Great Britain's women's team pursuit quartet blazed to yet another world record at the track cycling World Cup in Aguascalientes.
Since the event was expanded to four riders and increased to 4000m this season, Great Britain have lowered the world mark with almost every appearance on the track.
They erased their time from the recent World Cup in Manchester in qualifying and then went quicker again in the final.
The quartet of Katie Archibald, Elinor Barker, Dani King and Jo Rowsell clocked 4:16.552 to finish nearly seven seconds quicker than second placed Canada.
Olympic team sprint champions Philip Hindes and Jason Kenny combined with Matthew Crampton to take second in the men's team sprint, losing out by fractions to Germany.
And Germany also bettered Great Britain's Jess Varnish and Becky James in the women's team sprint final.
Elsewhere, Owain Doull, Steven Burke, Jonathan Dibben and Sam Harrison took bronze in the men's pursuit with a commanding win over New Zealand, while Australia were confident winners over Denmark in the gold medal race.
And double Olympic champion Clancy is ranked 11th after three rounds of the men's omnium.
