"I'm very proud to be joining this team. I really like the international look and feel of it and it will be good to race with so many people from different nationalities," Kiserlovski said.
"This is a good opportunity for me, really the next step in my career."
General manager Johan Bruyneel added: "Robert is a rider with an attacking mind. We've been following him for some time now.
“He rode a nice Ardennes week, even though he was a novice in that kind of work. He was also very strong in the Tour, until he unfortunately crashed out of the race with a broken collarbone."
Kiserlovski, born and raised in Rijeka, is a massive fan of the Ardennes Classics but his true passion is the Giro d'Italia.
He explained: "I hope I will be able to race the Giro. Most riders prefer the Tour, but the Giro is my dream race."
In 2012 the 26-year-old finished fifth in the Flèche Wallonne. He had top-ten placings overall in Paris-Nice and the Volta Ciclista a Catalunya and he finished 13th in the Tour of the Basque Country.
"Robert is a strong addition to our roster and he will have a free role in certain races,” Bruyneel said.
“He's a rider that is capable of a lot on a good day, even though he didn't get full recognition of that yet. His results and development are promising and he has the right attitude.
“I'm confident that he will be able to improve even more in our outfit. He has the quality needed, we'll work on consistency now.”
