Product Description


Cannondale refers to the SystemSix as the fastest and most efficient UCI-legal road bike in the world. For racers, this aerodynamic and lightweight road bike is a perfect weapon. A fully integrated design delivers more speed in more situations including massive sprinting power, excellent climbing, and efficient descending. The combination of this frame’s aerodynamic advantage along with its lightweight carbon layup makes it faster than traditional road climbing bikes on gradients of 6 percent and higher. On a descent of 5 percent, the Cannondale SystemSix requires 300 fewer watts to hit the same speed as a standard road bike.

The Frame of this version of the Cannondale Synapse is made with their BallisTec Carbon with intermediate modulus fibers. This material is less expensive than the Hi-Mod fiber but is still plenty light enough to conquer climbs with ease while holding a similar level of stiffness and deflection as its more expensive counterpart. This frame is designed for tight control with a great balance of light weight and ride feel. Anyone looking to save a bit of money without a hit to performance should consider the Synapse Carbon frame as their base.

Aerodynamics are a huge perk of the SystemSix. This bike is designed to go faster with less effort and Cannondale claims that it has the “least aero drag of any road on the market.” A rider’s bike represents 30 percent of their overall drag. Having a bike as aero as this one translates directly into less effort for faster sprints. A Cannondale System will finish a 200m sprint approximately four bike lengths ahead of a standard road bike at 100 watts. On a flat, this bike will require 50 watts of power less at 30 miles per hour. The aerodynamic advantages of the Cannondale SystemSix HM make it a worthy weapon in any race.

The geometry of this bike puts you in a natural racing position, making those aero advantages even greater with minimal effort. A flat back leads to flat out speed as well as a responsive and nimble ride regardless of handlebar position. Cannondale’s Systembar is a one-piece system with low drag thanks to a narrow bar width and flared drops with 8 degrees of pitch adjustment, contributing to the aero nature. The frame, fork, seatpost, bar, and stem are all integrated together to form a specific system to minimize drag. This integration enhances comfort and optimizes stiffness to give you all-around performance.

The SystemSix Dura-Ace is equipped with reliable disc brakes for safe and modulated stopping power in all weather conditions. This is great for heat dissipation as you bomb fast descents. It also features a mechanical Shimano Dura-Ace groupset for some of the smoothest and easy to maintain shifting on the market. Internal cable routing will eliminate the chance of cables getting in your way or becoming damaged due to the elements. Anyone looking for pure speed on the road will find what they need in a Cannondale SystemSix Dura-Ace.
