Great Britain won bronze medals in the men's and women's team sprint on the opening day of the Track Cycling World Cup in Guadalajara, Mexico.
The men's trio of John Paul, Callum Skinner and Lewis Oliva booked their place in the bronze final by qualifying fourth fastest and were then awarded the medal after their French opponents were relegated for an illegal changeover. The Netherlands beat Germany to gold.
The women's duo of Victoria Williamson and Danielle Khan followed suit by qualifying third fastest and then beating the French pairing of Sandie Clair and Olivia Montauban in the bronze-medal final. Trade team Max Success Pro Cycling defeated Russia to claim gold.
The British team's most senior member, Dani King, made a lone breakaway in the women's scratch race, but eventually finished 14th.
In the men's team pursuit, a youthful British quartet made up of Jon Dibben, Jacob Ragan, Oliver Wood and Chris Latham finished 13th, as Switzerland claimed gold ahead of Australia.
Ragan returned action later in the day to finish 12th in the men's points race. Russia's Kirill Sveshnikov won gold.
The three-day meeting, which is the third and final world cup of the season, continues on Saturday with the women's sprint, men's keirin, women's 500m time trial, men's individual pursuit, men's omnium and women's omnium. The event concludes on Sunday.
