Edvald Boasson Hagen of Norway finished 10th on the last leg of the seven-day UCI World Tour race, as the South African team achieved a total of six top-10 stage finishes.
Cummings was eighth in the opening time trial, while American Tyler Farrar was fifth on stage two, and German rider Gerald Ciolek and Hagen ended second and sixth respectively on the penultimate stage.
Olympic time trial champion Fabian Cancellara (Trek Factory Racing) won a closely fought final leg, but Colombian Nairo Quintana (Movistar), who won last year’s Giro d’Italia, held on to secure the overall victory.
“I am super happy with the results over the complete week,” MTN-Qhubeka head of performance Jens Zemke said in a statement. “It was an enjoyable race for the team. They connected well, we did good leadouts and we have good results.”
