520 Steel?
I just purchased a new inexpensive RB made of 520 steel. The ride was smoother than the AL bikes I test rode, including a LeMond, Specialized and Bianchi which were steel. This new bike rides as good as the old Peugeots and Motobecanes I rode in the late 1970s. What is the history of 520 steel and how is it viewed by builders? Do the French and Italian builders use 520?
Thx

Just about any decent, steel bike is going to ride smoother than one with an aluminum frame.
I believe 520 and CroMo are the most popular steel tubes for frame building. I'm guessing it has to do with weight vs. structural integrity, (i.e. - you can use thinner walled tubes but not end up with an unsafe bike).

Before repainting my 1986 Raliegh, I think I remember a 400 and something number and maybe the words, "Hi-tensile."
I've repainted several bikes, so I might be confusing/combining the stickers from different ones.
Someone correct me if I'm wrong, but the numbers coincide with the percentages of iron and other metals are in the mix.
