France's David Gaudu won Saturday's 11th stage of the Vuelta a Espana after the start was delayed following a protest led by Ineos Grenadiers.
It followed a decision by stewards on Friday that put Primoz Roglic back into the overall lead.
Groupama rider Gaudu pulled away from Spaniard Marc Soler of Movistar in the final metres of the 170km stage, which finished on the Alto de la Farrapona.
Roglic maintains his lead at the top of the standings.
The Jumbo-Visma rider is on the same time as Ineos' Richard Carapaz but has the red jersey on better stage placings so far.
Ireland's Dan Martin remains in third place, 25 seconds behind Roglic.
Sunday's 12th stage will finish at the top of the challenging Angliru - a 12.4km ascent at 9.9% with the last seven kilometres averaging a gradient of 13% and featuring a section above 20%.
Saturday's start from Villaviciosa was delayed following the protest.
After Slovenia's Roglic burst clear to win Friday's stage, stewards decided that the first eight finishers had created a large enough gap to split finishers on time.
It meant Carapaz lost the overall lead, but Ineos were angry as the rules were changed after the stage.
The rules state that on stages expected to finish in a bunch sprint, time gaps are counted if there is a gap of three seconds or more between groups.
