Stage four at Tour Down Under took riders along a 129.2 kilometre route between Unley and Campbelltown, with the infamous Corkscrew climb positioned just 5.7 kilometres before a fast descent to the line. Early in the race a six man group went clear, with the remaining three caught shortly after hitting the Corkscrew road.
Whilst the action was brewing at the front, Team Sunweb hit trouble in the peloton with GC-leader Chris Hamilton requiring a bike change just before the final climb.
Still with good legs, Chris attempted to bridge across to a four-man move that tried to go clear on the climb, but it all came back together and a group of 20 riders sprinted for the win.
After finishing in 9th place, Chris moves up to 4th in the GC and takes over the young riders jersey from team mate Michael Storer. Jai Hindley also finished the stage in a good position, rolling across the line 13th.
