San Quentin 1
The Marin San Quentin 1 is for the aggressive hardtail trail rider looking for a blend between singletrack capabilities and extended air time.
This hardtail MTB features a Suntour XCM34 suspension fork, Vee Tire Co tires, Tektro disc brakes and a load of awesome Marin components to create a bike you’ll love to rip, but that won’t shred your budget.
Technology
Dirt jump inspired frame style: Taking cues from the Alcatraz, the San Quentin line up provides all the benefits of the DJ style with massive stand over, slick frame tubes and great paint jobSeries 2 & 3 aluminium frames: The San Quentin 1 features a Series 2 aluminum frame, with tapered head tubes, 3D forged drop outs, IS brake mounts, and semi-internal cable routing. The San Quentin 2 and 3 feature Series 3 aluminum frames, with more advanced tube forming, more complex dropouts, post mount disc tabs, full internal cable routing, and a boost 148mm thru-axle
Modern Trail Geometry: The slack head tube angle paired with a steep seat tube angle create a ride that will fly uphill with perfect front wheel precision but then descend like it’s on rails. The balanced rider position thanks to the steep seat tube puts your weight between the wheels for impressive climbing and handling on flats, while the slack front end and short rear center help to pull you through the rough descents and corners with an intuitive feel.
