Its dialed frame geometry means it is perfect to pin it on a singletrack or down rocky downhills, yet light enough that it’s not going to destroy you when riding to the top.

- SAN QUENTIN 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.
