Simon Gerrans will leave Team Sky at the end of the season after signing for new Australia outfit GreenEdge.

Gerrans, who won the Tour of Denmark earlier this month, is the only Australian to have won stages in all three Grand Tours but, after top-ten finishes in this year’s Amstel Gold Race, Fleche Wallonne and Liege-Bastogne-Liege , will now turn his attention to the trio of Ardennes Classics.

“I’ve always targeted the Ardennes Classics and after finishing third at the Amstel Gold Race this year I’m looking forward to preparing specifically for these races again with the backing of GreenEdge,” said Gerrans.

“To win Amstel Gold Race, Fleche Wallone or Liege-Bastonge-Liege would be something special. I know everything would have to go absolutely right for me to be able to achieve that and I’m doing everything I can to give myself the best chance.”

Gerrans is an old hand at joining new teams after riding for both Cervelo TestTeam and Team Sky through their debut seasons and the 31-year-old was quick to pay tribute to his current team.

“I’ve had a really good two-years at Sky and it’s been a privilege to ride with a team that has set the benchmark on professionalism,” he added. “I’m looking forward to riding the rest of this season with Sky and have appreciated the team’s understanding in why I made the decision to join a new Australian team.”

Gerrans joins fellow Australians Stuart O’Grady, Jack Bobridge, and Cameron and Travis Meyer at GreenEdge, who are hoping to secure a WorldTour license for 2012, while Dutch duo Pieter Weening and Sebastian Langeveld, and Eritrean Daniel Teklehaymanot have also signed to date.
