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.

Key upgrades from Rift Zone 29 1:

  • RockShox Deluxe Select R Debonair rear shock
  • Shimano Deore 12-speed drivetrain
  • Vee Tire Flow Snap 2.35" tires

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.

Reviews

Really, the Marin Rift Zone 2 has it where it counts. It behaves like I want a bike like this to behave. In pretty much every metric, it fixes what was wrong with short-travel bikes of old. The suspension is supportive enough to ride where I would normally want longer travel. The frame is stiff enough that I could boss it around without feeling like I was going to break it. And the geometry was forgiving enough that it could keep up with someone who’s been riding for almost 28 years. But that’s not the point. When building this bike, Marin prioritized the things that are the most likely to get a new rider hooked. It may be the best gateway drug on the market. First trip is just $2,050, kid.

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.
