Feel the Rifty Love! Our 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 our 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.

Suspension Setup

REAR SHOCK SETUP

Recommended Sag = 30%/19.5mm

Step 1: Set correct pressure in rear shock.

Step 2: Sit on the bike and cycle the suspension (*with correct riding gear).

Step 3: Reset O-ring and sit on the bike, DO NOT BOUNCE, carefully step off.

Step 4: Measure sag (from o-ring to seal of shock), If it does not match the bike’s recommended sag in millimeters repeat process.

Step 5: Adjust rebound setting to ensure proper control.

FORK SETUP

Marin recommends that all bikes front and rear suspension feel balanced

Step 1: After rear sag is set follow the recommended pressure from the fork manufacturer.

Step 2: Bounce evenly up and down on the bike, cycling the suspension up and down to make sure both front and rear suspension feel balanced, if the front does not match the rear add or release pressure.

Step 3: Once the bike feels balanced adjust the rebound damping to ensure proper control.
