Kelme rider Alejandro Valverde stole some of the limelight from the dominant ONCE team by winning the punishing 15th stage of the Tour of Spain.
Valverde outsprinted Colombia's Felix Cardenas and Spain's Roberto Heras at the mountaintop finish to the 172km stage at Sierra De La Pandera.
Isidro Nozal retained his lead despite suffering when third-placed Heras attacked with six kilometres remaining.
The day included what is considered to be the hardest climb of the race.
And ONCE rider Nozal lost more than a minute to the three stage leaders on
the steep slopes of La Pandera, where Valverde took his second stage win of La Vuelta.
Nozal still holds an advantage of three minutes and three seconds over second-placed Igor Gonzalez de Galdeano in the overall standings.
"I've come out of here very pleased because I only lost the time I expected to lose," said Nozal, who kept his
leader's jersey for an 11th day.
"It was logical that I should have problems here because I'm not a specialist climber.
"Now I think I should be able to hold on at Sierra Nevada on Tuesday, a climb which suits me much better because it is not so steep even if it is much longer."
Valverde's win moved him up to fifth in the overall standings.
"I was as surprised as anybody else to win today," said the 23-year-old. "What was most important was the work done by my team mate Oscar Sevilla.
"As I can't handle really steep climbs, his support helped to keep me in the picture. Then it was all up to me to win the sprint."
