The UCI World Championships have thrown up some of the most memorable moments in cycling. With the help of our Italian photographer correspondent Sirotti, we take a look back at some of the most iconic riders and races from the last 30 years.
Sirotti has been photographing cycling races for a number of decades and has provided the sport with timeless photos. In this selection we pick out some of our favourites: from Armstrong to Bugno, Lemond to Fignon.
There are also shots of a very young Maurizio Fondriest before he won the worlds title in Belgium in 1988 and and even younger Lance Armstrong after he won in Oslo in 1993.
Sirotti also travelled to Duitama, Colombia in 1995 to capture Marco Pantani, as he tried to win the world title on one of the toughest courses ever used. Abraham Olano won, ahead of Pantani and Miguel Indurain.
There are also images of Mario Cipollini winning in Zolder, Belgium in 2002 and of Tom Boonen's perfect sprint in Madrid in 2005.
More recent images recall Cadel Evans victory in Mendrisio in 2009. Evans celebrated and so did his partner Chiara, confirming the unique emotions of the World Championships.
