Marin San Quentin 3 2023 Frame Kit

The San Quentin is for the aggressive hardtail trail rider looking for a blend between singletrack capabilities and extended air time.

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.

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.

Designed around 27.5” wheels front and rear using a 130mm suspension fork.
