          Faster. Everywhere.

          The fastest UCI-legal bike in the world. More speed with less effort. Simple as that.

          Where it thrives

          In competition, the open road, up and down hills

          What it's built for

          Speed, efficiency, agility

          Highlights

          • Ultra low drag Hi-MOD BallisTec carbon frameset / Integrated Cannondale App connectivity
          • Ultegra Di2 electronic shifting / HollowGram crank
          • HollowGram 64 KNØT carbon wheelset / KNØT SystemBar

          Faster Everywhere.

          SystemSix outstrips opponents, and not just where you’d expect. It sprints, descends and even climbs most hills faster, conserving watts off the front, in the draft, and in the laughing group.

          SystemSix is a holistically designed, six-part system wholly dedicated to the pure pursuit of speed. It generates the least aerodynamic drag of any road bike on the market, which means more speed, in more situations, for more riders. It’s faster everywhere.

          Technology

          Speed of Six

          SystemSix is based on a six-part system - frame, fork, seatpost, bar, stem and wheels - designed together holistically to minimize drag, enhance comfort and optimize stiffness for maximum speed.

          Cannondale KNØT SystemBar

          Provides the low drag and sleek look of a one-piece system, with the fit and Interchangeability benefits of a two-piece bar and stem.

          HollowGram 64 KNØT Wheels

          One of the fastest wheelsets ever created. Ultra-wide, disc-only design offers incredibly low drag at a wide range of yaw angles, even with larger volume tires.

          HollowGram 60 KNØT Seatpost

          An vital part of the system, the KNØT seatpost is designed specifically to reduce drag in the high speed airflow that is accelerated between the rider’s legs.

          Customized Airfoils

          Every section of the frame, fork and seatpost features it own customized truncated airfoil shape, designed to reduce drag across the effective yaw range.

          Hidden Cable Routing

          Unique design routes brake lines and cables through an opening in the front of the headtube for minimal drag and headache-free serviceability.

          Connected

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

          Speed Release Equipped

          The Speed Release thru-axles allow faster, easier wheel changes and are compatible with most standard thru-axle wheelsets.

          BallisTec Hi-MOD Carbon

          Cannondale's premium high-strength, high-stiffness carbon construction. A sophisticated blend of high-strength and high-stiffness fibers yields a frame that’s extremely light, lively and durable.
