Keep in mind you're comparing two bicycles of a different size.
For apples to apples comparison, here are some published wheelbases.
23" Le Tour: 40.75"/1035.05mm
22.5" 520: 1056mm
I took a guess that the 23" Letour is about the same as a 22.5" 520, but if it's more like a 24" 520 then the difference is even larger. 36mm or almost 1.5"! Admit it, the Le Tour isn't a touring bike!
23" Le Tour: 40.75"/1035.05mm
24" 520: 1071mm
