Cannondale SystemSix HiMOD Ultegra Di2 Disc Road Bike 2021
The Cannondale SystemSix HiMOD Ultegra Di2 Disc Road Bike unites an aerodynamically advanced design with sophisticated composite materials to result in the fastest possible performance across an impressive sweep of road riding scenarios.
The frameset utilises high-modulus carbon and moulds this into wind tunnel refined tube sections via an intricate lay-up pattern. The outcome of this combination is the lowest possible drag as well as maximum pedalling efficiency and serene levels of comfort. The aerodynamic shapes of the seatpost, stem and handlebars work seamlessly with the frame's air slicing properties to help any rider go faster on the flat and on any climb with an average gradient of up to 6%. Generous frameset-to-tyre clearance offers the chance of using tyres of up to 30mm in width, allowing rougher roads to be tackled with increased comfort and control.
The HollowGram 64 KNOT wheelset has a deep and wide full carbon rim to lower drag significantly. At the same time, its broad, and blunt profile enhances stability in crosswinds by calming the turbulent air caused by high wind yaw angles. Lower rolling resistance is also promoted by this rim thanks to its wide inner width that coerces tyres into a superior cross-sectional profile.
Accurate and smooth, the Shimano Ultegra Di2 gear configuration helps the rider always to select the correct cadence, regardless of course topography. The Ultegra marque also takes care of stopping duties with this hydraulic disc brake set-up bestowing confidence under even the most inclement of weather conditions.
