American Jennie Reed was crowned the world keirin queen after overpowering Britain's Victoria Pendleton in the final event of the world track cycling championships on Sunday. Defending champion Pendleton claimed the silver medal, with Germany's Christin Muche claiming the bronze after a photo finish decision.
Reed, a bronze medallist at Melbourne in 2004, claimed her first world title of any track event after pulling ahead of a four-rider bunch in the closing metres.
Pendleton appeared to run out of steam after launching a late charge having been at the back of the pack early on as the motorpacer brought the riders around the track.
It means Pendleton will not achieve a repeat of her feat last year when she won three gold medals in the sprint, team sprint and keirin.
Pendleton defended her sprint title in style on Saturday, having teamed up with Shanaze Reade to defend their team sprint crown, to add to Britain's record haul of medals which has now totalled 11.
At the end of the championships Britain have nine gold and two silver.
