The 30 year old will tackle the inaugural Colombia Oro y Paz stage race (commencing February 6) and is hoping to begin the next chapter of his career on the front foot.
After six successful years with the Movistar team, Castroviejo is relishing a new environment and has quickly settled into Team Sky life off the back of two training camps in Mallorca.
He explained: “I have watched Team Sky for a lot of years. They are an ambitious team and I also have these ambitions. After many years in one team you can become comfortable and for me, in a sport that carries a lot of sacrifice and training, I wanted something different and a new incentive. In the small time I have been with the team it is clear to see the quality of the team and I can see that I made the right decision.”
