  • Wheel Size: Mixed 29"/27.5"
  • Frame: Aluminum
  • Size Range: S, M, L, XL

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.

While the Alpine Trail 1 is the starting point in the three-model lineup, we didn’t make any concessions regarding the spec. High-performance Fox suspension keeps you in control, while a Shimano Deore 12-speed drivetrain transmits your power to the wheel. TRP’s Slate Evo 4-piston brakes feature 203mm rotors, keeping all that speed in check in a powerful, fade-free manner.
