Downhill Trails

Light Dirt Jump
Enduro

The San Quentin 2 is our mid-pack model that blends bang-for-your-buck value with kick-ass components. We’ve packed in a TranzX dropper post, an RockShox suspension fork, Shimano brakes and drivetrain, Vee Tire rubber and plenty of awesome Marin kit to create a bike you’ll love to rip, but that won’t shred your budget.

Technology

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

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.
