I have FS a well used (about 10,000 miles) 2004 Cervelo Prodigy frame with stock fork (Cervelo), Ritchey stem, Cane Creek headset and Ultegra front derailleur. I rode this bike recreationally for a couple of years and raced it one year. I has dings and scratches and paint chips, but rides great. There is a pair of dents on the downtube from some aggresive bike mount clamps. I understand this is an easy and cheap fix by any local frame repair shop. Below is the info from Cervelo. Please pm for pics.

Introduction
Here’s a frame that will make you return to a steel frame for it’s great ride, or make you never leave to ride anything else. The Prodigy benefits from the extensive design work on the Renaissance and uses it’s most important design elements. It uses the same main triangle as the Renaissance, with a slightly altered rear triangle to make the bike more affordable. The result is a frame that offers most of the performance of the Renaissance for a fraction of the price. back to the top
Columbus** Custom Niva/Thermacrom Steel**
The Prodigy uses a custom Cerv�lo Smartwall tubeset made by Columbus. The
Thermacrom front triangle is borrowed from the Renaissance, while the
rear triangle is made out of Columvus Nivacrom. Below please find
Columbus’ information on the Thermacrom material.
Thermacrom is a steel micro-alloyed with manganese, chrome, molybdenum and vanadium. These elements produce a marked increase in temperability, a reduction in sensitivity to overheating which ensures that a fine-grain metal structure will be obtained after welding, more able to withstand fatigue stresses, better characteristics of strength and tenacity and better characteristics of resistance to corrosion and wear. After mechanical deformation working and drawing, Thermacrom undergoes a heating and cooling cycle that gives the steel its particular microstructure. The treatment, which only ends at the time of welding by the frame-maker, enhances the mechanical characteristics of the material by giving it high breaking loads permitting completely safe reductions in thickness. As the table shows, Thermacrom is far superior to any other steel alloy, as can be seen in the figure below:
Mechanical Characteristics:
Breaking load = 1250 � 1450 N/mm� Elongation > 10%

Comfort** Toptube**
To increase the stiffness of a tube, we need to increase the diameter. Decreasing the diameter decreases the stiffness. The top tube provides stiffness in two basic directions: It provides lateral (sideways) stiffness. Think of a bicycle, and what happens to the frame when you push on the pedal and pull on the handlebar. This is an attempt to torque the frame, pushing the top tube to one side and the downtube to the other. Looking at both tubes, it can be seen that this torque attempts to move both tubes laterally, be it in the opposite directions. To counter this, both tubes need lateral stiffness. For the downtube (which is in a complicated load situation of combined torque and bending), we achieve this with differential butting or bi-conicalization. For the top tube (which is in a simpler load situation of almost pure lateral bending), we can achieve this by increasing the diameter in the lateral direction. The top tube provides in-plane (vertical) stiffness. Thanks to their structure, all double diamond frames have ample in-plane stiffness. We would even like to decrease this stiffness, which can be achieved by decreasing the vertical diameter.
Combining these two features of increased lateral diameter and decreased vertical diameter, we obtain a top tube that is ovalized. back to the top
Bi-Conical** Downtube**
For an extremely light steel bike such as the Prodigy, it is very important to use the material in an optimal way. This means using a large diameter thin wall downtube. Unfortunately it is not possible to use differential butting on a steel tube the way we do on our Aluminum aerotubing, but there is another way to increase the stiffness of the downtube: through bi-conicalization.
This means that near the bottom bracket, where we need lateral (sideways) stiffness, we have ovalized the downtube so that the biggest diameter is in the lateral direction. Near the front, the downtube is ovalized to become as wide as possible while still fitting on the headtube. The transition between the oval cross section near the bottom bracket and the one near the headtube is fluent, so that the stresses are transferred through the tube optimally. This means that the downtube isn’t just locally ovalized, but it is ovalized throughout the entire length, thereby slowly changing shape from one extremity to the other. back to the top
Nickel** Plating**
The entire frame undergoes a nickel plating treatment to increase its corrosion resistance, not just the areas of the rear triangle and decals which is left exposed.While this treatment protects the outside of the frame, we do recommend regular treatments of the inside of the frame with products such as FrameSaver. back to the top
