France's Francois Pervis retained his keirin title at the World Track Cycling Championships near Paris on Thursday.
It was the 30-year-old's fifth world title in total having won three gold medals last year in Cali.
He produced a blistering last lap to win clearly ahead of New Zealand's Edward Dawkins with Azizulhasni Awang of Malaysia in third.
Former world champions Shane Perkins (2011) of Australia and Britain's Jason Kenny (2013) crashed out in the qualifying rounds while Germany's Maximilian Levy (2009) of Germany managed only fourth.
