Flow through trails on the Marin Alpine Trail 29er hardtail mountain bike, which serves up great handling and a 100mm RockShox fork to ensure your time in the woods is spent with a smile.

  • Double-butted 6061 aluminum frame features oversize, hydroformed top and down tubes to provide great rigidity while maintaining lightweight responsiveness
  • RockShox XC28 Tk Mg 29 suspension fork, with preload and rebound adjustment and TurnKey lockout, gives you 100mm of travel to meet the demands of your ride
  • Shimano shifters and derailleurs supply responsive, snappy shifts through the 27 gears; Truvativ crankset ensures your power is efficiently driven to the back wheel
  • Tektro Draco hydraulic disc brakes offer outright stopping power and smooth deceleration no matter the condition
  • 29 in. wheels with Alex TD-20 rims, double-sealed hubs and Geax Saguaro tires let you maneuver easily over obstacles, enhancing forward momentum
  • Specs on the Marin Alpine Trail 29er hardtail mountain bike are subject to change

After its initial break-in period you might notice your bicycle performing less responsively than the day you brought it home. Not to worry, this is typical of all new bicycles and simply reflects that cables have stretched or their housings have seated themselves into final position. To keep running at peak performance, all REI bicycles come with a FREE warranty tune-up, which should be accomplished between the first 100-200 miles of riding or after the first two months if you're accumulating miles less quickly. Contact your nearest REI bike shop for details and an appointment for this important service.
