Came across this article yesterday discussing the development of a lighter, yet stronger, steel material that can be manufactured into bike tubes. Will be interesting to watch the development of these since I love steel bikes and am really curious to see what this could turn into.

New steel could be stronger and lighter than titanium

There is already a thread about this on the road cycling forum https://www.bikeforums.net/road-cycli...-titanium.html

The page would not load but I think this is the material where aluminum and a trace of other elements are interspersed within the steel. At this point I surmise that connecting the tubes together would be similar to working with carbon fiber tubes.

Interesting - got it to load here.

Yes, it's got aluminum in it with traces of nickel to solve the problems they've had in the past with brittleness after adding aluminum:

From the article:

"They’ve done this by using a brand new recipe for steel. All steels contain several ingredients – iron and carbon are essential and then there are varying quantities of chromium, molybdenum, manganese, silicon, sulphur and phosphorus.But the new metal also contains a big helping of aluminium, which is much less dense than iron and similarly cheap. People tried making high-aluminium steel before but the end result was too brittle.
The South Korean researchers, though, have added a dose of nickel to the mix and created tiny crystals inside the steel which stop any nano-scale cracks from spreading."
