The 18-year-old was scheduled to contest the madison at the world championships in Kazakhstan but came off his bike while riding to the Astana velodrome.

Cycling Australia and Tasmanian Institute of Sport coach Matt Gilmore described the accident, which left Robinson with an injured wrist, as extremely unfortunate.

Fresh from claiming a silver medal in the omnium, South Australian Rohan Wight took Robinson's place alongside Victorian Kelland O'Brien and the pair went on to add another gold to the one they claimed with the Tasmanian in the team pursuit.

The Australian pair took a solo lap at the event's midway point to set up the victory sealed by also winning the final sprint.

Robinson had earlier finished 10th in the individual pursuit.

With Australia's 12 medals (four gold, five silver and three bronze) the most of any nation — a feat the nation also achieved at the senior world titles in Paris — the championships extended an impressive record for Gilmore.

Legana's former madison world champion coached Annette Edmondson and Danielle McKinnirey to world championship gold medals this year and fellow South Australians Glenn O'Shea and Wight to silvers.
