Great Britain win six World Para-Cycling medals
Great Britain collected six medals - two golds, three silvers and a bronze - on day two of the Para-Cycling Track World Championships in Los Angeles.
Mark Colbourne won the C1 3km pursuit ahead despite a protest from Germany.
Anthony Kappes, piloted by Craig MacLean, beat fellow Brits Neil Fachie and Barney Storey in the B kilo.
Darren Kenny won C3 3km pursuit silver, Aileen McGlynn and Helen Scott took silver in the kilo, and Jody Cundy won bronze in the C4 4km pursuit.
Colbourne faced reclassification halfway through the competition after Germany claimed he should race in a less disabled category, but the UCI, the governing body, rejected their protest.
"I don't think it's sunk in yet to be honest," he said of becoming world champion. "Today certainly means a heck of a lot to me.
"Since first stepping on the bike two years ago I've had this dream. Big thanks to my coach Tom Stanton for getting me to possibly the best year of my life."
In the tandem pairings, defending champion Fachie lost his title to Kappes by just 0.099 of a second.
Kappes said: "It was a close race last year when Craig was riding with Neil and it was very similar. Our win was marginal."
Racing continues on Sunday with five GB riders competing in the 1km time trial and Sarah Storey - 500m time trial gold medallist - in the pursuit.
