About the productCannondale SuperSix EVO Carbon Disc Ult Di2 Road Bike 2021

Brief description

Low-drag frameset, electronic shifting, hydraulic brakes, carbon fibre wheels – everything on the new SuperSix EVO Carbon Disc Ultegra Di2 is optimized for speed and performance, making this one of the fastest pure road bikes. It’s an evolution rather than a revolution, but it’s one of the fastest road bikes out there, giving you a comfortable ride and allowing you to push it as hard as your legs can.


Detailed explanation

Whether you want to push hard on your training rides, or you’re looking for the next racing machine to get up on the podium, Cannondale’s 2021 SuperSix EVO Carbon Disc Ultegra Di2 is the carbon fibre road bike to make that happen. It’s a versatile bike that embraces a racing geometry and an aero-optimized frame to become one of the fastest bikes out there.

The BallisTec carbon fibre frame comes with airfoil tube shapes that reduce drag by up to 30%, making this a frame that can go as fast as you can push it. And that’s without sacrificing comfort, too – the SAVE micro-suspension technology in the rear triangle absorbs road vibrations to reduce fatigue. Add to this internal cable routing and an integrated crown race, and this is a very clean bike, too.

The components are all Shimano’s electronic Ultegra Di2 groupset, which shifts quickly and consistently regardless of how hard you’re pushing things. The HollowGram crankset is stiff and durable, and you also get hydraulic disc brakes with 160mm rotors at the front and rear.  

Factor in the carbon fibre wheels and low-resistance tyres, and the 2021 Cannondale SuperSix EVO Carbon Disc Ultegra Di2 will quickly become your favourite bike.


Technical features

  • BallisTec carbon fibre frame and fork with aero-optimized tubing and race-ready geometry.
  • Shimano Ultegra Di2 electronic groupset makes shifting a breeze, with a consistent and reliable shifting performance.
  • Carbon fibre HollowGram 45 KNOT wheels are tubeless-ready and keep weight low.
  • Cannondale Wheel Sensor sends accurate readings for speed and distance to your smartphone.

Previous model reviewed. I live in a very hilly town and the difference between this and the Specialized e-gravel bike is huge.
