Peter Kennaugh, David López, Ian Stannard, Luke Rowe, Salvatore Puccio, Sergio Henao, Chris Sutton, Danny Pate, and Xabier Zandio have also signed contract renewals.
Sergio Henao will be joined by his younger cousin, Sebastian, on the team in 2014. The team has also signed Nathan Earle, Mikel Nieve and Philip Deignan.
Bradley Wiggins has one year left of his contract, but it is still not known if he will remain with the team beyond 2014.
"Everyone is excited to kick things off again in 2014 and we do so with what we believe is the most talented team in the world," said the team's performance manager, Rod Ellingworth.
"We've consolidated what is an incredibly strong group of guys over the winter. The team's core remains intact and that’s important going forward.
"Everyone is committed to keep improving and we always look to provide the best environment for riders to do that."
Chris Froome says that it has been an incredible year and that he is "delighted to finish it off by signing a new contract with Team Sky."
"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 impossible to win races without the right team beside you so I'd like to thank everyone at the team for their continued support. 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."
