In astonishing footage rider Michael Guerra unclips from his pedals, lies down on the seat and stretches out his legs to achieve ultimate aerodynamic efficiency.
Letting go of a huge amount of control he lets the pedals spin all by themselves.
Although a rather risky manoeuvre his method clearly works as he begins to overtake his fellow cyclists. The fixed-gear Italian cyclist decreases his wind drag with remarkable skill.
He even shoots past an awe-struck man on a moped, who reaches to take a wobbly picture as he flies on by.
