Like most things Cannondale, the SystemSix is a considered beast.  Cannondale have spent time and considerable resources in order to bring the absolute best aero bike to market. The SystemSix is so called because it unites 6 key elements of bike design in an integrated aero-philosophy: Frame, Wheels, Fork, Seatpost, Handlebar and Stem. Each is optimised to bring aerodynamic advantage beneficial to the complete bike system. The result is a frameset that is the fastest aero platform available today.  

Not just 'by the numbers', but in real world, day-to-day, club-ride terms. Not just in a straight line; not measured purely at Pro performance levels;  but in a host of environments and conditions that the average club cyclist performs at and can therefore benefit from.  Its unique fully integrated design delivers more speed, in more situations, than any other bike on the market today. For race day fast. And everyday fast. It's the world's fastest bike.

This race-bred speed machine is absolutely the lowest-drag, most efficient, all-around fastest UCI-legal road bike on the market today. Not only the fastest in the windtunnel. Not only the fastest for a select few riders in a select few scenarios, but the fastest for anyone interested in going faster, just about everywhere you’d want to go faster. It's free speed and it is the culmination of a multi-year, systemwide approach to efficiency and real world performance. Proving just what can be accomplished when the entire machine - not just the frame and fork - is optimized for fast. Delivering real speed, for real riders.

The Cannondale SystemSix produces the least aerodynamic drag of any road bike on the market. Because of all the resistive forces your power has to overcome to make speed, aerodynamic drag is the biggest hurdle. It is more important in most situations than all the other resistive forces (weight, rolling resistance, bearing friction, etc.) combined. Even in those few scenarios where it’s not THE most important thing, it’s still a very important aspect. So cutting drag translates into more speed, with less effort, in all the places you’d expect and a lot of places you wouldn’t.....

Faster Down: Descending a 5% grade at 60 km/h (37 mph), a rider on a modern lightweight race bike, like a SuperSix EVO, would need to expend over 300 watts to match a rider pedaling at a 200 watt recovery pace on a SystemSix. Meaning SystemSix riders can truly recover while making others suffer.

Faster Up: The SystemSix’s aerodynamic advantage makes it faster than a lightweight climbing bike, such as Cannondale's own gold standard SuperSix EVO, on any climb up to a 6% gradient or more, depending on rider’s power to weight. To put that in perspective, most revered HC climbs in the Tour de France only average 7-8%.

Faster on the Flats: Compared to a modern, lightweight race bike like the SuperSix EVO, at 48 km/h (30 mph), the 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 you’re drafting, you’re still getting up to 60% of that benefit. That’s more than enough to notice.

Faster in the sprint: In a 200m sprint at 60 km/h (37 mph), all other things being equal, the Cannondale SystemSix will beat a modern lightweight race bike to the line by four full bike lengths. In 200m - that's huge!

Completed with Shimano’s ever-reliable Ultegra 12 speed Di2 Groupset, the System six provides the slick, instant shifting expected from a bike of this calibre, while the hydraulic disc brakes ensure modulated, sharp stopping power in any conditions.

The Systemsix rolls on the fastest road wheel out there, the RYOT55! It outperforms its competitors in real world conditions proven in wind tunnel tests. They developed a new rim profile called LAW Tech. LAW is short for ‘Laminar Airflow Wing’ and has been specially developed to deliver better aerodynamics when using wider tires by creating a smooth airflow.  The 21mm internal rim width will result in an effective tire width of 28,2mm when using 25mm tires. The RYOT55 is also build around the new DT Swiss 240 hubs which have an improved EXP ratchet system. The hub internals now offer an even higher precision with fast engagement and increased stiffness combined with a lower weight. This helps to bring the performance of the wheel to an even higher level.


The bike is in immaculate condition overall with 1 minor chip as photoed.  The wheels and groupset is brand new and comes with the manufacturers warranty.
