"THE CANNONDALE FRAME"
At Cannondale, we've looked at bicycling from the cyclist's point of view for years. Now we have built a revolutionary bicycle frame that is ideal for long distance touring, time trailing, and everything in between.
"ABOUT ALUMINUM AMD LARGE DIAMETER TUBING"
We selected aluminum alloy for our frame only after careful study of the several materials available. Tradtional steel tubing has served the cyclist well, but has always meant a compromise. To get the stable ride of a long wheelbase, cyclists have had to put up with a whippy (and often wimpy) frame. As a result, many cyclists are under the misconception that flexibility is desirable in a touring frame. The fact is, however, that the more flexible the frame, the less efficient is each pedal stroke. Energy that should be transmitted to the wheel is wasted flexing the frame, causing a sluggish, tiring ride.

Equations comparing aluminum to Reynolds 531 for stiffness and strength. "FRAME CONSTRUCTION"
From the drafting table to your local bike shop, the Cannondale Sport/Touring bicycle is the product of intelligent design and careful craftsmanship. Every step in our production process has been developed to assure that a Cannondale frame represents fine American quality. Construction is performed entirely at our factory in Pennsylvania by trained, highly skilled personnel. They take pride in the quality of their work, so we can be certain each frame meets our strict standards.

"FRAME GEOMETRY"
The Cannondale Sport/Touring bicycle frame has been designed to give a versatile combination of touring performance and efficient response to pedaling. We have combined carefully selected geometry with the strength and stiffness properties of large diameter tubing to create a bicycle frame that offers a stable, responsive ride, making it ideal for many types of cycling. |
