2021 Cannondale SystemSix Hi-MOD Dura-Ace Di2 Disc Road Bike

2021 CANNONDALE SYSTEMSIX HI-MOD DURA-ACE DI2 DISC ROAD BIKE

Merging an aerodynamically chiselled design with state of the art composites and range-topping components, the Cannondale SystemSix HiMod Dura-Ace Di2 Disc Road Bike is the perfect partner for when attacking any furiously paced race or group ride.

The frameset's design has been meticulously tuned via the wind tunnel and real-world riding scenarios and this partners the high modulus carbon construction to deliver incredibly low drag, sharp levels of responsiveness and sublime levels of comfort. The frameset is complemented by the aero seatpost, handlebar and stem to result in a performance that is the quickest choice for any rider when thundering across valleys, sprinting for the line or for when climbing gradients of up to 6%. The completely internal cable routing donates a crisp aesthetic and also lowers drag further while clearance for up to 30mm wide tyres grants the prospect of the extra compliance and traction bestowed by wider rubber.

Collaborating seamlessly with the frameset is the HollowGram 64 KNOT wheelset and its aerodynamically refined, 64mm deep, full carbon rims. These rims slice through the air, but their wide, bulbous profile works to calm turbulent air and increase control no matter the wind yaw angle. These rims also sport a broad internal width to infuse lower tyre rolling resistance and greater rough road resilience.

Electronically actuated, the top-of-the-range Shimano Dura-Ace Di2 configuration precisely flicks through the vast range of gears to facilitate passage across any route. The hydraulic disc brakes, also Dura-Ace, thoroughly complete the build by donating powerful and modulated stopping power, even in the worst of weather conditions.
