The GT Avalanche 3.0 hardtail mountain bike offers trail-riding fun and performance at a great price, and features a 100mm suspension fork and powerful hydraulic disc brakes.

  • With 100mm of travel and convenient lockout, the SR Suntour XCM-MLO suspension fork helps maintain handling and smooths out rough trails
  • Suntour cranks power 27 gear combinations, which are guided by Shimano shifters and derailleurs for quick, precise shifts
  • Tektro hydraulic disc brakes offer powerful braking, even in wet conditions
  • Maxxis Sphinx tires offer good traction for mixed trail use
  • Replaceable rear derailleur hanger helps extend the usable life of the frame
  • Specs on the GT Avalanche 3.0 hardtail mountain bike are subject to change

All bicycles sold at REI include a free warranty tune-up. New bikes go through a normal break-in period, after which readjustment is important for longevity and performance. Bring your new bike in to your local REI for its free tune-up within 20 hours of use or 6 months from purchase, whichever comes first. Contact your nearest REI bike shop to schedule this important service.
