Marin County California is regarded as the birthplace of mountain biking. With niche communities back then shaping what it is today, and with Marin Bikes' inception coming shortly after, the company has deep roots in the sport and now offers many styles of bikes to suit off-roaders and commuters alike.

The San Quentin 1 is Marin's 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.

Technology

Series 3 & 2 Aluminium Frame

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

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 a sexy paint job.

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.
