Marin Alpine Trail XR Full Suspension Mountain Bike 2026 in Silver/Black

Season:2026

Brand:Marin

Code:7375200ALLOY

The Marin Alpine Trail is their big-hitting, big-wheeling, hard charger.

Its built for the roughest and rowdiest around. Whether you're a park rat, enduro racer snake or just love to send it with the big dogs, the Alpine Trail is the perfect beast for the job.

Series 4 aluminium 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.

Key Features & Benefits:

  • Hydraulic Disc Brakes:Accurate and powerful braking capacity to keep you in control in all weather conditions.
  • 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.
  • Frame 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.
