Graham Fredericks has stepped down as chief executive of Cycling Australia, the sport's domestic governing body, after 18 years in the role.
Fredericks' last act will be to oversee the Cycling Australia annual general meeting on November 9.
Cycling Australia is already on the hunt for a new president, following Klaus Mueller's resignation in August.
Fredericks said: "It has been a very real privilege to be at the centre of cycling's growth and development in Australia over the past two decades. However, all good things must come to an end and I believe the time is right to step aside and allow for a fresh approach.
"I am very proud of the role I have played in the sport's growth in popularity and profile as well as the expansion of Cycling Australia as an organisation. Cycling in Australia is on the verge of another significant step forward as an integrated industry. While I have been very active player in this process, it is important that I recognise when it is time to allow new energy and enthusiasm to drive this strategy."
Cycling Australia said a nominations committee has been working to draw up a shortlist of candidates for the vacant Cycling Australia presidency, and that once appointed, the new president "will play an active role in the recruitment of the new CEO."
