Fair enough, still, "Roubaix" meaning "gravel" is like "Alaska" meaning hot and dry. There's no gravel between Paris and Roubaix. But I guess that's partly the difference between cycling slang in the States vs somebody from Europe.

What you call "Roubaix" is actually "Strade Bianche", the Italian gravel spring race...





This is "Roubaix", the cobblestones...
