Lance Armstrong will ride in support of Astana teammate Levi Leipheimer in the Giro d'Italia, saying he is not ready to contend for the title.
The seven-time Tour de France winner broke his collarbone in a crash in March and hopes to win at least one stage of the Giro, which begins Saturday in Venice, Italy.
"While at the beginning of the year my objective was to contend, with the crash I'm not sure I still can," Armstrong said Tuesday at a meeting with Italy's foreign minister, Franco Frattini, to back his campaign against cancer.
"Before that I was ahead of schedule. Now we're behind schedule. I have to go into the Giro knowing I'm not a contender for the overall. But we have a rider who is going for the overall, and I'll ride for him."
Armstrong helped Leipheimer win the Tour of the Gila in New Mexico last week.
Auctioning his bike: Armstrong plans to auction off his Giro d'Italia and Tour de France bikes, which will feature designs from artists including Shepard Fairey and Damien Hurst.
Armstrong has posted photos on his Twitter account of his bikes for the Giro. They feature an intricate yellow-and-black design by Fairey, who made the iconic Barack Obama poster.
"I collect his artwork," Armstrong said. "The bike that he did for this race I think is pretty stunning."
