Rather than name the builder let me give out clues and see who's the first to guess this mystery marque!
Non-America;
IMHO nice graphics;
An extensive history;
Had a range of models from entry-level racers to a top of the line professional bike that all but the most rabid Italophile would be proud to be seen riding (two clues there!);
Final clue for tonight: this mystery bike is featured on the CR website.
So what builder is this?
