Mort,
Try looking at Rootboy's hand made tyre savers (he is usually in the C&V Forum) I got 2 pairs from him, they are brass or stainless steel and surgical tubing (very high grade). He makes these his self and sells them. One of the C&V publications did a review of them and will begin selling them shortly. He is a first class guy and has done some beautiful builds of C&V bikes. Do a search in C&V for him/them. They can be adapted to fit using some creative extra bends.
