The all-new 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.
