REAL SINGLETRACK RIDING

KEEPING UP WITH THE PARENTS

FUN!

The Rift Zone 26 and Rift Zone Jr are for the ambitious kid looking to keep up with the adults and push the boundaries of the local bike park on a ride just as capable as its full size counterpart. Both models utilize the same frame and fork, so a Rift Zone Jr is easily upgradable to 26" wheels and longer cranks as your little ripper grows. 26" wheels and longer cranks not included, but your local Marin dealer can source the parts.

TRAIL GEOMETRY

We put as much attention when designing the Rift Zone 26/Jr as we do the adult bikes, so young riders get to experience modern long/low/slack geometry, enhancing comfort and control when the trail gets steep and/or rough.

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.
