Frame and Bike Pricing. The Dragonfly tube set was designed to build the lightest possible single and tandem bicycle frames without sacrificing stiffness, durability and ride quality. Please read this review of our Dragonfly published in the June 2011 issue of Road Bike Action. We use high modulus carbon fiber (66msi) in all the tubes as well as the lug areas. 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. Boron is an attractive reinforcement because the resulting composite combines superior tensile, compressive and flexural strengths, high modulus, and low density in one system. 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.
This Dragonfly features a stirring paint scheme; we sprayed translucent blue-pearl on all frame components finished in a traditional carbon weave (lugs, bottle bosses, brake bridge, cable guides) and translucent rootbeer (actually a tangerine) on the tubes. This paint job retails for $660.
This Dragonfly features a host of product from our tubing supplier, ENVE Composites, including the bar, stem, fork, seat post and wheels. Other highlights include our full-carbon BarStem and our Di2 Internal Battery and Wiring System.
