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.

TECHNOLOGY



UNIDIRECTIONAL CARBON FIBER FRAME

  • Unidirectional carbon fiber construction
  • Internal cable and hose routing
  • Threaded bottom bracket shell
  • Tapered headtube
  • Replaceable downtube bashguard



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.


MODERN GEO FOR THE MODERN TRAIL SLAYER

Using the most from modern features, Rift Zone 29 models utilize short fork offsets and slack head tube angles to ensure that the bike handles perfectly from a seated or standing position, and travels effortlessly up and down the mountain.



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

2023 Rift Zone Alloy 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.




REAR SHOCK SET UP

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.


FRONT 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.
