Yes, we know that. But the question is what about their design makes them more suitable for the racing position? Can one take a cheaper model like the B17, B17n or Pro and modify them to be just as suitable for the "racing position"?
To put it another way: We've all seen the pictures of people who butcher their B17 or Pro to look like a swift or swallow, but do these butchered saddles also "feel" like a swift or swallow or are they still only suitable for a more upright riding position?
