Peter Kennaugh, David Lopez and Ian Stannard were part of the line-up which helped Froome succeed Bradley Wiggins - who is heading into the final year of his contract with the team - as Britain's second winner of Le Tour.
Luke Rowe, Salvatore Puccio, Sergio Henao, Chris Sutton, Danny Pate and Xabier Zandio have also signed alongside Froome. Two of the 28-year-old's key support riders - Richie Porte and Geraint Thomas - had already extended their contracts mid-season.
"This has been an incredible year for me and I'm delighted to finish it off by signing a new contract with Team Sky," said Froome. "I've been with this team since the start and I know this is the right place for me to continue to grow as a rider. It's an honour to be a Team Sky rider and I hope to play a big part of its success for years to come."
That enthusiasm was also echoed by Rod Ellingworth, the team's performance manager. "We've consolidated what is an incredibly strong group of guys," he said.
