction on technical features.
Braking System
The bike uses mechanical disc brakes that offer dependable stopping power with straightforward maintenance. While not hydraulic, these brakes perform well in most conditions, giving riders the confidence to handle both urban stops and trail descents.
Comfort & Control
Wide flat handlebars enhance leverage and steering precision, helping riders navigate tricky trail sections.
Ergonomic grips and a comfortable saddle with an adjustable seatpost provide a tailored fit for smaller riders, encouraging longer and more enjoyable rides.
Durable platform pedals provide stable footing for varying skill levels.
Design & Aesthetics
The bike’s Teal/Pink color scheme is vibrant and playful, making it stand out on trails and streets alike. The smooth welds and clean cable routing complete the polished look, showing attention to detail.
