South Africa’s Robbie Hunter and veteran Australian sprinter Robbie McEwen have signed to race for seven-time Tour de France winner Lance Armstrong’s RadioShack team in 2011, it was revealed on Thursday.

Both men were part of the Pegasus Sports project which failed to get a ProTour licence for the new season and they opted to change teams.

Lance Armstrong and RadioShack teammate Levi Leipheimer will race in the 2010 Leadville 100 mountain bike race next weekend.

Armstrong is the defending champion having won last years race in a record winning time of 6 hours, 28 minutes, 50 seconds.

A Chinese rider on Lance Armstrong’s Team RadioShack has been confirmed as testing positive for banned substances, an official newspaper reported on Sunday.

Li Fuyu’s B sample came back positive for Clenbuterol, an anabolic agent that can be used to reduce body fat, China Daily reported, citing Zhang Bin, secretary-general of the Chinese Cycling Association.

Two French riders in a day-long break, Bastille Day and the Tour de France… it would have been an irresistible mix, except that Sergio Paulinho hadn’t read the script. Team RadioShack’s Portuguese domestique salvaged something from this year’s Tour with victory in Gap this afternoon, dashing the dreams of the locals.

Johan Bruyneel said RadioShack will rally its forces around Levi Leipheimer after Lance Armstrong lost all hope of winning the 2010 Tour de France. Armstrong lost 11:45 after a crash at the base of the Col de la Ramaz knocked him out of contention, but Leipheimer kept RadioShack’s podium options alive after he finished safely with the elite group of 13.

Although this Tour de France will be his last, Lance Armstrong isn’t finished with elite-level racing just yet. The seven-time Tour champion is planning another comeback next year — in triathlon. The plan is to race triathlon under the RadioShack banner. Lance is also considering doing the Cape Epic next year.

RadioShack has not made it onto the list of 22 teams to been invited to ride the Vuelta a España, set to start Aug. 28 in Sevilla. Sixteen teams were already selected, but RadioShack was not among the final six wild-card selections revealed Monday.
