Steel does seem to be an excellent choice for bike frames, Perhaps better then alluminum if we use good steel tubing (like thinwall cromoly).
Is it possible that the bicycle industry's marketing team had worked overtime, and sucessesfly convinced average consumers that alluminum bikes are better then steel to boost sales.
Then theres manufacturing cost. I'm not an engineer, But it wouldn't surprise me if it was less expensive to build good quality, inexpensive alluminum bikes then steel ones with the tighter tolerances and careful welding needed for thin tubing.
And while we could, and someone probably does build high quality, performance steel frame bikes to this day that might rival some carbon frame ones, Carbon might be the best choice for mass production.
