Firstly, please sign your first and last name to your posts so that we know who you are.

Secondly, there is no such thing as aluminum fatigue, or fatigue of any other metal for that matter, unless subject metal has been stressed to some degree beyond it's elastic limit, or subjected to excessive temperatures such that its molecular structure has been permanently altered, resulting in a modification of that metal's performance characteristics.

The bars photographed are GB Tourmalet, although I would argue that the Ventoux model is quite a bit more difficult to find. Both were produced from the 60's through early 70's. they featured an internal reinforcing sleeve housed within the center bulge section.
