Cannondale SuperSix EVO Ultegra Disc Road Bike 2023
The ultimate all-round performance road bike, the Cannondale SuperSix EVO Ultegra Disc excels across a range of ride types - in the mountains, in road races and on long weekend club runs alike. It's constructed from Ballistec carbon, with a layup that balances low weight and responsiveness with strength and compliance. The tubing is shaped for enhanced aerodynamics without compromising on weight or integrity. Cannondale has incorporated their race geometry for sharp handling, and the frame has clearance for 30mm tyres, bringing improved comfort over the roughest road surfaces.
Shimano Ultegra components are reliable and precise, for smooth, fast shifting across the wide range of gears. The hydraulic disc brakes inspire confidence at speed in all conditions, ensuring equal stopping power whether the roads are dry or wet. HollowGram 35 wheels have carbon rims and are robust yet light, and their tubeless-ready construction enables a further reduction in rolling resistance. All cables are routed internally through the HollowGram KNØT stem and the frame for clean aesthetics and a further drag-reducing advantage.
