With a ten-second lead in the general classification, the Slovenian, 33, resisted several attempts by the Belgian during the six climbs of the Montjuich hill that punctuated the 7th stage (135 km) contested in the streets of the Catalan capital.
Both men finished detached and the leader of the Jumbo-Visma team left the stage victory to his rival Soudal-Quick Step without contesting the sprint.
"We expected his attacks. The seven days were difficult, but I had the legs. I am happy to add my name to the list of winners of this historic race," said the Slovenian, winner for the first time of the Volta, one of the oldest stage races (102nd edition).
In great form, Roglic, already winner the previous week of Tirreno-Adriatico in Italy, had taken the lead of the general classification of entry by winning the first stage.
The two cadors did not let go on the steep roads of the Catalan hinterland, the young Belgian of 23 years winning the third stage ahead of Roglic and the Slovenian the fourth, the most difficult, ahead of Evenepoel, still in a handkerchief.

"I knew it would be difficult but we had to try. It was a great battle. I'm very happy with my week," said the Flemish, who honoured his world champion jersey.
The winners of the last four Vueltas (Evenepoel in 2022 last, Roglic the previous three) will meet from 6 to 28 May on the roads of the Giro to try to add another grand tour to their palmares.
