Our Lightest & Most Technically Advanced Frame

Dragonfly Di2 Integration

Although it weighs only 2.1 pounds in a 54cm size, they are plenty stiff and carry a 25 year warranty.  Our Dragonfly is a true, no-compromise frame.

The Dragonfly was designed to be the lightest possible frame without sacrificing stiffness, durability and ride quality. We use high modulus carbon fiber in all the tubes (55 msi) as well as the lug areas (42 msi). Previously, a frame built with all high modulus fiber would be too brittle. We incorporated Boron fiber into the three main tubes to add some toughness and compressive stiffness. Combined with the super high tensile stiffness of the carbon, the result is a frame material with the highest stiffness-to-weight ratio on the market.

The lugs are pressure molded from high modulus fabric. They are then meticulously carved to the optimum shape, taking into consideration the weight and intended use by the rider. They happen to look good because of their form-follows-function aesthetic.

The dropouts are also carved out to their optimal shape, saving 15 grams off the standard dropouts. This may not seem like much, but the way to make a 12 pound bike is to address every component and look for opportunities for weight savings, no matter how small. The trick is to do it without sacrificing strength and durability. As in nature, the Dragonfly is one of the most optimized and evolved structures to be found.
