Marin San Quentin 3 27.5″ Bike 2023
The Aggressive Hardtail
Hardtails aren’t just for riding on fire roads and tame singletrack. They are perfect for getting rowdy and having fun on the descents too. The Marin San Quentin 3 27.5″ Bike is built for aggressive trail riding. It has a Series 3 6061 aluminum frame that uses 140mm of travel on the front. The frame features internal cable routing, a threaded bottom bracket, modern trail geometry, ISCG tabs, and Boost 12x148mm dropouts on the rear.
The 3 version of the Marin San Quentin Bike comes with a Shimano Deore/SLX 12-speed drivetrain. The gearing is perfect for those steep hills and longer adventures out on the singletrack. Shimano BR-MT420 4-piston hydraulic disc brakes provide excellent stopping power so you can descend with confidence. Marin Aluminum Double-Wall tubeless-ready rims are paired with Vee Tire Co. Attack HPL Tires that can be set up tubeless for a smoother ride, better traction, and fewer flats.
