          Features

          Engineered Simplicity

          Low-friction bushings on the Kingpin thru-axle offer smooth action, maintenance-free reliability and over 100 grams of weight savings vs conventional cartridge bearings.

          Clearance and Compatibility

          The new dropped chainstay design lets you run big volume tires (up to 700x45mm or 27.5x2.1", with 6mm of mud-shedding clearance on each side), all with a standard dish rear wheel for easy interchangeability.

          Tuned for the Rider

          Our Proportional Response size-specific construction creates optimal frame stiffness and compliance for each frame size, so that every rider has the ideal ride feel and comfort of Kingpin.

          SmartSense Ready

          Make every ride better with enhanced visibility and awareness. The SmartSense-ready frame means it's easy to upgrade to our system of intelligent running lights and rear-facing radar.

          OutFront Steering Geometry

          Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in the rough stuff.

          Connected

          An integrated wheel sensor delivers hyper-accurate speed, route and distance info while you ride, registers your bike, reminds you of needed service and more, all through the free Cannondale App.

          Dropper Ready

          Built to accept an internally-routed 27.2mm dropper seatpost, which shouldn't really be a surprise on a bike this off-road capable.

          Load Up. Roll Out.
          With plentiful gear and waterbottle mounts on the frame and fork, Topstone Carbon is ready to load up and go long.
          Corner like a Boss
          Rail through the rough and come out smiling. Led by our OutFront steering geometry, the Topstone Carbon offers up handling that's serenely stable in the chop, and light & nimble everywhere else.
