According to a team spokesman, the contract extension is another step towards helping Dumoulin reach his full potential at the highest level of the sport.

The 24-year-old Dutch time trial specialist had a breakthrough season in 2014, confirming his status as one of the fastest riders against the clock in the professional road cycling peloton. His results included a victory at the Dutch time trial championships, a stage win in the Eneco Tour and finally a bronze medal at the World Championships time trial in September.

Commenting on his new contract, Dumoulin told Roadcycling.com "I am really happy for the mutual confidence and trust with the team that allowed us to open up my contact and extend it. I feel at home in this team as I can develop myself together with the team to my full potential. I have ambitions to work with this team for a longer period and to keep challenging ourselves together."

Team Giant-Alpecin General Manager Iwan Spekenbrink explained "We are in the process of building a performance project around Tom. It was obvious for us to keep him on board and to keep developing him to a great rider in the WorldTour, and to allow him to reach his full potential not just in time trials but also as a general classification contender."

Dumoulin will start his 2015 season at the Tour Down Under later this month, before continuing to build up for his season objectives that include taking part in the Tour de France where he hopes to line-up as a contender for the opening time trial stage on home soil in The Netherlands.
