Cannondale Systemsix Ultegra 2020

About the SystemSix Carbon Ultegra

The Cannondale SystemSix was created with one simple goal in mind - to be the fastest and most efficient UCI-legal road bike in the world. Its unique fully integrated design delivers more speed, in more situations, than any other bike on the market today. For race day fast. And every day fast. It's the world's fastest bike.

To say the SystemSix represents a unique approach to aerodynamic optimized bike design would be a bit of an understatement. Cannondale’s holistic approach to speed represents the pinnacle of what a race bike designed from the ground up can really deliver. Ground up? Indeed. The entire SystemSix project began with a quest to design the fastest wheel possible for modern tire volumes. And we built from there, developing the frame, fork, seatpost, bars, stem and wheels together as a complete speed system. Taking full advantage of disc-only optimization. Tailoring frame tube profiles to control airflow at every point. Developing a bar/stem combo that delivers the fast without forgoing the fit. Yielding the most positive wind tunnel data we’ve ever seen. And all within UCI limits. The most important part of the world’s fastest system, the SystemSix frame and fork are the rock upon which speed is built. Every tube shape painstakingly engineered to be as immune to drag as possible. Purposeful asymmetry for instant response to disc brake and pedalling loads. Impeccable handling and classic road race feel thanks to geometry derived from Cannondales gold standard EVO. And of course, scores of refined details designed to speed you up and not let you down.


Key Features

  • BallisTec Carbon Frame is designed to be stiff but light, allowing you to convert more of your power into speed. Cannondale’s innovative SAVE micro-suspension helps to reduce road buzz
  • BallisTec Carbon Fork is lightweight and engineered to flex, reducing shock and vibration
  • Shimano Ultegra 2x11 Speed Drivetrain provides fast, smooth and accurate shifting, with improved durability for long lasting performance
  • Shimano Ultegra Hydraulic Disc Brakes give powerful, controllable and consistent stopping power, with minimal effort, in all conditions
  • Vittoria Rubino Pro Speed, 700 x 26mm Tyres offer excellent rolling ability on the tarmac whilst keeping you planted and in control


Not just for racing

Racing provides some clear examples of the performance benefits of SystemSix compared to a modern race bike over a range of different scenarios. But SystemSix is not just for elite racers and offers serious benefits to riders of all levels. Take a cruising speed of 30 km/h (~18 mph) on a flat road; a comfortable cruising speed for most road cyclists. Compared to a modern road bike with low profile wheels, SystemSix would save that rider approximately 17W just in aerodynamic resistance. This pace equates to a savings of about 10% of your total power. That is not an insignificant amount when you consider a training ride of several hours. And as you ramp this speed up for more spirited riding the savings only increases. At 32 km/h it’s 20W. At 35 km/h it’s 26W.
