Olympic champion Tyler Hamilton won the eighth stage of the Tour of Spain on Saturday, a 40km individual time trial.
Fellow American Floyd Landis regained the overall lead.
Phonak rider Hamilton shrugged off an injured wrist and covered the course in 47 minutes 16 seconds, 15 seconds faster than Colombian Victor Hugo Pena of US Postal.
Landis finished third, but regained the overall lead to stand 10 seconds clear of another US Postal rider, Spain's Manuel Beltran.
Hamilton dedicated his victory to "everyone affected by the attacks of the 11th September 2001 which have changed the world."
The American, who lies third overall, 22 seconds down on Beltran, said: "As Olympic champion, anything less than victory would have been a disappointment."
Nursing his injured right wrist from a crash on stage four, Hamilton, fourth overall in the 2003 Tour de France despite a broken collarbone, said: "I'm used to riding with pain."
