Marin Rift Zone XR 29 2025 Bike

Feel the Rifty Love! Marin's take on the ultimate do-it-all trail bike, the Marin Rift Zone is made to party, whatever your jam might be. Your ideal partner for everything from all-day epics, to local shred laps to big mountain adventures, the Rifty is Made For Fun.

The Rift Zone 29 brings together trail-taming 29" wheels, 130mm of rear travel, a lightweight aluminum frame and Marin's super-plush MultiTrac suspension platform for endless good times on the trails.

"XR" means Extra Rad over here at Marin, and with that, the Rifty XR gets an extra spicy build. Starting out front, the fork is RockShox's supreme Lyrik Select+ model, now sporting 150mm of travel. Not wanting to leave the rear in the lurch, the Super Deluxe Select+ shock balances out the bouncy bits. SRAM's wide-range 12-speed GX Eagle drivetrain helps get the power to the rear wheel, while SB8 4-piston brakes offer impeccable braking performance.

Technology

Series 3 Aluminium Frame

Rift Zone alloy models feature Series 3 aluminum frames, with detailed forgings, highly manipulated tubes, and full internal cable routing with new braze-in ports, giving the rider a high feature and high-performing upgrade-worthy platform.

Multitrac Suspension Technology

MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. The rocker link provides a progressive leverage ratio for the rear shock for small bump sensitivity and the feeling of a long travel system on large drops and rocks. 130mm rear travel on all Rift Zone models.

Modern Trail Geometry

Trail geometry with 430mm chainstays, low bottom bracket, long top tube, and a slack 65.5° head angle make for a playful yet confidence-inspiring bike.

Internal Routing

Both carbon and alloy frames sport full internal cable routing in the front triangle with Marin’s all-new internal cable routing grommets, providing a clean and rattle free cable set up.

New Chainstay / Seatstay Protectors & UDH On Alloy Models

Rift Zone models have enhanced chainstay and seat stay protectors for a quiet ride, and utilize SRAM's Universal Derailleur Hanger (UDH) to help future-proof the frame as well as allow for T-type drivetrains.

Enchanced Chainstay / Seatstay Protection

Rift Zone models have prominent chainstay and seat stay protectors for a quiet ride that also protects the paint finish.
