ALL AROUND TRAIL ENJOYMENT
HAVING FUN
The Rift Zone 27.5 is our most playful trail bike, made for the rider that catches a bit of air off of every root in the trail, is always looking for an alternate line, and ends every ride with a smile. This is an all-around suspension bike with trail performance far out stretching the asking price.
Key upgrades from Rift Zone 27.5 2:
The Rift Zone 27.5 has a Series 3 6061 butted and hydroformed aluminum frame with 120mm travel MultiTrac suspension technology and playful 27.5” wheels. 27.5” wheels fit most riders better and create a lightweight and responsive bike, the most playful trail bike in the line.
LEARN MORE
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.
Trail geometry with short chainstays, low bottom bracket, long top tube, and a slack head angle combined with lightweight and responsive 27.5” wheels make for a playful and quick handling bike.
Rift Zone 27.5 models are compatible with internally routed dropper posts, with internal rear derailleur routing for a clean look and snag free ride.
Boost front spacing is paired with a 148x12mm Boost rear thru-axle on the Rift Zone 27.5 3 and Rift Zone 27.5 2 for frame and wheel strength, and future wheel upgrade compatibility.
The Rift Zone 27.5 1 is spec’d with a 141x9mm axle that is upgradable to a Boost 148x12mm standard, allowing for more options if you decide to take your bike to the next level.

Bolt-On Thru-Axle
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.
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.
