2 Dedacciai was established in 1992 with the aim of manufacturing state of the art steel tubing for bicycle frames. Zero / Zero Uno 2

Today s result of a more than quarter century of development and sport success is summarized in the current catalogue of high performance steel tubing.

3 Today s result of a more than quarter century of development and sport success is summarized in the current catalogue of high performance steel tubing. Dedacciai frame tubing are available in two classes: ZERO class tubing, state of the art light tubing, for racing and high performances frames, ZERO UNO class tubing, designed and engineered for commuter and long range users. All our steel tubing are seamless, manufactured in our plant in Italy, using en CrMo4 steel made in europe. To obtain the best results from the use of this class of products, please look carefully at the drawings, and read the advices at the end of this catalogue. 3

Assembling of the tubing Geometrical features All the Dedacciai tubes and tube sets are designed for assembling frames based on current UCI geometry.

22 Assembling of the tubing Geometrical features All the Dedacciai tubes and tube sets are designed for assembling frames based on current UCI geometry. In the choice of tubing for manufacturing a frames, please keep into account the following safety rules: Verify that for the selected geometry you will save a butt length longer than the thermal affected zone, and in any case longer that the tube diameter. If the butt length of down and top tubing butts are not symmetrical, pay attention in the tube orientation : at the head tube joint the tube must be only mitred, and not cut. Depending on geometry, it is always better to keep top and down tubing spaced on head tube. over imposed tubing geometries are less safe. road recommended tubing can t be used for offroad frames. Fixing point and welding cordons closure points can give origin to fatigue cracks, realize them in the less stressed areas of the joints. It is recommended to completely weld the seat tube on bottom bracket, and then all other tubing. Top tube and seat stays must be approximately aligned at the seat tube joint. If you want to weld the seat stays below the top tube center line, please use the low geometry (LG) seat tube Zero / Zero Uno 22

Welding and post-welding advices Before welding the tubing, carefully clean them and remove dirty and grease inside and outside of the tube in the area to be jointed.

23 Welding and post-welding advices Before welding the tubing, carefully clean them and remove dirty and grease inside and outside of the tube in the area to be jointed. The surfaces must be smooth and without notches.after mechanical cleaning, use acetone or MeK.Do not use chlorinated solvents. The suggested welding wire composition for TIG is C - 0.1% Si % Mn 1.0 % Cr 1.2 % Mo % (i.e. CASToTIG 6 / AWS A5 er70s-2 or similar) Welding wire diameter: from 1.0 to 2.0 mm. For brazing choose low melting temperature alloy, if possible below 5 C. Also the welding wire surface state is very important: stock it in clean areas, clean it before use and handle tubing and welding wire with gloves. Do not grind and/or polish the welding cordons. The risk of reducing the tube wall thickness is too high! Anticorrosion treatment is needed on the finished frame, cataphoresis is the most effective in long term protection As all the hi-resistance (> 1000 Mpa) steel, tubing in state HTS are sensitive to hydrogen embrittlement. Pay attention in avoid exposure to acid or hydrogen environments during frame fabrication. They can cause immediate and spontaneous breaks on tubing. In this case please contact our technical department. 23
