Wiggins and Evans have taken victory in the six-day Swiss event in the past two years and gone on to win the Tour de France that year.
With Wiggins preparing for the Giro d’Italia, Froome will lead Team Sky at the event which begins with a 7.45km time trial on Tuesday and ends with an 18.6km stage against the clock on Sunday.
There are no summit finishes but the four road stages feature 13 categorised climbs with Saturday’s queen stage featuring four category-one climbs, including two ascents of the Col de la Croix.
Andrew Talansky and Rui Costa, second and third last year are present as well, while other established Grand Tour riders in the field include Alejandro Valverde, Ryder Hesjedal, Roman Kreuziger and Jurgen Van den Broeck.
Mark Cavendish will look for sprint victories but his chances will be limited by the parcours and Omega Pharma Quick Step also have world time trial champion Tony Martin in their line-up.
Sport Director Brian Holm said. "There is a prologue and a final TT for Tony Martin, and then some mixed stages for the other guys — for example, a stage hunter like Gianni Meersman. It's also a good preparation for the Giro d'Italia.
"If there is a sprint, we have Cavendish who is tuning up his condition for the Giro. We have a balanced team, so I think we can be a protagonist throughout the race. That is our objective, but we will see each day."
