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.

Air Charts

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.
