2026 Marin San Quentin 1 Mountain Bike
The 2026 Marin San Quentin 1 is built for riders who want to shred
everything from pumptracks and jump lines to aggressive trail sessions.
Combining the playful pop of a dirt jumper with the stability of a modern
trail bike, the San Quentin 1 delivers confidence, durability, and progression.
Made to Shred
Featuring a tough Series 2 aluminum hardtail frame, the San Quentin 1
is designed for riders who push limits. Internal cable routing and dropper-post
compatibility make it future-upgrade ready, while its robust construction
ensures it can handle repeated abuse.
Modern Trail Geometry
A slack head tube angle paired with a steep seat tube creates a bike that
climbs efficiently and descends with confidence. The steep seat tube centers
the rider for balance on climbs, while the short rear end and slack front
inspire control through corners and rough terrain.
Trail-Tuned Performance
With 130mm fork travel, size-specific frames, a reliable
Microshift 1x9 drivetrain, and clearance for wide tires,
the San Quentin 1 thrives on flickable handling, side hits, and aggressive
trail riding.
