Mark Cavendish and Bradley Wiggins conjure madison magic
Mark Cavendish combined with Sir Bradley Wiggins to win the madison in the first round of the Revolution Series at the Derby Arena.
The British pair defeated Kenny de Ketele and Moreno de Pauw, of Belgium, by 11 points. The event marked 30-year-old Cavendish's return to track cycling.
Cavendish had earlier finished in second place, behind team-mate Ed Clancy, in the omnium.
The track event was Cavendish's first since the 2008 Olympics; he hopes to qualify for Rio 2016 as part of Great Britain's team.
Clancy beat Cavendish by 18 points, while fellow Briton Chris Latham finished third on the second day of the series.
Team GB can use only one rider per track discipline at the Olympics. Qualification began at the Revolution Series and continues in Manchester in October before further meets, during November, in London and Glasgow.
Clancy, like Cavendish, represented Team GB at London 2012, and won bronze in the omnium.
Laura Trott, who won gold in the same event, also impressed this weekend by beating Jolien D'Hoore into second place by three points.
Trott (23), the world champion, finished second to the Belgian during Sunday's final points race but earned victory overall.
Wiggins (35), was earlier fined 200 Swiss Francs (£130) by race organisers for failing to attend the presentation after helping GB win gold in the team pursuit on Friday.
Jason Kenny, Trott's fiance, beat fellow Briton Philip Hindes to gold in the keirin.
The first round of the Revolution Series marks the start of qualifying for the Rio Olympics, offering points for riders to enter the three World Cup events in October, December and January.
