I have not been able to find tubing akin to what titanex uses.... By the way I
have 18 Titanex in the air. (and lots of scrap on the ground). If someone needs
a piece or two for a repair let me know.This stuff is some alloy... very hard
...very light. The pure titanium on the price sheet given below is not it. The
titanex tubes have a seam... and go do not telescope directly ... they use
various aluminum adapters.
