Product Highlights

Cannondale's highest grade of carbon makes the frameset ultralight, responsive and comfortable.

Truncated airfoil tube shapes decrease drag markedly without adding weight or sacrificing stiffness.

Mid-depth carbon rims with a broad, aero-tuned profile make these wheels fast in all conditions.

An electronic gear setup that gives precise and smooth shifts through its 11-speed cassette.
Cannondale SuperSix EVO Hi-MOD Ultegra Di2 Disc Road Bike 2021
Fast, light and composed, the SuperSix EVO Hi-MOD Ultegra Di2 Disc Road Bike by Cannondale bestows a truly multifaceted performance across any road riding terrain thanks to its potent blend of highly developed attributes.
Efficiency and responsiveness are delivered in abundance by the SuperSix EVO frameset but it still manages to be the lightest frame the brand has ever conceived thanks to its advanced, high modulus carbon construction and refined silhouette. The frameset is also remarkably compliant, bestowing comfort across irregular and broken road surfaces and possesses aerodynamically refined tube sections to lower drag within all fast riding scenarios. The geometry elicits a perfect ratio of nimbleness and composure to help the rider navigate all fast-paced and technical situations in a relaxed manner.
Frame and fork clearance for tyres of up to 30mm in width affords extra cushioning and heightened levels of grip for challenging and fatiguing ride conditions while completely hidden gear cable and brake hose routing keeps the aesthetic sharp and professional.
Blending low weight with aerodynamically refined rim profiles, the HollowGram 45 SL KNOT carbon wheelset perfectly matches the frameset's racy character. At the same time, the broad internal rim width and tubeless-ready tyre compatibility combine to lower rolling resistance substantially.
Any topography can be conquered thanks to the wide range of gear ratios provided by the accurate and reliable Shimano Ultegra Di2 electronic set-up. The partnering Ultegra hydraulic disc brake configuration rounds off the bike with its powerful and precise stopping power that works faultlessly in any weather conditions.
