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 we pulled out all the stops with the XR AXS take on the Alpine Trail. Not only did we grace the bike with Ultimate-level RockShox suspension, but took the drivetrain up a notch with SRAM's GX Eagle AXS wireless 12-speed drivetrain. SRAM's Code Bronze brakes provide tenacious stopping power with their 4-piston calipers and 203mm rotors.
