  • Massive 42c tires on 650b wheels give you the the same roll-out diameter as 700x23c wheels for proper road bike speed, but with more cornering grip, traction and comfort
  • Short chainstays give the Slate snappy quickness, while a slack head angle and long front-center keep things stable for off-road excursions
  • With the big-volume tires, plush SAVE PLUS (+) rear triangle and Lefty Oliver suspension fork, the Slate is magically smooth over bumps and chatter
  • Despite its burly look, Slate weighs less than a kilo more than comparable road bikes and smoothly carries speed like a traditional road bike
  • 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.
