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.

by fromLove this beautiul mountain bike First mountain bike! I bought new pedals and hand grips -- the factory ones just weren't cutting it. Immediately following the purchase and store tune up, I went for a 15-mile ride. Awesome! 29ers aren't an option with this one but who cares? I could take curbs head on, no problem!
