The last race the duo rode together was the World Championships in Firenze last September while the last race they rode together for Sky was the 2013 Tour of Oman.
Having secured overall victory at the Tour of California, Wiggins' next race will be the Tour de Suisse where he will be joined by the majority of riders who helped to success in America. Also on the start line for Sky are three riders who have just completed the Giro d'Italia — Dario Cataldo, Philip Deignan and Ben Swift — and Pete Kennaugh, who were part of last year's Tour-winning team.
"Both the Criterium du Dauphiné and Tour de Suisse are WorldTour events and we are looking to perform in both races," team manager Dave Brailsford said.
"Bradley heads to Switzerland with a strong team after a great win in California and we've got the right group for the Dauphiné, especially considering the nature of the course."
While Sky enter the two races looking for victories, they will also determine the final nine-man Tour de France team that will line up in Yorkshire for the Grand Depart on July 5.

"Both of these races will form part of our selection for the Tour" Brailsford said. "We have to name 13 riders in a long list during June and we'll do that from across the squad, including riders at the Route du Sud, not only those in the Dauphiné and Tour de Suisse groups."
Critérium du Dauphiné: Chris Froome, Vasil Kiryienka, David Lopez, Mikel Nieve, Danny Pate, Richie Porte, Geraint Thomas and Xabier Zandio. Tour de Suisse: Dario Cataldo, Philip Deignan, Joe Dombrowski, Peter Kennaugh, Christian Knees, Luke Rowe, Ben Swift and Bradley Wiggins.
