Great Britain enjoyed a successful day with six medals including three golds on day three of the UCI Para-cycling Track World Championships in Los Angeles.
Sophie Thornhill and pilot Corrine Hall won a second world title of the week as Britain secured a 1-2-3 in the tandem time trial.
Jon Gildea won a maiden world title in the C5 individual pursuit, while James Ball and pilot Matt Rotherham landed gold in the tandem 1km time trial ahead of Neil Fachie and Craig Maclean.
Thornhill and Hall were last to go and their time of one minute 09.552 seconds pushed Aileen McGlynn and Louise Haston's time of 1:11.089 into silver.
Alison Patrick and Helen Scott claimed bronze with a time of 1:11.115.
Thornhill said: "(I'm) really happy! It's an odd one, Corrine's not a sprinter and we've been primarily working on the pursuit, so to come away with the kilo is brilliant."
Gildea, who won silver in the 1km time trial on Friday, won the first rainbow stripes of his career with a super second half of the race to cross the line in a time of 4:36.509 to beat Brazil's Lauro Cesar Chaman by over two seconds.
Gildea said: "It means a big deal. It seemed like a big challenge to achieve. To think about doing this was a big challenge, it seemed like a worthy goal to get my teeth into. I'm really happy."
Ball and Rotherham were just over a second outside of Fachie and Pete Mitchell's world record with a time of 1:00.727 as they were the eighth of nine pairs on the track.
Fachie and new pilot Maclean were last on track but could not beat them and had to settle for silver in a time of 1:02.039.
Ball said: "We've only been training together since January, so I'll take that!"
