Italy's Filippo Ganna smashed the men's 4km individual pursuit world record to win gold on the final day of the Track Cycling World Cup in Minsk.
Having beaten the previous mark by American Ashton Lambie in qualifying, Ganna took more than a second off the record again in the final.
Ganna clocked four minutes 2.647 seconds to easily beat Britain's John Archibald, while Lambie took bronze.
Britain's Laura Kenny claimed bronze in the women's omnium on Sunday.
It was a second medal of the meeting for the four-time Olympic gold medallist after she won silver alongside Emily Nelson in the madison on Saturday.
