Dirt jump DNA with all the speed and roll-over of 29" wheels. The San Quentin 3 29 is the top dog in the SQ 29 family. We’ve worked tirelessly to create the very best-specced San Quentin 29 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.

Reviews

The San Quentin 3 would be an excellent gateway into the sport for the rider that's eager to progress, but also doesn't want to completely drain their savings account on a bike. It'd also make a great second bike for anyone that's looking to mix things up by spending time on a hardtail - it's a great way to sharpen skills that may have been dulled by rear suspension. Overall, the San Quentin's versatility is its biggest strength; the fact that it's not that hardcore of a hardtail is part of what makes it so good.

A value-packed hardtail that can kick the crap out of a lot of full suspension bikes that cost two to three times as much in a lot of different areas...
