Marin Alpine Trail XR GX 2025

Marin Alpine Trail XR GX 2025

The Alpine Trail range is our boldest and most capable collection of enduro bikes ever – built on the most advanced and most adjustable frames we have ever created.

The Series 4 aluminium frames with the MultiTrac 2 LT platform combine a mullet setup (29" front wheel, 27.5" rear), 170 mm of travel at the front and 160 mm at the rear, and offer exceptional adjustability. Riders can set the head tube angle, BB height and chainstay length – and if they wish, they can also run a 29" wheel at the rear. The practical "Bear Box" storage compartment in the down tube includes a nylon zip pouch for tools and other essentials. The 34.9 mm diameter seatpost provides higher stiffness and supports the latest dropper posts.

"XR" stands for "Xtra Rad" at Marin, and like previous XR models, we built the new Alpine Trail XR for demanding riders who want top performance but do not want to break the bank. The bike is fitted with high-performance RockShox Ultimate suspension, a SRAM GX Eagle Lunar 12sp drivetrain and powerful four-piston SRAM DB8 brakes – equipment that will help you step up to the next level.

Maxxis tyres, our own CNC-machined stem with a diameter of 35 mm and a tuned Trail Bar for maximum control on the trail are also included.

Technology

MULTITRAC 2 LT

MultiTrac 2 LT debuts on the aluminium-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 150 mm. 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 aluminium riders can select 12 unique configurations to run their bikes. These configurations allow the best fine-tuning of the chassis to trail conditions available. Flip chips are easy to reconfigure trailside, are quickly done with a 6 mm 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 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 = 345/442 mm, high BB/short CS setting = 352/435 mm) 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 aluminium 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 head tube angle on Alpine Trail aluminium models can be adjusted to +0.75° or -0.75° from the standard 63° position, giving the rider three options.

PROTECTION

The chainstays and seatstays are protected with durable rubber guards that minimise noise and protect the paint finish, and the integrated downtube guard helps deflect errant rocks, logs or anything else riders may encounter on the trail.

Additionally, all aluminium frame models include a gasket around the cable exit hole that 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. The cable ports are of an all-new design and keep the frame innards sealed. These ports use rubber membranes punctured during initial assembly that 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

The Alpine Trail Carbon uses 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 the inevitable log/rock/whatever strikes that may occur on a rowdy ride.

CHAINSTAY PROTECTION

The chainstays on Alpine Trail Carbon models feature an aggressive chainstay protector that not only protects your frame from chain slap but also quietens the ride.
