The San Quentin 20 is for riders growing up at the local bike park and cruising around the neighborhood that want a kid-sized bike with adult-sized performance.

Series 2 Aluminum Frame
Features a Series 2 aluminum frame with a tapered headtube, 3D forged dropouts, IS brake mounts, semi-internal cable routing and 135mm open dropouts.

Dirt Jump Inspired Frame Style
Provides all the benefits of DJ style with massive standover, slick frame tubes, and a hot paint job.

Modern Trail Geometry
A slack headtube angle paired with a steep seat tube angle creates a ride that will fly uphill, yet descend like it's on rails. The balanced rider position puts the rider weight between the wheels for steady climbing and handling on flats, while the slack front end helps to add higher speed stability through turns and rough patches.

1x Wide-Range Drivetrains
Modern 1x drivetrains give the rider the benefits of shifting simplicity and chain retention.
