Highlights
- Ultra low drag Hi-MOD BallisTec carbon frameset / Integrated Cannondale App connectivity
- Ultegra Di2 electronic shifting / HollowGram crank
- HollowGram 64 SL KNØT carbon wheelset / KNØT SystemBar
SystemSix outstrips opponents, and not just where you’d expect. It sprints, descends and even climbs most hills faster, conserving watts off the front, in the draft, and in the laughing group.
SystemSix is a holistically designed, six-part system wholly dedicated to the pure pursuit of speed. It generates the least aerodynamic drag of any road bike on the market, which means more speed, in more situations, for more riders. It’s faster everywhere.

Technology
Cannondale KNØT SystemBar
Provides the low drag and sleek look of a one-piece system, with the fit and Interchangeability benefits of a two-piece bar and stem.
HollowGram 64 KNØT Wheels
One of the fastest wheelsets ever created. Ultra-wide, disc-only design offers incredibly low drag at a wide range of yaw angles, even with larger volume tires.
HollowGram 60 KNØT Seatpost
An vital part of the system, the KNØT seatpost is designed specifically to reduce drag in the high speed airflow that is accelerated between the rider’s legs.
Customized Airfoils
Every section of the frame, fork and seatpost features it own customized truncated airfoil shape, designed to reduce drag across the effective yaw range.
Hidden Cable Routing
Unique design routes brake lines and cables through an opening in the front of the headtube for minimal drag and headache-free serviceability.
Connected
An integrated wheel sensor delivers hyper accurate speed, route and distance info, registers your bike, reminds you of needed service and more, all through the free Cannondale App.
Speed Release Equipped
The Speed Release thru-axles allow faster, easier wheel changes and are compatible with most standard thru-axle wheelsets.
BallisTec Hi-MOD Carbon
Cannondale's premium high-strength, high-stiffness carbon construction. A sophisticated blend of high-strength and high-stiffness fibers yields a frame that’s extremely light, lively and durable.
