Titanium tubing

Titanium tubing

(OP)
Could anyone tell me if the spiral twisting top and down tubes on the Lynskey Helix frame actually
adds anything in way of stiffness and handling that a conventional tube would not.

Here's the frame in question. http://www.hotlines-uk.com/lynskey-helix-ti-road-f...

Many thanks

RE: Titanium tubing

Seems more of a marketing gimmick. It's probably OK for a city street.
The top and bottom tubes are twisted in opposite directions. They probably do this because to balance poor torsional stiffness if they were the same twist.

Many thanks. So just a gimmick then.

RE: Titanium tubing

I have done a little more searching and found that Litespeed was founded by members of the Lynskey family.
They did some contracting and consultancy work for NASA on the Mars Curiosity Rover.
I have still not found any evidence that the twisted top tube is anymore than a gimmick as it does not appear Litespeed have ever produced twisted tubing on their frames.
