Wiggins rage as broken bike costs Brit a medal

BRITAIN&rsquo;S Bradley Wiggins&rsquo; crusade for a medal was cruelly ended by a mechanical failure in the closing stages of the Road Cycling World Championships time trial in Mendrisio, Switzerland. <br /><br />Wiggins, a six-time world champion on the track, was third on the final climb of the three-lap circuit when he was forced to change his bike &ndash; and the 29-year-old ended up finishing 21st. <br /><br />Switzerland&rsquo;s Fabian Cancellara cruised to victory, equalling Michael Rogers&rsquo; event record of three wins in the process. Sweden&rsquo;s Gustav Larsson came second, with Germany&rsquo;s Tony Martin two and a half minutes behind to finish third. Christopher Froome, another British rider, came 18th.<br /><br />Reigning Olympic champion Cancellara clocked an impressive time of 57 minutes, 55.74 seconds over the 49.8km course. <br /><br />Wiggins was well placed to take bronze until, in the last 10km, the front derailleur of his bike malfunctioned and its electronic gear-change system consequently failed. The Londoner was visibly livid, climbing off his bike and hurling it to the ground in disgust.<br /><br />Cancellara will be gunning for more glory in Sunday&rsquo;s men&rsquo;s road race. in which David Millar will lead Britain&rsquo;s nine-man squad.
