Olympics : Wiggins time trial bike

This is the bike that Bradley Wiggins rode in the Tour de France time trial stages, including the now infamous Stage 19 that secured him victory in the tour. The Pinarello Dogma 2 comes at a cost of £10,000, clearly not your average road bike! The frame is made entirely from carbon fibre, the gearing system is electronic and the bike itself weighs in at just 7kg. Wiggins adds his own personal touches to the bike to suit his riding style, most notably the o.symmetric chainring aimed to maximise his pedalling efficiency.

On Wednesday Wiggins will put this bike to the test in the Olympic time trial, hoping to beat Cancellara and Froome to the gold medal
