Defending champions Britain avoided an embarrassing exit in the team sprint event before a re-start in the qualifying session earned them the fastest time at the Olympics.
First man Philip Hindes, who seemed in trouble with his front wheel, crashed after a quarter of a lap in their qualifying match against Germany but Britain were allowed to re-start according to International Cycling Union (UCI) regulations.
Hindes this time took a cannonball start to perfectly launch Jason Kenny with quadruple Olympic champion Chris Hoy finishing it off in style in Olympic record time.
France clocked the second fastest time ahead of Australia and Russia, with world champions Germany taking a disappointing fifth place.
Germany face Russia in the first round for a place in the gold medal or bronze medal final.
Britain will take on Japan, France will face New Zealand and Australia meet China.
