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 off-road 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

• Alsotheweldingwiresurfacestateisveryimportant: stock it in clean areas, clean it before use and handle tubing and welding wire with gloves.
• Donotgrindand/orpolishtheweldingcordons.The risk of reducing the tube wall thickness is too high!
• Anticorrosiontreatmentisneededonthefinishedframe, cataphoresis is the most effective in long term protection
• Asallthehi-resistance(>1000Mpa)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.
