I don't know if it might work for what you are looking for (racing handles and straps), but when I had my carbon poles destroyed, I then went to the shop where I had bought them and asked if it was possible to get some spare parts to try to make then usable again: handles, basket, and tipss. They got them, had to pay of course, from their LEKI sales rep, and those were real spare parts not some refurbed parts hastily found. But those were normal spare parts and the shop was not a racing oriente one. Try and go to a ski racing specialized shop that sells LEKI and see if they can work that out for you. Even while in Switzerland. Since it might take a while, you better (if you know the names of a shop or two) work that out in advance.
