Marin Rift Zone XR – Extra Range Full Suspension Trail 2025

2025 Marin Rift Zone XR – The “Extra Radical” Long-Travel Performance Trail Rig

The Marin Rift Zone XR is the definitive “rowdy” trail bike, specifically built for riders who find themselves pushing the limits of traditional short-travel machines. This flagship alloy trail MTB takes the proven Rift Zone platform and gives it the “XR” treatment—adding more suspension travel up front and a more aggressive component spec for high-speed stability. Through expert-vetted testing, we have identified the XR as a standout in the “quiver-killer” category, providing a 150mm front end that slackens the geometry for technical descents while maintaining its 130mm poppy rear-end feel. The Series 3 Aluminum frame remains the backbone of this build, offering a bombproof chassis that thrives on abuse.

Radical Trail Geometry and MultiTrac Efficiency

The Marin Rift Zone XR utilizes a 29-inch wheel configuration to maintain maximum momentum over rocky, technical terrain. This performance-tuned trail specialist is equipped with a premium suspension package from Marzocchi and RockShox, delivering a “bottomless” feel during big hits while retaining enough support for efficient pedaling. Navigating the mountain bike landscape requires a drivetrain that can shift under pressure; the XR delivers with a SRAM GX Eagle 12-Speed system, offering a massive 520% gear range for steep alpine climbs. The four-piston hydraulic brakes provide the necessary stopping power to keep the bike’s aggressive 65.1-degree head angle under control on the steepest chutes.

• Frame Construction: Series 3 6061 Aluminum, 130mm MultiTrac travel, 148x12mm Boost.
• Front Suspension: Marzocchi Bomber Z1, 150mm travel, Rail Damper, stiff 36mm chassis.
• Rear Shock: RockShox Deluxe Select+ RT, custom tuned for aggressive MultiTrac kinematics.
• Drivetrain: SRAM GX Eagle 1×12-Speed, mechanical precision with 10-52T cassette.
• Braking System: SRAM Code Bronze 4-piston hydraulic disc brakes, 200mm front / 180mm rear.

“The Rift Zone XR is where trail efficiency meets enduro capability. By over-forking the front to 150mm, Marin has created a bike that is incredibly confident in the steep stuff without losing the playful, snappy character that the Rift Zone is famous for. It is, quite simply, the funnest bike in the entire 2025 lineup.” — BikeRadars Radical Trail Crew
