Overnight leader Wilco Kelderman (LottoNL-Jumbo) lost the yellow jersey to Henao, with visible rips in his clothing suggesting he had crashed during the stage. Contador sits in second at six seconds, with Thibaut Pinot (FDJ) in third at 10 seconds.
Rosa had been part of a large, 24-rider escape group but had gone solo after around 50km of the 159km stage. He quickly opened up a significant time gap as the escape group behind him splintered over the day’s eight categorised climbs.
The peloton containing the general classification favourites also fractured in the final 12km, with stage winner Mikel Landa (Sky) linking up with team-mate David Lopez from the earlier break, along with Simon Clarke (Orica-GreenEdge), Serge Pauwels (Dimension Data) and Carlos Verona (Etixx-QuickStep).
Contador attacked from the bunch with 5km to go, with Henao on his wheel. They quickly caught and passed Landa, and worked together up the final climb to distance their rivals.
Rosa’s time advantage was such that he had time to stop before the finish, dismount and walk across the line holding his bike aloft in celebration. Henao and Contador crossed the line together over three minutes behind Rosa.
There were several high-profile abandons during the stage, namely as a result of crashes on wet descents. British rider Simon Yates (Orica-GreenEdge), Fabio Aru (Astana), Daniel Martin (Etixx-QuickStep), Simon Gerrans (Orica-GreenEdge) and Ryder Hesjedal (Trek-Segafredo) were among those withdrawing during the day.
The 2016 Tour of the Basque Country (Vuelta al Pais Vasco) concludes on Saturday with a decisive, hilly 16.5km individual time trial.
