Ok folks I think this has been said before but people don't seem to remember. 4130, 531, 501, 555, 753, etc. . . . is not the designation of the tubing. What these numbers refer to is the steel itself, the make up and each number is a designation of the different metals within the steel. I used to know what each number meant, but have long forgotten. . .any material engineers out there? All of these steels can be drawn into various "tubing sets", for example Reynolds 531 has had at least three different butting variations that I know of, including an unbutted 531 tubeset. To the OP, yes 4130 is just a designation for a type of cro-mo steel and Raleigh has used 4130 for a long time. I think, but I'm not 100%, that all the bikes built with "Raleigh steel" drawn by reynolds are 4130. enjoy, Brandon"monkeyman"Ives SB, CA
