Cannondale SystemSix Carbon Ultegra Disc Road Bike 2020
The Cannondale SystemSix Carbon Ultegra Disc Road Bike is simply faster everywhere, be that the club chaingang, hard training or road racing. The fully integrated frame is aero-optimised so that it delivers efficiency in all areas of your riding. The disc-only engineering allows for the frame, wheel and tyre to be developed as an optimised system to help the bike slice through the air, that wouldn't otherwise be achievable with rim brakes. For ease of maintenance and to dial in a perfect fit, the gated stem spacers allow for adjustments to stem height without the need to pull or remove the internal cable routing.
Shimano's reliable Ultegra mechanical groupset with hydraulic disc brakes ensures powerful braking and sharp gear shifting. The semi-compact 52-36 chainrings and 11-30 cassette have plenty of range for carrying high speed on the flat without forcing you to grind up the hills.
Features
- Shimano Ultegra mechanical groupset
- Vision SC55 carbon clincher wheelset
