Former world champion Tom Dumoulin, second to Geraint Thomas in the 2018 Tour de France, is quitting Sunweb after eight years, the Dutch team announced Monday.

"After an incredible eight-year journey filled with countless successes, Team Sunweb and Tom Dumoulin are set to go their separate ways at the end of the 2019 season," Sunweb said.

The 28-year-old Dutchman, who was forced to sit out this year's Tour de France with a knee injury, had two years to run on his Sunweb contract. "After the disappointment of missing the Tour and finding myself sitting at home, I started to consider that a new environment could be refreshing," he said on the team website. "There were great offers and this phase of my career felt like the right time to take it."
