Cannondale SystemSix Carbon Ultegra Di2
Details
A racing bike with the lowest drag ever tested on a UCI-legal ride. More speed with less effort. Simple as that.
Stem spacers open so that you can adjust stem height without needing to pull cables.
Disc specific design allowed for aerodynamic optimization of the frame and fork and a wheel/tire choice that would not have been possible with rim brakes.
Unique design routes brake lines and Di2 cables through an opening in the front of the headtube, bypassing headset bearings. An integrated steering stop prevents damage to the cables and permits a full +/- 50 degrees of steering rotation (regular riding rarely sees more than 35 degrees of movement).
- BallisTec carbon frame and fork
- HollowGram 64 SL KNOT Carbon wheelset
- 11-speed SHimano Ultegra Di2 components
- Cannondale HollowGram SystemBar KNOT carbon handlebar
- Cannondale HollowGram KNOT carbon stem
- HollowGram 60 KNOT carbon seatpost
- Shimano Ultegra hydraulic disc brakes
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Shifting Performance
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Customization
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Dependability
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
