Show us your Titanium! - Ti and Stainless bikes

Quote Kent Eriksen .. "We use 3/2.5 straight gauge tubing from Sandvik and Haynes. We have done a few bikes with butted tubes, but it takes away a lot of stiffness and we normally suggest going with a thinner wall straight gauge tube as it will give a more consistent ride quality and maintain the integrity of the bike a bit better."

I find these difficult to accept as the words of an engineer.
