The bike, a custom edition Pinarello Dogma 65.1, complete with Team Sky branding and a "Wiggins" name sticker on the top tube, is being advertised for sale at £7,500 ($10,250/€8,750)

Sir Bradley rode the bike in the final stage of the Tour, a 120 kilometres ceremonial leg from Rambouillet to Champs-Élysées in Paris, as he beat Team Sky team mate Chris Froome by more than three minutes.

It is being advertised on the social media network by British coaching company trainSharp, a brand with close ties to Team Sky through the team's former directeur sportif, Sean Yates, who joined the company as a coach in 2014.

It remains unconfirmed whether the company owns the bike, or indeed whether the bike is being sold on behalf of Sir Bradley himself.

As well as its special edition yellow paintwork, the bike is also given a matching yellow Fizik saddle and bar tape, as well as yellow Speedplay pedals, and even yellow decals on his Shimano Dura-Ace C35 wheels.

The bike is fitted with Shimano's top-tier groupset from the time, the 10-speed Dura-Ace Di2 groupset - the first iteration of Di2, complete with an external battery which can be seen hidden behind the chainrings.

trainSharp is also offering for sale at £5,000 (£7,000/€6,000) an Eddy Merckx bike ridden by Lance Armstrong, winner of seven consecutive Tour de France titles between 1998 and 2005 before he was stripped of all his victories for doping.

A few weeks after claiming victory in the Tour de France, Sir Bradley won the Olympic gold medal in the time trial at London 2012.

Some of the gloss of Sir Bradley’s Tour de France victory has also been taken off following accusations that he used performance-enhancing drugs under the guise of treating a legitimate medical condition to win the race.

A report published in 2018 by the House of Commons Digital, Culture, Media and Sport Committee claimed that a powerful corticosteroid was administered to Sir Bradley by Team Sky under the disguise of a therapeutic use exemption (TUE).

The allegations had first emerged in 2016 shortly after Sir Bradley won the fifth Olympic gold medal of his career at Rio 2016 when the Russian Fancy Bear hacking into the database of the World Anti-Doping Agency and their publication of TUE certificates

Sir Bradley and Team Sky - who now compete under the name Ineos Grenadiers - have continued to deny that any drugs were used without medical need.
