This sounds potentially great, but I am skeptical. There are some big issues in terms of the usefulness of the bikes, mainly the flex issue that JS mentioned. Ti really didn't make a good track bike then (it is still not a common material because of the flex issue), so I see no reason someone would go through the trouble of building 20-30 frames out of a material that was probably hard to come by (anyone making Ti tubes then?), a pain to work with (still true), probably didn't make good frames (flex issue), and was really expensive. A couple just to try it out - maybe, if he was some technology geek who wanted to play around with the new supermetal. It is also my understanding that during the 1960s, almost all Ti was for the military, and people were just starting to be exposed to the material, so I am really unsure how he would have gotten the material to start with.

My guess? The frames are steel. I have had more than one person see a really nicely made steel frame and think it is Ti, because they are surprised by the low weight and quality. They think steel=Varsity, and don't realize you can make a really nice steel bike.

The frames still probably have collector's value as vintage pieces, but not the technology-ground-braking status they would if they were Ti.

Who knows, maybe they are Ti? This is a good story - keep us posted!
