The SystemSix makes every rider faster. You can call it free speed, or aerodynamic advantage. We call it the culmination of a systemwide approach to speed, efficiency and real-world performance. Speed yourself up with the fastest UCIlegal road bike in the world.


    SystemSix produces the least aerodynamic drag of any road bike on the market. Since the bike represents about 30% of a rider’s total drag, that translates into less effort for any rider, at any speed.
    The SystemSix’s aero advantage make it faster than lightweight climbing bikes on any climb up to a 6% gradient or more, depending on rider’s power to weight. To put that in perspective, the most revered HC climbs in the Tour only average 7-8%.
    Dropping down a 5% grade, a rider on a traditional lightweight bike would need to put out over 300 watts just to keep up with a rider spinning at a recovery effort on a SystemSix.
    At 48km/h (30mph), SystemSix saves you over 50 watts - huge savings considering an average Cat 1 racer’s Functional Threshold Power is around 350 watts. And even when drafting, you’re still getting up to 60% of that benefit.
    In a 200m sprint with riders putting out a 1000 watt effort, the SystemSix rider would be four bike lengths ahead at the line.
    Even at a mellow group ride pace, SystemSix requires about 10% less power to maintain speed, leaving you with more in the tank when it’s time to throw down.

  • Full System Integrated Design
    The frame, fork, seatpost, bar, stem and wheels were designed together as a holistic system to minimize drag, enhance comfort and optimize stiffness.
  • Tailored 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. Downtube and seat tube shapes minimize the aero effect of bottles, because that’s how we ride.
  • Disc Only
    Disc specific design allowed for aerodynamic optimization of the frame and fork and a wheel/tire choice that would not have been possible with rim brakes.
  • Hidden Cable Routing
    Unique design routes brake lines and Di2 cables through an opening in the front of the headtube, bypassing headset bearings. An integrated steering stop prevents damage to the cables and permits a full +/- 50 degrees of steering rotation (regular riding rarely sees more than 35 degrees of movement).
  • 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. 8 degrees of pitch adjustment. Narrow bar width with flared drops brings your arms closer together when on the hoods for lower drag. Removable cable cover for easy set-up.
  • Gated Spacers
    For faster, easier wheel changes, the Frame and Fork use the Speed Release thru-axle standard. Compatible with any standard thru-axle wheelset.
  • HollowGram KNØT 64 Carbon Wheels
    KNØT 64 combines optimal aerodynamics with all the benefits of big tires. 
    »» 64mm rim depth provides an ideal balance between aerodynamics, weight, and stability in crosswinds. 
    »» 21mm inner rim width increases the effective tire volume: 23c tires yield a measured width over 26mm (25c tires over 28mm), offering potential for lower inflation pressures, greater comfort and better grip. 
    »» 32mm outer rim width reduces drag by helping airflow off a 26+mm tire to reattach more smoothly to the rim. 
    »» Optimized for a 23c tire, but gives riders the option to go bigger without significant aerodynamic penalty.
  • Speed Release Thru-Axles
    For faster, easier wheel changes, the Frame and Fork use the Speed Release thru-axle standard. Compatible with any standard thru-axle wheelset.
  • Power2Max Power Meters
    Light, accurate and reliable Power2Max spiderbased power meters are included on most models. Turn it on with a one-time activation fee and start getting faster. It’s power made easy.
