Cannondale SystemSix Ultegra Di2 Disc Womens Road Bike 2020
The Cannondale SystemSix Disc Womens Road Bike, complete with the second-tier Shimano Ultegra Di2 groupset is a machine that aims, and succeeds, to deliver speed in every situation. The frame is an aerodynamic masterpiece with every detail engineered to cut through the air and carefully manage airflow around the bike to improve both speed and stability. Truncated airfoil tube shapes in the frame cut drag and this is supported by a KNOT SystemBar that is both comfortable and aerodynamically optimised, with 8 degrees of pitch adjust to help you refine the perfect fit. Keeping the look clean and sleek, the bar pairs seamlessly with the System Stem that routes all cables internally for the cleanest, clutter-free cockpit.
The HollowGram 64 KNOT wheelset works perfectly in sync with the bike as a unit, optimising airflow around the rims and featuring a wider rim that allows tyres to feel bigger, adding comfort. A KNOT carbon seatpost adds comfort and further drag-reducing qualities to the back of the bike. Speed Release thru-axles make wheel changes easy and improve stiffness so that power transfer is crisp.
FEATURES
- Every section of the frame and fork features tailored airfoil profiles
- Frame and fork are equipped with Speed Release thru-axle standards
- The unique chine shape at the base of the headtube redirects air flow coming up the back of the fork leg, channelling it downstream
- Narrow bar width and flared drop brings your arms closer together when on the hoods for reduced drag
- Shimano Ultegra Di2 with 11-30 cassette and 52/36 crankset
- Full carbon HollowGram 64 KNOT wheelset
- Gated spacers allow you to easily adjust the stem’s stack height, without having to disconnect cables
