Sky's double option with Wiggins and Uran at the Giro d'Italia

Bradley Wiggins may no longer be leading Sky through the mountains in the Giro d'Italia. After winning today's stage finish to Altopiano del Montasio, Colombian Rigoberto Urán could take on the captain role.

"It's not just about Brad," team principal, David Brailsford said.

He spoke with a small group of journalists including Cycling Weekly huddled around the team bus. The questions centred on how Wiggins faired - he lost 49 seconds today - and who is leading Sky for the next two weeks of the Giro d'Italia.

"It depends on what the team strategy is," added Sir Brailsford. "It's a team at the end of the day."

Team dynamics seem to be changing. Already on Sunday heading to Florence, Colombians Urán and Sergio Henao were given free rein while Wiggins drifted behind a group with his main rivals.

Henao lost ground today, but Urán broke free and moved to third overall. He sits 2-04 minutes behind leader Vincenzo Nibali (Astana); Wiggins is at 2-05.

"We still don't know, we have to wait," Urán said in the press conference when asked if he could ride for the overall win.

Asked if he would like Wiggins to work for him, he said, "For now, we need to wait. At this point, the team wants to race a little bit differently, and we want to continue like that."

Urán, silver medallist in the London Olympics road race, placed seventh and won the white jersey in the Giro d'Italia last year.

Nibali won the Vuelta a España and placed third behind Wiggins in the Tour de France last year. He is keeping an eye on his Colombian rival.

"Our team has a good advantage, but I'm going to keep an eye on both Wiggins and Urán," Nibali said in the press conference. "I don't know what they are going to do; it depends on Sky's management. We have to try to interpret their moves."
