Cannondale SystemSix Carbon Ultegra Di2 Disc Road Bike 2020
Cannondale's SystemSix Carbon Ultegra Di2 Disc Road Bike utilises technology and innovation at its most advanced. The BallisTec carbon frame and fork are engineered for the ultimate in drag reduction, with tailored airfoil profiles to control the flow of air. Wind tunnel development and testing results show this to be the fastest bike currently out there, within UCI limits. Even on climbs of gradients over 6%, this bike can outperform a lightweight climbing bike. The disc brake specific design plays a large part in the performance credentials, being able to take the design far beyond the limitations of caliper brakes.
Shimano's Ultegra Di2 groupset performs exceptionally well, with shifts being smooth and fast at just the light touch of a button. Disc braking is powerful and reliable no matter the conditions, inspiring confidence and bringing additional control at high speeds and on technical roads. One of the fastest wheelsets out there, the HollowGram KNOT 64s are the perfect complement for a frameset of this calibre. They've been optimised for 26c tyres for speed with no compromise on comfort.
Cannondale's KNOT bar and stem reduce drag and make the aesthetics incredibly sleek yet still offer plenty of adjustability so you can dial in the perfect position.
