2025 Marin Alpine Trail XR: Even More Unstoppable

The Marin Alpine Trail XR has long been the go-to machine for aggressive riders who desire a capable all-rounder to dominate technical terrain. The 2025 model elevates that reputation, offering an even more capable platform, boasting 170mm of travel up front & 160mm out back, for conquering the most challenging trails.

Marin Alpine Trail XR 29 2025 - Brushed Alloy

This aggressive full suspension mountain bike boasts a game-changing upgrade: a plush 170mm RockShox Ultimate fork. Paired with a nimble 27.5-inch rear wheel and 160mm of rear travel, the Alpine Trail XR's mullet setup delivers the best of both worlds: lightning-quick agility and unstoppable rollover capability.

 

The progressive geometry carves through corners with laser focus, while the high-performance spec is built to take a beating. Whether you're dicing it up on enduro courses or laying waste to bike park lines, the 2025 Alpine Trail XR fuels your adrenaline-packed MTB adventures. It's a no-compromise machine, ready to unleash your wildest riding ambitions.

ALL-NEW MULTITRAC 2 LT ALLOY FRAMES

 

Debuting on the Alpine Trail alloy models, MultiTrac 2 LT shifts from seatstay pivots to chainstay pivots, ensuring that the suspension performance matches Marins 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.

BEAR BOX DOWNTUBE STORAGE

 

The all-new Alpine Trail aluminum models now feature Marins  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 Marins 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.
