From Best, To Superior

How do you go from best to superior?

By never settling for the status quo. Cannondale has taken all that's best about the SuperSix - a bike that as recently as March 2009 won accolades from the rigorous test editors at Germany's prestigious Tour magazine, achieving maximum points in the best power transmission category - and made it superior to our competitors' offerings.


Cannondale Supersix

A Bicycle Built For You

Cannondale Supersix When you make a high performance road bike both lighter and stiffer, the benefits are clear:

  • Better power transfer
  • Faster sprints
  • Easier climbs
  • Less fatigue at the end of the ride
  • Quicker response
  • Improved steering precision
  • Intuitive rider positioning
  • Maximum performance

The Improved Engineering Behind The Ride Feel

When we say new and improved, we mean it. For 2010 the Supersix boasts significant weight reduction, improved carbon design and engineering and many improvements in the front triangle - including the headtube, bottom bracket, chainstays and seatstays.

Weight reduction: We've shaved more than 150 grams from the frame, counting grams everywhere. Frame weight is 900g in size 56cm with paint and hangers

Carbon Fiber improvements:

Cannondale engineers maximized the anisotropic properties of carbon fiber for the ultimate in performance. Unidirectional fiber is used throughout the SuperSix with overwrapping of critical tube junctions. Carbon Overwrapping is a superior method for attaching the rear triangle to the front triangle for three reasons:
  1. Overwrapping weighs less than lugs; there is less overlap of material and the wall thickness of the overwrap is much less than a traditional lug.

  2. Overwrapping also spreads the connection loads onto a larger area of the front triangle, while lugs concentrate these stresses into smaller areas, which requires more material to maintain the same strength.

  3. The one-piece rear triangle reduces the amount of overwrapping necessary for greater stiffness, efficiency and power transfer.

Front Triangle improvements:

  • Headtube: The SuperSix uses carbon cups to hold the bearings. Tube widths are maximized at the head tube junction for the ultimate in force distribution and steering precision. The flowing lines allow continuous lengths of fiber to connect the top tube to the head tube to the down tube. This stronger method allows us to use less layers of material which saves weight. The lower headset bearing is directly supported by the down tube fibers; this creates a stiffer frame using fewer fibers (to shave weight). The SuperSix features a deep radius head tube for better steering precision. The wide, non-round DT fits flush against the HT for steering precision; oversized at BB for torsional rigidity.

  • Bottom Bracket: "The Heart" continues to "Beat." Stiffness/weight in the BB rigidity test has improved by 17 percent. Cannondale's trademark oversized BB junction - now called the "Beat Box" - remains, but we've improved performance. The oversized "Beat Box" minimizes torsional flex due to loads from the crankarms while a clamp-on front derailleur allows flexibility for riders who prefer to ride with compact cranks.

  • Chainstays: Because chainstays are subject to different loads on the drive side and non-drive side, they're asymmetrical. The drive side chainstay sees high axial loads from the chain, so a tall cross section is spec'd to give the best possible power transfer. On the non-drive side, bending loads from the chain necessitate a wide profile to maximize bending resistance. Drive side: 54mm tall by 16mm wide at BB; tapers to 25mm by 19mm wide near the dropout Non-drive side: 49mm by 18mm wide at BB; tapers to 25mm by 21mm wide. And because asymmetric chain stays optimize power transmission, the cross sections of the SuperSix chainstays have been increased by up to 10% to give riders superior power transfer to the rear wheel.

  • Seatstays: Hourglass seatstays have just enough yield to dampen high-frequency road buzz found on many carbon frames - but without feeling sloppy or undertuned. This has given our world class racers greater rider comfort during 200k stages and our everyday riders the same, regardless of distance or speed. Through kinematic modeling, our engineers have maximized tube cross sections and carbon lay-up to make those long rides even more enjoyable.

The 2010 SuperSix: Clearly The Weapon Of Choice

  • Lighter weight for faster response
  • Faster sprints
  • Better power transfer
  • Lessens stress on the frame and steering precision improved with head tube design
  • Gives familiar rider position and maximum performance
  • Easier to climb
  • Less fatigue at the end of the ride, with hourglass-shaped damping stays
  • Simply Beautiful

The Analysis: Aerodynamics

Aerodynamics do matter, and the Slice's aerodynamic values are class-leading according to third-party tests.

As you know, some companies in the industry claim that aerodynamics can shave seconds from race times. That's great for wind tunnel testing. But to focus solely on aerodynamics doesn't tell the whole story; in real-world riding, the bike and components cause about 30% of the drag, while the larger frontal area of the rider causes more than 65%.

Other 'real world' factors to be considered include friction, inertia, rolling mass, kinematic frame response, wind speed, rider weight, rider position, rider power output, gravity, and many more.

On level courses, minimizing aerodynamic drag is important at speeds above 15mph. But for triathletes riding up inclines, overcoming the force of gravity outweighs aerodynamic gains. This is why lowering the total bike mass is also vitally important. Tour magazine editors agree.

The Analysis: Weight

Lower bike weights = faster race times! The Slice was the lightest in Tour's tests by a significant margin.

It was no contest: Cannondale Slice was found to be the lightest of the group, beating the Kuota by 15 grams and the Scott Plasma by nearly 100.

This is no minor point of differentiation since every gram that can be stripped from frame weight has the potential to shave significant times during Ironman-distance races.

All variables being equal -- and assuming that a rider is capable of constant power output -- our formula for shaving every last gram is based upon the following calculation:

What about comfort?
Comfort is critical to triathletes. The Slice's Aero Vibration Damping allows them to stay lower for longer periods, and keeps their bodies fresher for the run.

The TOUR-method for performing frame comfort and compliance testing uses a defined force applied to the frame with the fork mounted; deflection is measured where normally the rider's sit bones would be. The test is dynamic and therefore non-destructive.

Although Tour magazine did not test specifically for comfort during this round of testing, Cannondale has performed in-house testing similar to Zedler's methods to gage the kinematic response of the Slice's SAVE features.

The results were stunning and perhaps best qualified by the sentiments of our world class athletes, including two-time Ironman World Champion, Chrissie Wellington following long-term ride testing on the Slice:

"I feel super relaxed and powerful down in the time trial position, and have even gone a little lower than I was before. The [Slice] is incredibly smooth, very responsive and takes the strain for me - eliminating any vibrations and leaving my legs stronger and fresher for the run."
