I was looking for a solution to protect the TT on a few of my bikes, I had been using some pipe insulation and have seen some TTP's that looked like rubber/composite. Doing a search and adding BikeForums at the end resulted in a few old threads. I ran across one that mentioned clear 1" tubing but also tagged "Kashimax".
Members we complaining about the $39.00 cost (2007). I agreed with them about the high price but googled it anyway... to my surprise a "vintage" one sold on Bay for $200.00,

The new stuff is $60.00, any idea why the higher price on the Vintage piece?
$60.00 is still crazy money so 1" clear tubing seems like the way to go.
Best, Ben
