  • S.A.V.E. Plus micro-suspension seatstays and chainstays are dramatically shaped to flex and absorb shock and vibration for comfort and control
  • Syntace 142x12 rear thru-axle increases stiffness, strength and durability
  • Braze-on disc caliper mounts use a patent-pending design for low-profile, flat-mount disc brakes; they're ultralight and incredibly strong
  • 650b x 42c wheel/tire combo delivers the full-on speed and snappy handling of a road bike, but with the unreal cornering grip and float of big tires
  • 650 x 42c wheels have nearly the same outside diameter as traditional 700c x 23c road wheels
  • Specs 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.

Why use a 1.5" fork steerer.  I'm assuming I can't change stems as all I see are for a traditional 1 1/8".  I prefer to have more of a rise than what is offered on this bike.
