Our store offers custom orders for all bikes to ensure you get exactly what you want. While we list items as 'In Stock,' they may need to be ordered from our distributor. We strive to keep inventory accurate, but feel free to call us for real-time checks or direct transactions. Additionally, we carry an extensive demo fleet for sizing and try-before-you-buy options.

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.
