The Marin San Quentin 1 is the perfect bike for everybody! This bike is for trail riders wanting to also get some extended airtime. The San Quentin 1 is made from aluminum making it reliable and durable!
Looking for your first real mountain bike that rides like a beast but won’t break the bank? The 2025 Marin San Quentin 1 is your ticket to aggressive trail riding, built tough with dirt-jump attitude and trail geometry that shreds uphill and down. It’s one of the most capable hardtails you can get under 1200—and it’s ready to rip.
The San Quentin 1 draws DNA from Marin’s Alcatraz dirt jumper, meaning it’s playful, confident, and absolutely dialed for technical terrain. With a Series 2 aluminum frame, a 130mm Suntour XCM34 Boost fork, and grippy 2.6" tires, this bike is built to take a hit and keep charging.
Simple, reliable tech keeps you on the trail and out of the repair stand. A 1x9 microSHIFT drivetrain gives you all the range you need with none of the fuss. Tektro hydraulic disc brakes bring the power when the descent gets sketchy, and the wide 780mm bar/stem combo keeps things stable and planted.
Internal routing for a dropper post (easy upgrade down the road)
Modern, low-slung geometry with a 64° head angle for confident descending
Available in 27.5” or 29” wheel setups depending on size—pick your style
The San Quentin 1 isn’t trying to be a race bike. It’s trying to be fun. Jump it, thrash it, ride it to the trailhead or around town—this thing is as at home at the bike park as it is on your favorite rooty singletrack. For new riders or anyone getting back into mountain biking, it’s an unbeatable combo of performance, value, and good looks.
