Cannondale’s website says “The R4000 Roller Blade was a fever dream concept bike, born in a time before UCI regulations shaped the bikes we all know today and designed with all-out aero gains in mind. In fact, only one R4000 Roller Blade was ever built, and reputedly only ever seen test-ridden successfully by one fearless man. And now, potentially by you too.”
