Great Britain's Anthony Kappes and Craig MacLean bounced back from disappointment with a blistering world record in qualification for the men's tandem sprint at the London 2012 Paralympic Games velodrome.
Kappes and MacLean had mechanical trouble at the start and did not finish the one-kilometre time-trial on day three as Neil Fachie and Barney Storey won gold in a world record time.
But on Sunday morning it was the turn of Kappes and MacLean to take their event to new margins, clocking 10.050 seconds over the flying 200metres to qualify fastest of the seven teams for the knockout phase.
Due to the number of teams in the event, Kappes and MacLean received a bye to the semi-finals, skipping the best-of-three quarter-finals.
Fachie and Storey joined Kappes and MacLean in the last four with a comfortable 2-0 quarter-final win over Argentina's Alberto Nattkemper and Jonatan Ithurrart.
In the women's blind and visually impaired three-kilometres tandem pursuit, Aileen McGlynn and Helen Scott will meet fellow Britons Lora Turnham and Fiona Duncan in the race for bronze.
McGlynn and her pilot Scott clocked three minutes 36.930 seconds in qualification, with Turnham and her pilot Duncan finishing in 3mins 37.085secs.
World champions Catherine Walsh and Francine Meehan of Ireland clocked 3:36.453 to advance to the race for gold in second place behind New Zealand's Phillipa Gray and Laura Thompson, who set a world record of 3:31.530.
Ireland's Katie Dunlevy and Sandra Fitzgerald finished in 3:42.445, placing fifth.
