Contador joins Armstrong in wind tunnel testing

Alberto Contador flew to the USA yesterday for aerodynamic wind tunnel testing in San Diego, California. The winner of this year's Giro d'Italia and Vuelta a España will accompany new teammate Lance Armstrong and Levi Leipheimer today at the San Diego Air and Space Technology Low Speed Wind Tunnel.

Contador will use the facilities to work on a new time trial helmet. "We will work with my sponsors, Trek and Giro, for the next season. I am going with a lot of motivation, because the races are won by very little time [difference] and with the time trial I still have a good margin for improvement," he said in a press statement.

It will be the first meeting between Armstrong and Contador since the former announced his comeback to the sport in September. The two will both race in Johan Bruyneel's Team Astana.

Contador is targeting the Tour de France to add to his 2007 victory. Armstrong, who will debut with the Tour Down Under, will race the Giro d'Italia for the first time in his career. He has not yet decided if he will return to race the Tour.

Armstrong won the Tour de France from 1999 to 2005, before retiring after his last win. He completed in his first time trial since retiring this weekend at the Tour de Gruene.
