The San Quentin 1 is our bang-for-your-buck hardcore hardtail that looks and rides like a bike twice the price. Because why should fewer dollars in the bank mean fewer good times on the trails?

We've packed in an SR Suntour XCM34 suspension fork, Vee Tire Co tires, Tektro disc brakes and a load of awesome Marin components to create a bike you’ll love to rip, but that won’t shred your budget. And we've given it a bad-ass paint job that'll cut it alongside those big-bucks bikes.
