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.
