Downhill Trails

  • Light Dirt Jump
  • Enduro

The San Quentin 3 is the top dog in the SQ family. We’ve worked tirelessly to create the very best-specced San Quentin ever but still kept the price tag down to earth and in reach of everyone. Marzocchi Z2 fork? Check. TRP 4-piston brakes and 12-speed drivetrain? X-Fusion dropper post? You got it. FSA cranks, Maxxis rubber and plenty of kick-ass Marin kit? Abso-freakin-lutely.

Key Upgrades From The San Quentin 2

  • Marzocchi Bomber Z2 fork/li>
  • Shimano Deore wide-range 12-speed drivetrain/li>
  • TRP Slate Evo 4-piston brakes/li>
  • Maxxis Assegai tubeless compatible tires/li>

Technology

Series 3 And 2 Aluminum Frames

The San Quentin 1 features a Series 2 aluminum frame, with tapered head tubes, 3D forged drop outs, IS brake mounts, and semi-internal cable routing. The San Quentin 2 and 3 feature Series 3 aluminum frames, with more advanced tube forming, more complex dropouts, post mount disc tabs, full internal cable routing, and a boost 148mm thru-axle

Dirt Jump Inspired Frame Style

Taking cues from the Alcatraz, the San Quentin line up provides all the benefits of the DJ style with massive stand over, slick frame tubes, and a sexy paint job.

Modern Trail Geometry

The slack head tube angle paired with a steep seat tube angle create a ride that will fly uphill with perfect front wheel precision but then descend like it’s on rails. The balanced rider position thanks to the steep seat tube puts your weight between the wheels for impressive climbing and handling on flats, while the slack front end and short rear center help to pull you through the rough descents and corners with an intuitive feel.

ISCG Tabs

San Quentin 2 and 3 models feature ISCG 05 tabs for easy chain retention device installation for rowdier riders.
