Sport Director Gabriel Rasch will be calling the shots from the team car in France and confirmed that Henao and Poels will both lead the team.
He said: “They will be joint leaders and I think we have a good chance. Wout is hungry for some results for himself and obviously Sergio won it last year.
“Going from eight-man teams to seven, I think it’s good to have more options. We had a debate about how many flat guys to take and this is what we came down to.”
The climbs are grouped towards the back end of the race, but Rasch is warning against crosswinds on day two.
He continued: “The second stage is flat, heading south all day, so depending on the wind it could be a wild day, like last year.
“The guys will get their first taste of the climbs on stage three and then there’s a hilly time trial on stage four. Stage five has a pretty hard final lap around Sisteron, with narrow short climbs, and the last three stages, six, seven and eight, are all tough. The last day is pretty similar to previous years too - short, but hard around Nice and Monaco.”
