The Alpine Trail series is our boldest and most capable line of enduro bikes ever, built upon our most advanced, most adjustable frames to date.
Series 4 aluminum MultiTrac 2 LT frames feature mixed 29”/27.5” wheels, 170mm front and 160mm rear travel, and the utmost in adjustability. Riders can alter the head tube angle and bottom bracket/chainstay length, as well as run 29” rear wheels if desired. “Bear Box” downtube storage includes a zippered nylon bag to house trail essentials, and a 34.9mm seatpost increases strength and is compatible with the latest dropper posts.
"XR" = "Xtra Rad" here at Marin, and like the XR models that have preceded the new Alpine Trail, we created a model for the more discriminating rider. We focused our efforts on building a bike with high performance RockShox Ultimate-level suspension, a SRAM GX Eagle Lunar 12-speed drivetrain and DB8 4-piston brakes - all equipment that helps the rider level up, but without blowing the budget. Don't forget the Maxxis rubber and our proprietary CNC machined 35mm stem and matching Trail Bar.

Technology
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.
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.
29" F&R WHEELS
The Alpine Trail Carbon was built upon a 2 x 29" wheel setup, for the utmost in climbing efficiency and ability to roll over whatever lays before you on the trail.
UNIDIRECTIONAL CARBON FIBER FRAME
Alpine Trail Carbon 1 and 2 models feature high modulus carbon fiber and monocoque construction to deliver the strongest and stiffest Alpine Trail to date.
ONE PIECE ROCKER LINK
The Alpine Trail Carbon utilizes a stout one piece rocker link for maximum frame rigidity and suspension performance, while also allowing for bridgeless seatstays for enhanced clearance.
DOWNTUBE PROTECTION
Alpine Trail Carbon models have an integrated and replaceable downtube protector to fend off inevitable log/rock/whatever strikes that may occur when out on a rowdy ride.
MODERN GEOMETRY
Alpine Trail Carbon models are designed with 63.5° headtube and 78° seattube angles that make the bike well-suited to both the descents as well as the climbs.
CHAINSTAY PROTECTION
The chainstays on Alpine Trail Carbon models feature an aggressive chainstay protector that not only protect your frame from chain slap, but also quiet the ride.
Suspension Setup
REAR SHOCK SETUP
Recommended Sag = 30%/19.5mm
Step 1: Use your finger to slide the rubber bump stop (on the shock shaft) up to the seal head.
Step 2: Sit on the bike and put all of your weight on the bike. Do *not* cycle the suspension.
Step 3: Measure sag (from shock body to bumper), If it does not match the bike’s recommended sag in millimeters repeat process, and replace coil spring with appropriate rate.
Step 4: 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 manufacturer.
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
Marin has a winner on their hands with the Alpine Trail. This bike is a great blueprint for a full-value, but affordable gravity-focused ride. I’d happily ride the Alpine Trail as my one bike, as long as I lived somewhere with descents to justify it. The value is there, the adjustability is there, and most importantly, so is the performance.
I had a wonderful time riding this bike for a couple of weeks at the Mount Bachelor Bike Park. If you're in the market for an ultra-versatile, hardcore freeride machine, then I think you can look no further than the Marin Alpine Trail XR.
