Built with dirt-jump DNA and all-mountain capability, the Marin San Quentin 3 2026 is the flagship of the San Quentin range. Designed for riders who want an aggressive, playful and capable hardtail, the San Quentin 3 combines a modern Series 3 aluminium frame with a serious component package that is ready for everything from technical UK singletrack and bike-park laps to jumps, drops and everyday trail riding.
Finished in the eye-catching Purple Fade, this is a hardtail that looks as good as it rides. Marin has packed the San Quentin 3 with high-quality components while keeping it at a competitive price, making it an excellent choice for riders looking for a high-performance hardtail mountain bike without moving into full-suspension territory.
At the front, a Marzocchi Bomber Z2 fork delivers 140mm of travel with Boost spacing and a Kabolt axle, giving the bike the control and confidence needed when the trails get rough. The aggressive trail-ready setup is completed by Maxxis Assegai 29 x 2.5 tyres with EXO casing and MAXX TERRA compound, mounted to tubeless-compatible Marin double-wall aluminium rims.
Stopping power comes courtesy of TRP Slate EVO four-piston hydraulic disc brakes, with a large 203mm rotor at the front and 180mm at the rear. Whether you're tackling steep descents or pushing your limits on technical trails, the San Quentin 3 has the braking performance to match.
The Shimano Deore 12-speed drivetrain provides a huge 1-51T range, giving you the gearing needed for steep climbs while retaining plenty of speed for flowing sections and descents. An FSA Comet 32T crankset with MegaTooth technology provides a durable and dependable foundation for hard trail riding.
A TranzX dropper seatpost with handlebar-mounted remote makes changing your riding position quick and easy. Travel varies by frame size, with 125mm on Small, 150mm on Medium and 170mm on Large and XL models.
The San Quentin 3 also features modern trail-ready standards including Boost 110/148mm hub spacing, a 12x148mm rear thru-axle, internal cable routing and a threaded 73mm bottom bracket. The Series 3 6061 aluminium frame is double-butted to provide a strong yet practical platform for aggressive riding.
Whether you're looking for a Marin hardtail mountain bike in Liverpool, a playful trail bike for the weekend or a versatile hardtail capable of handling jumps and technical terrain, the Marin San Quentin 3 2026 is built to deliver.
