Great Britain's bid for a sixth women's team pursuit Track Cycling World Championships title at a seventh attempt began in supreme fashion on day two in Cali, Colombia.
Unlike the men's squad, who finished a woeful eighth on day one, the British quartet of Joanna Rowsell, Laura Trott, Katie Archibald and Elinor Barker advanced as fastest qualifiers.
Britain won five of six world titles in the event over three kilometres and with three riders - silver in 2010 the only blot on the record - and their dominance shows little sign of abating with the addition of an extra kilometre and an extra rider this season.
The world record holders finished in four minutes 28.597 seconds to set up a gold medal ride-off with Canada's Laura Brown, Jasmin Glaesser, Allison Beveridge and Stephanie Roorda, who finished in 4mins 30.721secs.
The bronze will be contested by Australia and Poland.
Defending champion Jason Kenny advanced in supreme fashion in the men's Keirin, which begins behind a Derny bike.
The 25-year-old from Bolton swerved to avoid a pile-up on the penultimate lap before catching and overtaking Matthew Glaetzer of Australia to win by half a wheel and progress to the semi-final at the first time of asking.
Matt Crampton and Kian Emadi fell into the repechages after failing to win their heats.
Two advanced from the second-chance saloon and Crampton won ahead of Awang Azizulhasni of Malaysia to progress.
Emadi finished third behind Glaetzer in his repechage heat to be eliminated.
Ireland's Ryan Mullen was fourth-fastest in individual pursuit qualifying, clocking 4:22.419 to advance to the ride-off for bronze, where he will race New Zealand's Marc Ryan, who finished in 4:21.865.
Mullen's fellow Irishman Martyn Irvine finished 12th in 4:26.525 and Briton Owain Doull was 15th of the 20 riders in 4:28.193.
