Show Description

Mix up your riding regimen. From silky pavement to gravel roads, this ride revels in all of it. With a gorgeous Ultegra groupset, it's efficient and smooth on the climb, but nimble and punchy in the dirt. The frame features the Kingpin suspension system, for a buttery back-road experience. Weird but wonderful, this is the bike for experimental commuters, gravel racers and dirt-loving roadies.

  • BallisTec Carbon frame and carbon fork, with efficient gravel bike geometry.
  • Kingpin suspension for 30mm of vertical compliance, without lateral compliance.
  • 2x11 drive train pairs 46-30T chain rings with an 11-34T cassette.
  • Shimano Ultegra groupset.
  • Hydraulic disc brakes with 160mm rotors.
  • Shimano HyperGlide 11-speed chain.
  • Double-wall alloy rims (tubeless ready).
  • 700x37c tires.
  • Wheel sensor pairs with your phone via the free Cannondale app and uses Garmin™ technology to record your rides, provide your: time, speed, distance, calories, etc. and it even tells you about your carbon offset. The app also provides reminders for needed services, tracks service history and more.
  • Wheel sensor works with ANT+® or Bluetooth® and uses an easily replaceable 2032 battery that lasts more than a year.
