"As noted, it is a chromoly 4130 with heavy components. However, good alloy wheels. The total weight was only about 26-27 pounds, which is reasonable."

I'm getting confused here now. From what I have read elsewhere the "World" was not a chromoly frames set and did not offer alloy rims. Am I wrong in seeing the "World Sport" as a step up in the linage and outfitted with lightweight items as opposed to steel rims and the such. I know both versions offered alloy cranks but doesn't the similarity end there?
