Betancur arrives at the Spanish team after a troubled tenure at French outfit AG2R, a move he hopes will recissicate his flagging career.
He started well at AG2R, landing podium results at Flèche Wallonne in 2013 and completing a strong Giro d'Italia later that year, finishing fifth overall claiming winning the best young rider classififcation.
The following year he won Tour du Haut Var and Paris-Nice and looked on his way to a glittering career, joining the rest of the Colombian climbing cohort in shaking up the sport.
But his relationship soured at AG2R and in 2015 he struggled for form and fitness, only showing glimpses of his talent. It remains to be seen if the discipline at Movistar will bring him back on track.
Moreno on the other hand is a consumate professional with 11 seasons and numerous victories under his belt, many during the past five years at Katusha.
He had previously spent two year's at Caisse d'Epargne (2008-09), the precursor to Movistar, so it's a bit of a coming home for the 34-year-old from Madrid.
A top-ten finisher and multiple stage winner at the Vuelta a Espana, Moreno is also useful in hard classics like the Flèche Wallonne, which he won in 2013. More recently he finished second at the Giro di Lombardia behind Vincenzo Nibali (Astana).
However, Moreno's real utility at Movistar will be as a super domestique for team leaders Nairo Quintana and Alejandro Valverde.
