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. Shimano 4-piston brakes and 12-speed drivetrain? X-Fusion dropper post? You got it. FSA cranks, Vee Tire rubber and plenty of kick-ass Marin kit? Abso-freakin-lutely.

Key upgrades over the San Quentin 2:

  • Marzocchi Bomber Z2 fork
  • Shimano Deore wide-range 12-speed drivetrain
  • Shimano MT420 4-piston brakes
  • Vee Tire Co Attack HPL tubeless compatible tires
