  • A full-tilt road bike with legitimate off-road chops, Slate is the bike for cyclists that want to ride roads without having to "road ride"
  • 650b road wheels with big 42c tires offer the same rollout (outer diameter) as a 700 x 22 wheel / tire combo, yielding the grip and float of big tires plus speed and handling
  • 6069 alloy frame is lightweight, stiff and responsive; agile geometry with short chainstays and slack head angle provide stability for rough roads and off-road excursions
  • Lefty Oliver carbon fork with Push-Button Rebound (PBR) offers 30mm of responsive travel and precise handling; easy-access lockout and rebound controls are glove-friendly
  • Dramatic shaping of seatstays and chainstays provides balance of smoothing capability and solid rigidity for riding on mixed terrain
  • Compact crankset is paired with 11-32 tooth rear cassette for 22 capable gears for climbing, descending and anything in between
  • Shimano Ultegra shifters and derailleurs move swiftly and oh-so-smoothly through the gears
  • Shimano BR785 hydraulic disc brakes provide smooth, powerful deceleration even in wet, slick conditions
  • Pedals not included
  • 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.

Looking for a Hybrid bike - Cannondale Website recommends this for me but looks like mens.... is this ok unisex? And what size chart do I use to determine size - Mens/Womens? I am 5'-5.5" tall and inseam 29/30. What size do you recommend if ok for women. 

Asked by: Jen9
I have a Slate Ultegra, am male, 5'7" with a 29 inseam, and the Small fits me perfectly. This bike has a compact frame and a high standover compared to other bicycles I own. You should do OK with a small, but I suggest you definitely ride it first, to see if it works for you. I believe that Cannondale came out with a women specific version of the Slate this year, maybe check that out too.
