Great Britain’s Matt Crampton sprinted to keirin gold as the second round of the UCI Track Cycling World Cup in Mexico concluded.
The 27-year-old, a European champion in the discipline in 2011, beat Germany’s Tobias Wächter to the line by less than four-hundredths of a second with Australian Shane Perkins third in Aguascalientes.
Crampton tweeted: "Chuffed with the Keirin win! Thanks for all the support everyone."
Laura Trott added silver in the omnium, behind world champion Sarah Hammer, as Great Britain finished third in the medal standings behind second-place Australia and leaders Germany.
London Olympian Jess Varnish narrowly missed out on bronze in the sprint, losing to Hong Kong’s Wai Sze Lee with world champion Becky James seventh. In the Madison, the pairing of Owain Doull and Jon Dibben, like Varnish, also finished fourth.
Kian Emadi took sixth with a new personal best in the kilo as France’s Francois Pervis set his second world record at the meeting, a staggering time of 56.303 taking two seconds off the previous best.
Having been part of the silver medal-winning trio in the team sprint with Jason Kenny and Philip Hindes, Crampton was seeking another podium spot having exited at the qualifying stages of the individual sprint on day two.
Drawn in heat four, Crampton avoided the repechages with second place behind Perkins.
Victory in the second round, in a heat which included Azizulhasni Awang, ensured a spot in the final. Briton Lewis Oliva, riding for Team USN, was unable to join Crampton in the major final after finishing fourth in the second heat.
And in the final, Crampton produced another fine performance to continue Britain’s gold medal run at the meeting. Oliva took tenth place after the minor final.
After a mixed first day in the women’s omnium, double Olympic champion Trott had entered day two in second overall but third in the individual pursuit and tenth in the scratch race left the 21-year-old in the bronze medal position with leader Hammer unassailable in the gold medal spot.
But second in the final discipline, the 500m time trial, saw the double gold medallist at the Manchester UCI Track Cycling World Cup climb to second and take her first medal of the event after missing the team pursuit.
The high altitude of the Aguascalientes track had seen numerous world records tumble and the women’s sprint continued the pattern.
Germany’s Kristina Vogel, who had dominated the women’s sprint disciplines in the world cup series so far, set a ferocious pace in qualifying with a new record of 10.384 seconds.
Welshwoman James was third fastest in 10.627 with Varnish fifth in 10.662. Both progressed through the 1/8 finals before James was forced into the 5th-8th place minor final after losing in straight heats to Wai Sze Lee.
Varnish saw off the challenge of the Netherlands’ Elis Ligtlee but came undone against an inspired Vogel, who went on to the win gold against Olympic champion Anna Meares.
And Varnish, 23, was unable to defeat Lee in the bronze medal ride as James took seventh from the minor final.
Doull and Dibben, both part of the team pursuit squad which won bronze, were able to win two of the eight sprints in the Madison. But two laps down to eventual winners Spain and a lap down to second place Belgium, the duo were competing for bronze against Russia.
Despite taking the final sprint, three points for Russia was enough for a total of 12 points ahead of Britain’s 10.
The final round of the 2013-14 UCI Track Cycling World Cup takes place in Mexico, in Guadalajara, from 17-19 January 2014, as the Great Britain Cycling Team continues the journey to next February's world championships in Cali, Colombia.
