The Dragonfly tube set was designed to build the lightest possible single and tandem bicycle frames without sacrificing stiffness, durability and ride quality. <BR><BR>Calfee uses 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, but Calfee 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.<BR><BR>The use of boron fiber has come of age with its use in our high performance bicycle frames. Bicycle weights have dropped from 18 pounds back in the 1980s to 14 pounds or less. Much of this weight savings comes with the use of carbon fiber composites. As bicycle companies compete in the arms race to make even lighter, stiffer bikes, safety and durability are pushed to the limit. High modulus (55 Msi and greater) carbon fiber is being used to make stiff yet thin walled tubing. These tubes can be vulnerable to damage from a variety of real world sources. When slightly damaged from a pebble thrown up by a passing car, or an unfortunate event during a group ride or race, a thin walled tube can rapidly degrade to an unsafe condition. Using boron filaments in the tube laminate mitigates this problem by significantly enhancing the tubes structural performance.<BR><BR>The Calfee Dragonfly weighs only 2.1 pounds in a 54cm size, delivers power as well as any large diameter, thin wall frame, has superior vibration dampening, compressive and impact strength, and is protected by a 25 year warranty.<BR><BR>Dragonfly single and tandem lugs are pressure molded from high modulus fabric. With Dragonfly singles, lugs are made with carbon fabric formed around metal mandrels. These lugs and pre-mitered tubes are easily bonded together because they are so compatible. The carbon fibers are carefully oriented to put strength exactly where it’s needed while minimizing weight. Gussets are integrally formed with the fabrication of the joints, eliminating the inherent weakness of the tube and lug joint found in many other manufacturers designs. 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.<BR><BR>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 build 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.<BR><BR>A full listing of options and prices can be seen at: http://www.calfeedesign.com/product/single-frames-pricing<BR><BR>Calfee frames are only available at the Reparto Corse Fitting Studio.

<a href="http://store.repartocorse.com/Product3527" title="Calfee Tetra Frame">Calfee Tetra Frame</a> -- The Tetra tube set and road frame was originally designed in 1987 and has been thoughtfully refined to its current incarnation over the last 23 years. As the oldest continuously produced model of carbon fiber bicycle frame in the world, it has evolved to a state of perfection and value unmatched by any other frame.
Even bicycle enthusiasts and industry insiders are surprised to learn that Tetra was invented back in 1987 and only four years later was being ridden by Greg LeMond and his Team Z teammates in the world’s most important cycling event, the Tour de France. Greg wore the leader’s Yellow Jersey aboard our Tetra, then less than five years old. Today, nearly 20 years later, Tetra tubing and bicycle frames have been continually optimized; sharpened by improvements in raw materials, manufacturing processes and advantageous frame options.
With the Tetra frames, Calfee saturates carbon fabric with epoxy, then laminates it at 210 p.s.i. and fuse it to pre-mitered carbon tubes using metal dies. Molded in one layup, the resulting joints have long tapered transitions from one tube to the next, following the stresses evenly. This manufacturing process seamlessly marries their tension filament wound carbon tubing resulting in a frame without molded lugs. Fatigue life for these fiber reinforced joints is appreciably longer than that of adhesive bonds and, coupled with the tubing itself, is grounds for the Tetra’s 25 year warranty.
The Tetra tubes were designed to have the optimum stiffness to weight ratio and also have a thick enough wall to be impact tolerant. The 42 and 55 msi modulus fiber is strong and very stiff but not too brittle.
The precise orientation of the Tetra’s 51 million fibers delivers the best combination of stiffness and comfort for everyday riding. While these frames are unbelievably stiff through the drive train and are very light (2.4 pounds for a 54cm single and 6.8 pounds for a Medium/Small tandem), they are especially easy on the saddle and handlebars. These qualities conspire to make Tetra the choice of traveling tandem teams, privateer racers, endurance road riders and gravel-road randonees.
Of the 5000 or so frames Calfee has delivered to bicycle riders these last two decades, over 3400 have been Tetras. More than any other Calfee innovation or product, Tetra is responsible for Calfee’s unassailable strength and position in today’s crowded carbon market.

<a href="http://store.repartocorse.com/Product3526" title="Calfee Luna Frame">Calfee Luna Frame</a> -- The Luna was conceived as a model to compete with the bigger brands. The amazing Luna, built by Calfee at their headquarters in California, retails for less than frames made offshore in China and Taiwan. Still, it shares the workmanship, hand crafting and ride quality of their more expensive frames.
The Calfee Luna frame shown is done in their nude finish with a PressFit 30 bottom bracket shell and the S and S Machine coupler frame option. This frame, though fitted with couplers, weighs only 3.5 pounds. The industries most affordable, US made carbon frame, the Luna is popular with price sensitive riders looking for a unique, high-performance bicycle that, though relatively inexpensive, refuses to compromise; legendary Calfee ride quality for less than frames made in China and Taiwan.
Like the flagship Dragonfly, Luna’s lugs are compression molded with metal dies. These lugs and pre-mitered tubes are easily bonded together because they are so compatible. The carbon fibers are carefully oriented to put strength exactly where it’s needed while minimizing weight. Gussets are integrally formed with the fabrication of the joints, eliminating the inherent weakness of the tube and lug joint found in many other manufacturers designs. Calfee saves some labor expense on the Luna expense, by not scalloping the lugs as on the Dragonfly. Luna lugs wrap uniformly around the circumference of each tube. Luna frames, though inexpensive, are very light; 2.8 pound for a 54cm road frame.
Luna leverages a purposeful blend of standard modulus 33 msi carbon fiber with some intermediate modulus 42 msi fiber to achieve Calfee's famous ride quality. These seamless, tension filament wound tubes have been optimized to transfer power without transferring vibration through the pedals, saddle and handlebars. Luna frames are as laterally stiff as the Tetra and are nearly as comfortable. What the thicker walled carbon fiber tubes give up in absorption, they make up for in durability as they resist compressive and impact forces better than our Tetra and Dragonfly tube sets.
Owing to this durability, Luna is ideal for off road and travel applications. The Luna Cross (CX) is one of the lightest, most durable and most versatile carbon cross frames on the market. The CX model weighs three pounds in a 54cm and features top tube cable routing, a PressFit 30 carbon bottom bracket shell, titanium dropouts and mechanical or hydraulic disc brake compatibility.
The Luna is available for road, cross and single speed set up.
