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 SETUP
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 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 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.
