The Irishman was a consistent presence and his domestique work was instrumental to a number of big victories, including Paris-Nice, the Tour of the Alps, Clasica San Sebastian and the Vuelta a Burgos.
Set to enter his fifth year with the team in 2018, Deignan is happy to remain a Team Sky rider in surroundings that have seen him thrive.
On signing a new deal he told TeamSky.com: “It was a very easy decision. I’ve been part of the team now for four years, I’ve settled in nicely and I’ve made so many good friends on the team. I feel almost part of the family now, so it was an easy decision to stay.
“I like the way the team works with everything being quite scheduled out and planned. I find I work better in that environment and the team provides all of that for me with such a professional set up and coaching. We’re so well looked after on this team and I can’t take it for granted just how well we’re all looked after. It’s been a great experience for me so I’m looking forward to it continuing.”
