The February 1996 Bicycle Guide had an article about comparing 7 styles of Columbus steel tubing. None of the frames had tubing stickers or designations of any kind. The bikes were identical in geometry, components, and size, but were made from different styles of Columbus pipes. The frames were all made by the hands of Antonio Mondonico. Materials tested were EL-OS, Neuron, SLX, Brain, Thron, Cromor, & Aelle. The conclusion reached in the article was that the differences were very subtle and inconclusive.
The final statement of the article was as follows: "Perhaps more than anything, they illustrate that the personality of a bike is determined much more by the fit, frame geometry and the components than by what kind of tubing lies under the paint."
e-RICHIE is quoted with the now familiar saw: "When someone is buying a bike from me, they're buying my design choices and my construction skills. I actually think material is the least consequential choice."
Pipes don't make the bike! What the framebuilder does with the pipes MAKES the bike.

The problem is that builders often think of tubing in terms of guage instead of model designation. Thus a frame with Reynolds 531 but with a couple of Columbus tubes - well what guage Columbus tubes were used?

> Now, it would be a great project to identify ride charactersics and tube guage, but it is very difficult to find frames with identical geometry and known differences in tube guage (I bet some list members know some examples though!)
> In the one case where I did make a comparison, I had three identical Waterford frames except I ordered different tube guages for downtube and chainstays. The differences, especially when heavy chainstays were used, were very easy to feel when riding.
