"The team starts in Mont-Saint-Michel with the aim of winning a stage and delivering a strong general classification," Technical Director Nico Verhoeven said of the team's aim for the Tour which begins on July 2.
Verhoeven added that the final selection will be made following three upcoming races.
"Several riders have trained at altitude in Tenerife. Their last preparations will be done in three stage races, the Tour de Suisse, the Criterium du Dauphiné and the Ster ZLM Toer. Several days before the national championships the final nine riders will be announced."
