Team Sky have announced the signing of Polish all-rounder Michal Golas from Etixx – Quick-Step.
The 31-year-old will join the British squad on January 1.
Golas has spent most of his career working as a domestique and is likely to fulfil the same role for Team Sky.
Golas told teamsky.com: "I'm very proud to be joining Team Sky and extremely motivated for next year. I have always admired the team's philosophy and the success they have achieved over the years.
"I can't wait to start learning from, and supporting, some of the greatest riders in the sport."
Team Sky principal Sir Dave Brailsford said: "He is a strong, solid all-rounder who will really fit into the engine room of the team and offer a robustness that we really need in that area. We are really excited to have him coming on board."
Golas rode this summer's Tour de France and then won the Kampioenschap van Vlaanderen last week.
Team Sky have not revealed the length of contract he has signed.
Golas becomes Team Sky's third new signing for the 2016 season and second of the day, after the acquisition of Italian Gianni Moscon was announced earlier on Thursday.
