FAST PACED, EPIC RIDES

PUSHING THE ENVELOPE UP AND DOWN THE TRAIL

CHASING PERSONAL RECORDS

The Rift Zone is our most speed oriented MultiTrac bike, created for the rider looking for the speed and roll over capabilities of 29” wheels in a trail capable package. Long, low, and slack trail geometry is more aggressive than an XC race bike for more control at top speed, and more fun while chasing seconds.

Suspension Setup

REAR SHOCK SET UP

Recommended Sag = 30%/15mm

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 SET UP

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 manufacture.

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.

Reviews

Marin absolutely nailed it with this bike. Not just the fit and finish, but the characteristics of this bike make it a great all-rounder. Something you can take on 90% of the trails and have and absolute blast, and it's one of the best values you're going to get.

The Rift Zone has long, low, and slack geometry. This makes the bike much more aggressive than a cross-country race bike while providing more stability at high speeds and more smiles through technical terrain.
