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!

An area that has undergone dramatic changes in respect of aerodynamics in recent years is the cockpit and the SystemSix is no exception. Keeping things fast up front is the KNØT SystemBar which provides the low drag and sleek look of a one-piece bar and stem, with the customisable adjustability of a two-piece system. The carbon bar features a full 8° of pitch adjust, so you can dial in your perfect position, while the rounded truncated airfoil shape of the flat section not only maintains consistent airflow throughout the pitch range, it’s also way comfier on your hands than other bars with sharp trailing edges.

Completed with Shimano’s ever-reliable Dura Ace 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.

Rise to Speed anywhere. The R-50’s brilliance is its breadth of ability. With supernaturally balanced performance, you’ll find your fast on any road.  The R-50s will reliably deliver performance in a variety of conditions, and they’re also just plain reliable. Strong spokes, DT Swiss hub internals, and hand-built precision mean you can go hard on any ride or in any race, season after season.  High-performance tire technology has evolved, and HollowGram is here for it. Tubeless compatibility, 21mm internal widths, and hooked sidewalls are part of every package. It’s all optimized around modern road tires, for that ideal blend of ride quality, aerodynamic efficiency, and low weight.  It’s one thing to cut through the wind. It’s another thing to master it. D.R.A.F.T. stands for Drag-Reducing Aerodynamic Flow Technology, an approach pioneered over the course of thousands of testing hours by our in-house aerodynamicists and applied to all HollowGram road wheels. We leverage data and testing focused on real-world riding conditions – like headwinds, crosswinds, and variable winds that shift as you ride – not just those that are simulated in a wind tunnel. The result is rim properties that work with the wind, not against it, and wheels that help you go faster, not just look faster. D.R.A.F.T. creates wheels that help you Rise to Speed, no matter the day.


The bike is in fantastic condition overall with a few minor imperfections.  The shifters do have a few grazes on them, we are happy to source and replace these for you :).  The wheels are brand new as are the tyres.  Shifts are crisp all round with sharp braking as expected and bearings are nice an smooth across the bike.
