Olympic champion Jason Kenny won the men's sprint title at the track cycling world championships here.
Kenny, who looks to defend his individual and team sprint titles at the Olympics in Rio de Janeiro, on Saturday edged Australian Matthew Glaetzer in a third-race decider at the Lee Valley VeloPark where he became an Olympic champion in 2012, reports Xinhua.
The British rider lifted his second individual sprint title after he was upgraded to the 2011 gold medal when Gregory Bauge's results were wiped out after he was banned for missing doping tests.
Defending champion Bauge was sixth, finishing his competition without a medal.
In the omnium event, Colombian Fernando Gaviria made a successful defense after the sixth and final event, the points race and collected 191 points to win.
German Roger Kluge and Glenn O'Shea of Australia ended on the same total but the result was decided by the order they finished in the 10th and final sprint.
