Teun Mulder upset French hopes of gold to claim the kilometre crown here at the world track cycling championships on Sunday.
Mulder set a time of 1min 01.332sec for the four-lap race against the clock to claim the title ahead of French duo Michael D'Almeida and Francois Pervis.
D'Almeida provisionally led the field in a time of 1:01.514 but Mulder, a bronze medal winner in the keirin, was half a second faster after the first lap and went on to push the Frenchman off top spot.
Pervis was the last to start and looked to have one hand on the gold but he let slip the slimmest of leads during the final lap.
His third place finish pushed Britain's Matthew Crampton down into fourth place, after he had set a promising early time of 1:01.822.
Defending world champion Chris Hoy of Great Britain did not take part in the race known as the kilo, having given it up in favour of the keirin and sprint.
Hoy, the winner of the keirin and sprint crowns here, is also the reigning Olympic kilo champion however the event has been taken off the Olympic programme.
Mulder's second career world title comes three years after he won the keirin gold in Los Angeles.
But he admitted Sunday's race was not even on his agenda.
"I didn't want to race today but the coaches told me that I had to because I had form," said Mulder, who has been racing all week in the various rounds of the sprint and keirin.
"I didn't even have the proper kilo handlebars for my bike, I had to borrow them from one of the girls (in the team).
"So I didn't have any pressure. I basically raced for fun."
Since he is an established sprint and keirin rider, Mulder hasn't trained for the kilo for three years.
D'Almeida had done only two events in the four-lap race this year but that didn't stop him posting a personal best to claim his first ever world championship medal.
"I don't know anything about how Mulder prepared, but he's a far more experienced rider than me and I'm much younger," D'Almeida, whose previous best was 1:02.300, told AFP.
"Whether you train or not, if you can go fast you can still do well in the kilo."
