Cannondale SystemSix Hi-Mod Dura Ace Di2 Disc Road Bike 2020
The Cannondale SystemSix Hi-Mod Dura-Ace Di2 Disc Road Bike is a low drag, sleek speed weapon. All elements of the bike work together as a system to reduce drag and promote fast riding. The frame and fork feature airfoil tube profiles that cut through the wind and improve the flow of air around the bike across the critical yaw angles, enhancing stability as well.
At the front is the innovative KNOT SystemBar that features an 8° pitch adjust for optimal customisation and an ideal fit to maximise your efficiency, and this marries perfectly with the SystemStem that routes Di2 and brake cables all internally for the cleanest cockpit. Even the gated spacers allow you to adjust the stack height with minimal fuss and with no need to disconnect cables.
Rolling on HollowGram 64 KNOT wheels, that were designed specifically as part of the SystemSix project, the rims are wider than standard so that tyres feel bigger and plusher to both enhance comfort on the road as well as handling. More importantly, though it helps the tyre to integrate seamlessly with the rim for the cleanest control of air around the wheels.
As you would expect, the bike is dressed with the top line Shimano Dura-Ace Di2 electronic groupset so that your gear shifting is on-point in every situation, and you never miss a beat or an opportunity to drop more power, and a Power2Max spider-based power meter lets you delve further into your ride stats.
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
- Power2Max spider-based power meter included, which is light, accurate, reliable (requires a one-time fee to activate)
- Narrow bar width and flared drop brings your arms closer together when on the hoods for reduced drag
- Shimano Dura-Ace Di2 with 11-30 cassette and 52/36 crankset
- Full carbon HolloGram 64 KNOT wheelset
