The Shimano Deore 12-speed drivetrain delivers smooth, crisp shifting with a wide 10-51T cassette, letting you climb efficiently and spin up for fast descents. Shimano MT420 4-piston hydraulic disc brakes offer reliable stopping power with excellent modulation, backed up by large 203mm and 180mm rotors for confidence on steep trails.

Rolling on 27.5” wheels with wide Maxxis Assegai 2.5” tyres, the San Quentin 3 grips across a variety of terrain, while the tubeless-ready rims allow for lower pressures to boost traction and comfort. The X-Fusion Manic dropper post with size-specific travel allows easy saddle adjustment on the fly, keeping you perfectly positioned as the trail changes.

The Marin San Quentin 3 27.5" brings together reliable components, aggressive geometry, and trail-tough design to handle everything from technical singletrack to bike park sessions.

Occasionally, without notice, manufacturers change product design and/or specifications.
