Nairo Quintana is feeling in confident mood ahead of the Tour de France after a stunning victory on stage seven of the Tour de Suisse on Friday.

Quintana is again seen as yellow jersey contender in France, the Colombian having tailored his 2018 campaign to ensure he is ready for the opening stage on July 7.

Tour de France success is the only thing missing from Quintana's palmares after winning the Giro d'Italia in 2014 and Vuelta a Espana two years later.

He missed this year's Giro as Chris Froome completed cycling's triple crown, something Quintana will hope to achieve next month.

And Movistar's top rider looked in fine fettle on Friday with a superb solo break to take the stage win on the summit finish in Atzmannig.

"I wanted to see how my physical condition was and fortunately I felt good. The work of the team was really good with all of us pushing right from the start," Quintana said.

"It is important for your own body, and for the team, to know that you are going well ahead of the Tour.

"We wanted a make it a big test and on Sunday we will have another. We will have to ride strong on the flat, defend ourselves and do the best that we can.

"These nine days of competition give us more time to spin [the legs] and I believe that it will give us more luck for July."

Quintana's triumph saw him take a large chunk out of general classification leader Richie Porte, the pair now only separated by 17 seconds with two stages remaining.
