Tom Dumoulin and Warren Barguil have signed three-year contract extensions with German team Giant-Alpecin.
The Netherlands' Dumoulin, 24, is one of the best time-triallists in the world and also established himself as a potential Grand Tour contender by finishing third at last month's Vuelta a Espana.
France's Barguil, 23, is a climber who won two stages of the 2013 Vuelta and finished 14th at this year's Tour de France.
Both will now stay with Giant-Alpecin until at least 2018.
Chief executive officer Iwan Spekenbrink said: "We are delighted to continue working with Tom and Warren to help them develop further as riders and achieve their maximum potential.
"This year we have seen Tom make a great step forward in his development both as a rider and as a person, which has led to some impressive results already.
"With Warren, we sent him to this year's Tour de France to learn and to discover his capabilities in a race like the Tour, which will be an important step in his development as a GC [general classification] rider."
