Marin San Quentin 1 29 - Grey/Black

Season:2026

Brand:Marin

Code:7406840GRYFADE

Developed in conjunction with freeride legend Matt Jones and taking its name from the most rough and tumble piece of Marin County, the San Quentin collection lives up to the notoriety of the namesake maximum security California State Prison. Blending the strength an style of our Alcatraz dirt jump frame with the natural trail savvy of the best hardtails, the San Quentin family of aggressive trail hardtails is the perfect mash-up for the modern trail rider.

The San Quentin 1 is our bang-for-your-buck hardcore hardtail that looks and rides like a bike twice the price. Because why should fewer dollars in the bank mean fewer good times on the trails?

We've packed in an SR 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. And we've given it a bad-ass paint job that'll cut it alongside those big-bucks bikes.

SERIES 3 AND 2 ALUMINUM 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.

ISCG TABS

San Quentin 2 and 3 models feature ISCG 05 tabs for easy chain retention device installation for rowdier riders.
