Cannondale SystemSix Hi-MOD Ultegra Di2 Disc Road Bike 2019
Reinventing the aero road bike was never going to be a small task, however, defying the odds, Cannondale have successfully produced the fastest, most aerodynamically efficient option on the market to date. Utilising an ultra-stiff, lightweight BallisTec carbon frameset construction, the SystemSix Hi-MOD Ultegra Di2 Disc Road Bike boasts the kind of performance every discerning cyclist dreams of.
While clearly a race-ready machine, Cannondale have made sure their latest offering is comfortable and compliant enough for training purposes too. The disc-specific profile also allows the aerodynamic efficiency to be honed to levels simply unobtainable using caliper brakes, while the wind tunnel proven design offers some impressive statistics out on the road.
Saving a whole 50 watts at 48 km/h when compared to a traditional lightweight climbing bike, the SystemSix is far more than just an aesthetically pleasing option.
This aero-profiled bike excels in the hills too, surpassing most climbing bikes on gradients up to 6%. Descending is equally mind-blowing, boasting a 100-watt advantage over those bikes on a 5% decline.
Holding back and releasing their aero option later than competitors bought Cannondale the time to put countless hours into research and development, out on the road and in the wind tunnel alike. The result is clearly outstanding, with the SystemSix representing the quickest UCI approved bike available.
The 64mm deep HollowGram KNØT64 carbon wheelset complements the framesets aerodynamic aspirations perfectly, while the Cannondale KNØT seatpost, handlebar and stem combination boosts both the aesthetics and performance in equal measure.
Completed with Shimano’s ever-reliable Ultegra Di2 Groupset, the System six provides the slick, instant shifting expected from a bike of this calibre, while the hydraulic disc brakes ensure modulated, sharp stopping power in any conditions.
