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.
