Cannondale SystemSix Hi-mod Ultegra Di2, model 2021

Aero road bike, top carbon frame, Shimano Ultegra 2x11 electronic shifting, Hollowgram KNOT 64 carbon wheels, Shimano hydraulic disc brakes.

A road bike is not just a frame with a fork. The system approach, which, in addition to the frame and fork, also takes into account the braided wheels, stem, handlebars and seat post, brings the American brand Cannondale the title of the fastest road bike on the planet. Six key elements working as a single unit in the pursuit of absolute speed and the lowest possible aerodynamic resistance. In demanding descents, grueling climbs, in tense sprints. Anytime and anywhere. The Cannondale SystemSix Carbon Ultegra Di2 is simply the fastest road bike you'll ever ride.

YES, THIS IS REALLY THE FASTEST ROAD BIKE ON THE PLANET
It is not the fastest only in the wind tunnel or for a select few riders in predetermined scenarios. SystemSix is the fastest for everyone. Anytime and anywhere. Call it drag reduction or aerodynamic advantage. We call it Free Speed, which is the culmination of many years of a systems approach to real-world driving efficiency. Proving what can be achieved when the entire bike - not just the frame and fork - is optimized for speed.

SPEED OF THE SIX-PART SYSTEM
The new SystemSix is a true example of the whole being greater than the sum of its parts. Six points that work together as one integrated system. Frame, fork, seat post, handlebars, stem and braided wheels. A holistic approach to minimizing drag that harnesses every single watt of your performance. An aero frame and fork alone can never achieve the results we have achieved. Simply put, the SystemSix delivers more speed in more situations than any other road bike on the market.
Faster on climbs. On all grades up to 6% or more depending on rider weight and performance, the SystemSix is faster than lightweight hill bikes such as the gold standard SuperSix Evo due to its aerodynamic advantage. Just to clarify, most hard climbs on the Tour average 7-8%.
Faster downhill. At a 5% descent and a speed of 60 km/h, a rider on a modern racing bike, such as the aforementioned SuperSix Evo, will need over 300 watts to keep up with a rider on a SystemSix bike. The latter needs a whole 100 watts less to achieve the same speed. This means you can regenerate in peace on the SystemSix bike while your opponents suffer in silence.
Faster on the flat. At a speed of 48 km/h, SystemSix saves you up to 50 watts of power compared to a light racing bike. Given that the functional threshold power of a trained competitor is around 350 watts, these numbers are really extraordinary. Unless you're one of those who watch every watt, trust me that's more than enough to notice.
Faster in a sprint. In a 200m sprint at 60km/h, a SystemSix rider finishes 4 wheel lengths ahead of a lightweight racing machine such as a SuperSix Evo.
Faster every day. Even at a leisurely pace in the group, typically around 30 km/h, the SystemSix needs 10% less expended energy than a lightweight racing bike like the SuperSix Evo. Thanks to this, you will have more strength left for the time when you have to really step into it.

SYSTEM APPROACH
To say that SystemSix represents a unique approach to solving aerodynamic drag would be too simple. Our approach to speed represents the pinnacle of what can be achieved in road bike engineering. The whole SystemSix project started with an effort to design the fastest braided wheels for today's popular wide road tires. From there we continued through the development of the frame, fork, seat post, handlebar and stem so that together they create one single perfect system. Thanks to the disc brakes, we could let our imaginations run wild. We tuned the profiles of the frame tubes so that they have optimal aerodynamic properties in each of their places. We designed a unique combo handlebar and stem with low air resistance without compromising on comfort. Our efforts have borne fruit in the form of the best wind tunnel data we've ever seen. And all this within the rules of the International Cycling Union UCI.

BASICS OF SPEED
The most important part of a SystemSix road bike is its frame together with the fork. The shape of the frame tubes has been designed to remain maximally immune to flowing air. Purposeful asymmetry contributes to the immediate response of pedaling wheels and braking. The finely tuned geometry derived from the SuperSix EVO road machine takes care of balanced steering and a perfect driving feeling. Of course, there are dozens, if not hundreds, of refined details designed to make you even faster.
Aerodynamic profiles. The basis of the frame set are carbon tubes with a refined aero profile. Everything is designed from the beginning to ensure minimal air resistance, preferably in all the main directions of wind action.
Unique shape of the head part. The unique shape of the head tube heel helps direct airflow from the rear of the fork downwards. It thus prevents mixing of currents from the fork with currents arising behind the head tube of the frame.
Smooth fork shape. Freed from the constraints of rim brakes, the crown area of the fork is radically different from traditional road bikes. Its shape is sleek for maximum integration with the frame and to achieve the least possible air resistance. Thanks to this, there was also more space for wide tires and unhindered air flow even at the highest speeds. Asymmetric leg shape for good control when braking.
