It takes a system.

To say the SystemSix represents a unique approach to aerodynamic optimized bike design would be a bit of an understatement. Our holistic approach to speed represents the pinnacle of what a race bike designed from the ground up can really deliver. Ground up? Indeed. The entire SystemSix project began with a quest to design the fastest wheel possible for modern tire volumes. And we built from there, developing the frame, fork, seatpost, bars, stem and wheels together as a complete speed system. Taking full advantage of disc-only optimization. Tailoring frame tube profiles to control airflow at every point. Developing a bar/stem combo that delivers the fast without forgoing the fit. Yielding the most positive wind tunnel data we’ve ever seen. And all within UCI limits.

The Foundation of Fast.

The most important part of the world’s fastest system, the SystemSix frame and fork are the rock upon which speed is built. Every tube shape painstakingly engineered to be as immune to drag as possible. Purposeful asymmetry for instant response to disc brake and pedaling loads. Impeccable handling and classic road race feel thanks to geometry derived from our gold standard EVO. And of course, scores of refined details designed to speed you up and not let you down.

Optimized Against Every Aspect of Drag.

Foiling Drag.
Every section of the frame and fork features tailored airfoil profiles, with differing degrees of truncation designed to maintain flow attachment across important yaw angles and minimize drag.

The Chine.
The unique chine shape at the base of the headtube redirects air flow coming up the back of the fork leg, channeling it downstream. This prevents the fork's airflow from mixing with the wake of the head tube and interrupting clean air over the fork crown.

Sleek as Fork.
Freed from the constraints of rim brakes, the fork crown area is radically different from traditional road bikes. Sleekly integrated with the frame for minimal drag. Larger opening for bigger tires and cleaner airflow. Asymmetric legs for handling disc brake loads.

Bigger Meet Better.

Conceived as the first component of the SystemSix project, the HollowGram 64 KNØT is one of the absolute fastest wheelsets on the planet. Its unique design combines the speed benefits of an ultra-low drag profile with the real-world rideability benefits of larger volume tires. Incorporating some ideas pioneered by our friends at HED, the disc-specific design is significantly wider than other road wheels. That extra width both makes tires effectively bigger than their marked size for better ride quality (a 23c tire measures a full 26mm on our wheel), and helps air flowing over the tire reattach cleanly to the rim, maximizing flow attachment and minimizing drag. The rim shape is optimized for 26mm (23c) tires, but the 64 KNØT design exhibits minimal changes in drag with even larger tires, giving riders the option to go bigger for comfort, grip and reduced rolling resistance without paying an aero penalty. It’s pure speed, without compromise.

System of Control.

The KNØT SystemBar is a slick bit of speed wizardry, providing the low drag and sleek look of a one-piece bar and stem, with the customizable adjustability of a two-piece system. The carbon bar features a full 8° of pitch adjust, so you can dial in your perfect position. And the rounded truncated airfoil shape of the flat section not only maintains consistent airflow throughout the pitch range, it’s also way comfier on your hands than the sharp trailing edge of other aero bars.

In addition to giving the bars a place to perch, the mating System Stem routes brake and Di2 lines cleanly into the headtube via a channel underneath a mechanic-friendly removable cover. And speaking of mechanic-friendly, shape-matched gated spacers allow you to easily adjust the stem’s stack height, without having to disconnect cables. Fast and easy, just how you like it.

The Most Post.

It's a common misconception that seatposts are insignificant to performance. In actuality, the airflow in this region is significantly faster than the clean air at the front of the bike, due to the flow accelerating between the rider's legs. The truncated airfoil shape of the SystemSix post is a big part of the world's fastest speed result.

  1. Power2Max power meters

    Most models come with Power2Max spider-based power meters, which are light, accurate, and, above all, reliable. A one-time activation fee is required to turn it on, after which you're ready to speed away to your heart's content.

  2. Customized airfoils

    The customized truncated airfoil shape in the frame, fork, and seatpost of the SystemSix has been carefully designed to reduce drag across the effective yaw range. The shape of the downtube and seat tube also minimizes the aerodynamic effect of bottles, so you'll feel lighter than air.

  3. Concealed cable routing

    The SystemSix's unique design routes the brake lines and Di2 cables through an opening in the front of the headtube, thus bypassing the headset bearings. Damage to the cables is prevented by an integrated steering stop, which also permits a full +/- 50 degrees of steering rotation (regular riding rarely requires more than 35 degrees of movement).

  4. Cannondale KNØT bar and stem

    The SystemSix boasts the low drag and sleek appearance of a one-piece system, while offering the fit and interchangeability advantages of a two-piece bar and stem. 8 degrees of pitch adjustment. Reduced drag, thanks to the narrow bar width and flared drop, which brings your arms closer together when on the hoods. Removable cable cover facilitates easy setup.

  5. Speed release thru-axles

    The SystemSix's frame and fork are equipped with Speed Release thru-axle standards, which are compatible with any standard thru-axle wheel set. Changing wheels is faster and easier than ever, meaning one less thing for you to worry about.
