Vicky Pendleton and Chris Hoy added two more gold medals to Great Britain's impressive tally on the final day of the World Track Cycling Championships.
Hoy has now won four world titles in the four-lap event
Hoy took his third medal of the championships and second gold with victory in the kilometre time trial.
And Pendleton made it a personal hat-trick of golds in the women's keirin after earlier wins in the individual and team sprints.
Team GB easily topped the medals table with 11 in all, seven of them gold.
Pendleton kept her nerve in the keirin after there were two false starts in the final.
The first false start came when Christin Muche barged into Pendleton, for which the German rider was disqualified.
When the race did get under way, Pendleton sat back in the field for most of the race before powering away from her rivals on the final lap.
I knew this was my last competitive kilo so to finish on a high was what I had dreamed of
China's Shuang Guo took silver with sprint champion Anna Meares of Australia in bronze.
"I can't believe it," said Pendleton. "Let's face it, in this team a world medal is average, but three golds is a little bit special."
Hoy finished in a time of one minute, 00.999 seconds to win the kilo, which brought him an Olympic title in Athens in 2004.
Hoy had already won keirin gold and a silver in the team sprint this week.
Francois Pervis of France took silver, nearly a second adrift, while Britain's Jamie Staff won bronze.
"I knew this was my last competitive kilo so to finish on a high was what I had dreamed of," said Hoy. "I felt strong right until the end even though I faded a little bit in the last half.
"I'm delighted. I didn't know what sort of performance I would put in, but this is way better than I expected.
"If I had gone three thousandths of a second quicker in the team sprint it would have been the world championships of my dreams, but apart from that it has been perfect."
Staff, a former sprint and keirin specialist, stunned the kilometre specialists when he started second from the field of 20 riders to set the early pace of one minute 02.074 secs.
His mark stood until pre-race gold medal contender Pervis hit full power in the second half of his effort to grab provisional top spot.
With Staff assured of the bronze, Hoy hit a big gear from the outset and led Pervis at every stage of the race.
Britain now have six golds this week and 10 medals in total.
Craig MacLean narrowly missed out on a medal in the men's sprint, losing out to France's Mickael Bourgain in the bronze medal race.
Bourgain took the best-of-three result 2-0.
The gold went to Dutchman Theo Bos, who beat Gregory Bauge of France also in two straight races.
Swiss pair Franco Marvulli and Bruno Risi snatched victory in the madison by gaining two points in the final sprint to finish one point ahead of Dutch duo Peter Schep and Danny Stam.
The Swiss also won the title in 2003 and finished second in 2004.
Alois Kankovsky and Petr Lazar of the Czech Republic took the bronze.
Australia's Katherine Bates took gold in the women's points race with a winning total of 35 points.
Mie Bekker Lacota of Denmark took the silver medal on 29 while New Zealand's Catherine Cheatley finished third on 27 to take the bronze.
