2023 Marin San Quentin 3 Medium Lots of Upgrades

We are selling this hardly used San Quentin 3 for a customer on consignment. The San Quentin 3 has been very tough to get since it was released a while back. Now you can get one with tons of upgrades for almost the cost of a new one!

This was the 1st one we sold and the customer immediately modified it and put just under 3K in upgrades! Shaved off just over 3lb off of the bike. Sales are final *no returns*, shipping is $199 insured to lower 48

You can buy online via our website with a variety of CC options (*price not valid with shop pay installments however* contact us for price if doing installments)

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.


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