Description
Blending a sophisticated carbon composition with a wind-cheating profile and a smattering of high-end components, the Cannondale SystemSix Ultegra Road Bike is the quickest choice for any cyclist across a multitude of road riding applications.
A full BallisTec carbon frameset is realised with aerodynamically refined tube shapes to grant power transmission, comfort and stunningly low drag. When combining this frameset with the aero seat post, handlebars and stem the SystemSix becomes the fastest option across flat valleys, within sprints, down descents and even on climbs of up to 6% in gradient. Generous frame-to-tyre clearance accepts tyres widths of up to 30mm while a racy geometry offers a perfect balance of nimbleness and composure.
The Vision SC55 wheelset complements the technically advanced frameset perfectly thanks to it’s lightweight, stiff and aerodynamic carbon rim that is also tubeless-ready tyre compatible. Gear changing duties are charged to the ever-reliable and precise Shimano Ultegra setup that flicks through its ratios with ease. The hydraulic disc brake configuration, also from the Shimano Ultegra range, completes the bike via its powerful and assured stopping power that affords confidence across all riding conditions, even torrential rain.
