Manchester-based cyclists Victoria Pendleton and Jess Varnish were relegated from the women's team sprint at the London 2012 Olympics, leaving an expectant home crowd stunned.
The pair broke the world record in qualifying, before China lowered it further and were second fastest in the semi-finals to book their place in the gold medal showdown.
But the commissaries ruled that Pendleton had overtaken Varnish outside the stipulated area on their final lap and after a heated discussion with British coach Dave Brailsford, trackside judges decided to disqualify the pair.
It's not the first time British cyclists have fallen foul of the rules in recent competitions. At the World Championships in Melbourne earlier this year Philip Hindes, Jason Kenny and Sir Chris Hoy were disqualified in a similar incident.
