Dylan Groenewegen has officially announced a four-year contract extension with Jumbo-Visma. With 15 wins this year, the 26-year-old Dutchman has become one of the peloton's top sprinters and is confident he will get even faster.

"I am now 26 years old and still going strong," Groenewegen said in a team press release. 'I joined the team when I was 22. Since then I have improved a lot. This has happened to every rider who joined the team."

Groenewegen turned pro in 2012 with Continental Cycling Team De Reike, where he spent three years before moving to the Professional Continental team Roompot-Oranier.

He made his first attempt at the WorldTour in 2016 with Lotto NL-Jumbo and stayed with the team after moving to Jumbo-Visma. Over the past four years, he has become one of the top sprinters on the WorldTour with four stage wins in the Tour de France. He has also won five times in both the Tour of Britain and Tour of Norway, and three times in Paris-Nice. In one-day races, he has had success in the Cune Brussel Cune and the Drydergues Bruges des Pannes.

"Starting from scratch, let's see how it goes now. 'This team is doing very well. This team is doing very well. If I point out something that needs to be improved, it's looked at and everyone on the team starts working on it. That's what made me decide to stay."

Jumbo Visma has transformed into one of the winningest teams on the World Tour. Over the past four years, the team has gone from 19 wins in 2016 to 26 in 2017, 33 in 2018, and 51 this year.

The team's success this year is largely due to the work of Groenewegen, Primoz Roglic, Mike Tunissen, and Wout Van Art. Also winning were Jonas Wingeard, Lawrence de Plas, Tony Martin, Jansen Amund Grondahl, Sepp Kuss, Antoine Torhoek, and Jos van Emden.

Jumbo Visma's standout performance came at the Tour de France, where Tunissen won the opening stage and took the first yellow jersey. The team also won the team time trial on stage 2, with Groenewegen winning stage 7 and Van Aert on stage 10.

In the Vuelta a España, Roglic took the overall win.

Groenewegen attributed the team's success in part to the management's ability to accept rider feedback and equipment development. He attributed part of his own success to the support from a strong lead-out team and the trust that has been built with Jumbo-Visma over the past four years.

"Everything is taken into account to make sure we sprint as fast as possible," he said. This is getting better every year. Of course, I'm looking at other teams, but I'm really comfortable here. We have reached a good agreement. I have what I want here. So why change teams?

"Mutual trust is very important. I feel that the team trusts me and I think they feel that I trust them. The players around me are doing very well. If you look at this year, you can see that I have a super train around me. By staying here, I will be able to continue to grow. I want to challenge myself with the team."
