The two-time Herald Sun Tour stage winner, who also rode the Tour de France in 2012, passed away overnight on Tuesday, prompting a string of tributes from some of the country’s top riders including Anna Meares.
Cantwell retired from professional cycling in 2014 when he was riding with Australian pro continental team Drapac as a road sprinter. That year he rode the Tour Down Under, Herald Sun Tour and raced in Asia and the US.
Prior to that he had spent two seasons on the WorldTour with Saxo-Tinkoff and in 2011 was the Australian criterium national champion.
Jonathan Cantwell has died aged 36.
After finishing cycling Cantwell turned to triathlon and represented Australia at the age group world championships on the Gold Coast in September.
Last year Cantwell revealed he had undergone successful surgery and chemotherapy for testicular cancer.
He had also worked as chief executive with bicycle manufacturer Swift Carbon Australia post professional cycling.
