The Ballarat cyclist took a tumble inside the last 3km of the 128.8km stage as riders were setting up for a sprint finish.

His father Gerard White said Nick had a sore arm, but had told him did not expect it to be an issue for the remainder of the under-23 event.

The 21-year-old was classified 129th - 52 seconds down with the bulk of the 154 riders to finish the stage.

Denmark's Norsgaard Jorgensen rode solo to the line to take the honours by the 52-second margin.

Great British Ethan Hayter and Tom Pidcock joined him on the podium.

Kaden Groves was the first of the Australian team to finish in seventh.

He was followed by teammates Alex Evans 44th, Liam Magennis 66th, Michael Potter 98th, Sam Jenner 102nd and White - all in the same bunch.
