Bobridge has enjoyed success both on the road and track throughout the duration of his career, which has seen him earn 17 Olympic, Commonwealth and World Championship medals.

His two Olympic medals came in the men’s team pursuit at both London 2012 and Rio 2016, where Australia ended as the runner-up to Britain on both occasions.

The Australian claimed a gold medal in the discipline at the 2010 and 2011 World Championships.

The Adelaide-born cyclist also secure the individual pursuit title in the latter event.

Bobridge also boasts four Commonwealth Games gold medals having won the individual and team pursuit at Delhi 2010, before defending his titles four years later in Glasgow.

Bobridge is convinced he has taken the right decision.

"I have had a lot of questions myself over the past months, but to finally tell people, there was a bit of relief," he told Cycling Australia.

"But at the same time, it was a hard decision as well.

"There is a lot of unknown about the next chapter, of course a little hard to walk away.

"But I know deep down I have made the right decision.

"Definitely have no regrets and am ready to start the next chapter."

Bobridge ends his career as the current world record holder in the individual pursuit after setting a time of 4min 10.53sec at the Sydney Velodrome in 2011.

He also competed at four editions of the Giro d’Italia and fell narrowly short of breaking the International Cycling Union (UCI) hour record in 2015, becoming one of the first to attempt the event under its current format.
