Matthew Richardson, Harry Ledingham-Horn and Harry Radford set a new British record on their way to gold in the men's team sprint at the UCI Track Nations Cup in Turkey.
Having been the fastest in qualifying, the British trio posted a record time of 41.788 seconds in the first round, before Ledingham-Horn reversed a narrow deficit against Japan in the gold-medal ride.
"We worked really well as a team to glue it together," said Richardson, who was competing with the GB squad for the first time since switching nationality from Australia.
"It was the first time we had ever raced as a team so we were learning every single ride and trying to take as much as we could from the one before."
Meanwhile, Lowri Thomas, Lauren Bell and Rhian Edmunds took silver for Britain in the women's team sprint, with the Netherlands proving too strong in the final race.
