People go nuts for this tubing.
And for classic Rossin frames.
Here is a bit of info. taken from an article all about tubing (Smart Cycles.com):-
But…. there was something truly special waiting for those that bought bikes made of EL-OS. EL-OS was 0.7mm at the butt and drawn down to 0.4mm in the center section. First of all, there was a reduction in weight, about 1/4 pound. That’s always nice. The biggest bonus was in how the bike felt. Anyone who has ridden an EL-OS bike built by a good builder understands what a supple, beautiful, wonderful bike really is.
The problem was that getting a 0.4mm tubeset bike was expensive. Even now, almost a decade later, there are tubing companies that do not even have the technology to draw a 0.4mm tube. Even though Columbus can now draw 0.385 (a reduction of 15 thousandths of a millimeter from 0.4mm), I think we can safely say that 0.4mm is still the state of the art.
This frame set is really desirable and super light. It will perform and make your eyes whirl and heart beat.
It’s finished in a slightly deeper tone than Ferrari red. It’s been fillet brazed.
It’s going to very sexy when it’s built up.
Don’t tell Rob, but imagine this with a new groupset fitted, it would be mean.
