MULTITRAC 2 LT

MultiTrac 2 LT debuts on the aluminum-framed Alpine Trail alloy models. MultiTrac 2 LT shifts from seatstay pivots to chainstay pivots, ensuring that the suspension performance matches our design goals, which are not achievable using pivots located on the seatstay once travel exceeds 150mm. With MultiTrac 2 LT, the benefits of relocating the rear pivot points from the seatstay to the chainstay become apparent, as it reduces anti-rise, allowing for better chassis control while braking, more mid-stroke support, and better feel at bottom out.

ADJUSTABLE GEOMETRY

With the integrated flip chips, adjustable headset and an aftermarket 29” rear wheel, Alpine Trail aluminum riders can select 12 unique configurations to run their bikes. These configurations allow the best fine-tuning of chassis to trail conditions available. Flip chips are easy to reconfigure trailside and easily done using a 6mm hex wrench, require no additional parts, and incorporate laser-etched graphics that indicate the position of the chips. The stock 27.5” rear wheel can be swapped out for a 29” rear wheel (not included) if desired, along with changing the position of the seatstay flip chips. Furthermore, the flip chips located at the seatstay pivots alter the bottom bracket height and chainstay length (low BB/long CS setting = 345/442mm, high BB/short CS setting = 352/435mm) so that riders can perfectly dial their bike in to match the terrain they are looking to conquer.

Bear Box Downtube Storage

The all-new Alpine Trail aluminum models now feature our Bear Box integrated downtube storage, complete with a custom nylon bag with a weather-sealed zipper. The hatch door is secure and double-sealed, with bottle bosses. Keep your riding essentials safe and protected from the elements during your big ride.

ADJUSTABLE HEADTUBE ANGLE

Using our proprietary headset cups and inserts, the headtube angle on Alpine Trail aluminum models can be adjusted to +0.75° or -0.75° from the standard 63° position, giving the rider three options.

Marin Alpine Trail protection details.

PROTECTION

Chainstay and seatstays are protected with durable rubber guards that minimize noise and protect paint finishes, and integrated downtube guards helps deflect errant rocks, logs, or anything else riders may encounter on the trail.

Additionally, all aluminum frame models include a gasket around the cable exit hole reduces noise and prevents the brake hose and derailleur cable from marring the frame, and a mudflap positioned over the lower suspension pivot keeps spray and muck off the bearings. Cable ports are of an all-new design and keep the frame innards sealed. These ports use rubber membranes punctured during initial assembly and seal around the housing or hose once inserted. They will be available as a service part for when riders make changes to their components.

ONE PIECE ROCKER LINK

Registros

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.

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.

Reseñas

There’s something refreshingly classic about how Marin approached the Alpine Trail Carbon. The choices in travel, spec and geometry might, from a distance, seem a little all over the place, but what results is a bike that can go all over the place. A bike that feels as natural on mellow local lunch loops as it does on big endless descents. The sum of its parts is a versatile machine that has something for most of us ‘normal’ riders, but with just enough extra for the superhuman shredders.

Marin’s Alpine Trail Carbon comes with everything you want, right out of the box. It’s rough and ready to rumble, with high-level components at a price that can’t be beat.

The Marin Alpine Trail is an exceptionally good value for the money, and one of the most playful, fun Enduro bikes that we’ve been on recently. If you’re someone who’s more inclined to approach the trail like a playground and look for side hits and things to pop off, but also want a bike that’s up for some steeper, gnarlier trails, maybe some bike park laps, and a whole bunch of airtime, it’s great.
