Marin San Quentin 2 27.5 - Blue-Black

Marin San Quentin 2 27.5 – Blue-Black – Dirt Jumper Swagger, Trail-Bike Heart

Hardtail meets hard-hitting. The San Quentin 2 blends dirt jump heritage with modern trail geometry to create a rowdy, ride-it-your-way machine that climbs like a goat and descends like a beast. Whether you're railing berms, hitting booters, or threading sketchy tech, this bike punches well above its weight—and doesn’t punch your wallet.

With a Series 3 aluminum frame, RockShox FS35 fork with 140mm travel, and Shimano Deore 1x11 drivetrain, the San Quentin 2 is built for aggressive trail riding, park laps, and urban shredding alike. Add in Tektro 4-piston hydraulic brakes, a TranzX dropper post, and burly Vee Tire Flow Snap 2.6” rubber, and you’ve got a hardtail that’s seriously ready to get loose.
