Cannondale SuperSix EVO Ultegra Di2 Disc Road Bike 2021
Merging a full carbon frameset that boasts a gamut of sophisticated design traits with high-grade components and a balanced geometry, the SuperSix EVO Ultegra Di2 Disc Road Bike from Cannondale is a truly versatile performer. Excelling up the steepest climbs, over the roughest roads and everything in-between, the SystemSix EVO delivers whatever the challenge.
The frameset naturally boasts the perfect blend of low weight, stiffness and comfort thanks to the refined lay-up pattern of its BallisTec carbon construction. Each tube section is sculpted into a truncated airfoil cross-section that reduces drag markedly without affecting strength or adding any weight. Realised in a racy geometry, the ride is reactive and sharp but at the same time composed to grant a truly composed ride. Clearance for up to 30mm tyres affords the option of serene levels of comfort while full internal gear cable and brake hose routing promote a crisp aesthetic.
A HollowGram 45 SL KNOT wheelset sports full carbon rims that are light and nimble and boast aerodynamically chiselled profiles to lower drag and heighten control when the wind is blowing hard. The broad internal width of these rims and their tubeless-ready tyre compatibility combine to reduce rolling resistance markedly.
Any topography can be conquered thanks to the wide range of gears provided by the precise, electronic Shimano Ultegra Di2 configuration. The reliability and accuracy of these gears are matched by the partnering Ultegra hydraulic disc brake set-up that affords powerful and modulated braking in all weather conditions.
