GB cyclists 'building momentum' for 2012 - Brailsford

David Brailsford, British Cycling's performance director, praises Team GB's performance at the Track World Cup in London, saying the squad are "building momentum" in the build-up to London 2012 after topping the medals table with four golds, one silver and two bronzes.

Brailsford believes Sir Chris Hoy is "back to his best" after winning two gold medals, and that the British riders have benefited "more than other nations" from the opportunity to compete in a world-class competition at the Olympic Velodrome.
