Alpine Trail rocker link detail.

ONE PIECE FORGED ROCKER

The heart of the Alpine Trail’s MultiTrac suspension is the forged one-piece rocker link. The strength and stiffness of the rocker keeps the rear of the bike tracking straight, providing smooth suspension operation under the most demanding conditions.

Detail of the tire clearance that the one piece forged rocker link allows for.

BRIDGELESS SEATSTAY

The stiffness of the one-piece rocker link allows for a bridgeless seatstay design, offering zero compromises on stiffness while at the same time allowing for maximum tire clearance and short chainstays.

MODERN ANGLES

The Alpine Trail has a slack 63.5º head tube angle paired with a steep 78º seat tube angle and long reach to provide the best modern trail bike experience. The bike lets you climb better than ever before, while giving you even more confidence when descending.

Suspension Setup

REAR SHOCK SETUP

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: Check shock body to confirm sag percentage. If more than 30%, add air, if less than 30%, bleed air out.

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.
