Dirt jump DNA with all-mountain pedigree. The Marin Bikes 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? TranzX dropper post? You got it. FSA cranks, Maxxis rubber and plenty of kick-ass Marin kit? Abso-freakin-lutely.
