Rigoberto Uran is targeting glory in the Tour de France after re-signing with Cannondale-Drapac for another three years.
The Colombian finished as runner-up in the 2017 Tour, 54 seconds behind four-time champion Chris Froome.
Uran claimed one stage victory during the race - something Froome did not manage - but the 30-year-old has the yellow jersey firmly in his sights after his new deal was announced on Monday.
"I'm very happy with the team," he said. "The environment here suits me. I have a lot of respect for the people that are part of the team - the mechanics, the soigneurs, the staff, my team-mates.
"They know how to have fun off the bike and be serious when it's time to race. That's important to me.
"A three-year contract offers security, and the team is willing to allow me to focus my season on the Tour de France. I was very happy to sign.
"I'll race many races, and I have many goals. The biggest, of course, is the Tour de France. I want to win the Tour."
Slipstream Sports CEO Jonathan Vaughters said: "We're fully prepared to support Uran in this pursuit.
"His ambition is one that we share, and the team is excited to work with him on his biggest goal. Rigo is a great mentor and leader. Good times and bad, he inspires people."
