Great Britain's Jason Kenny set an Olympic record in qualifying fastest in the men's sprint on day three of competition at the London 2012 velodrome to advance to the second round with a first-round bye.
The 24-year-old from Bolton was selected ahead of Sir Chris Hoy, the 2008 Olympic champion in the event, after the International Olympic Committee and International Cycling Union limited the number of riders in individual events to one rider per nation.
Kenny, who won silver in China aged 20, clocked 9.713 seconds, improving the mark of 9.815secs Hoy set en route to gold four years ago, in the ranking round. The result saw Kenny claim top seeding and, with 17 riders entered, the Briton skipped a phase of the gruelling three-day competition.
World champion Gregory Bauge of France was second quickest in 9.952, with Australia's Shane Perkins third in 9.987 and Germany's Robert Forstemann fourth in 10.072.
There was misfortune for Spain's Hodei Mazquiaran Uria, who required a second ride after his saddle disintegrated on the flying lap of his third attempt.
He finished in 10.604 and was set to face Perkins in the first round, with Bauge poised to ride against Zafeirios Volikakis of Greece.
In the first of six disciplines in the omnium, Ed Clancy, fresh from claiming team pursuit gold on day two, finished first.
Clancy clocked 12.556 in the flying lap, more than half a second clear of the field.
Shane Archbold of New Zealand was second in 13.112, with world champion Glenn O'Shea of Australia third in 13.222.
Ireland's Martyn Irvine finished in 13.504, placing ninth with five events remaining in the two-day competition.
