Tacks on road wreak havoc on Mur de Peguere
Ned Boulting and the team investigate the carpet tacks that wreaked havoc on Stage 14.
Champion Cadel Evans punctured at the top of the final climb, and had to wait more than a minute for a spare wheel so he could rejoin the chase.
As many as 28 carpet tacks were found on the road, while Team Sky's race leader Bradley Wiggins neutralised the race, allowing his rival Evans to catch up.
