Radioshack-Nissan-Trek have announced their Tour de France roster but the question remains as to who will lead the team in the race.

With Andy Schleck out having fractured his sacral at the Critérium du Dauphiné, Frank Schleck, Chris Horner, Andreas Kloden, Yaroslav Popovych, Jens Voigt, Maxime Monfort, Fabian Cancellara, Haimar Zubeldia and Tony Gallopin having been named in the nine-man line-up.

Frank Schleck is the form rider, having finished second at the Tour de Suisse, but the 32-year-old, who finished third in last year’s Tour de France behind Cadel Evans and brother Andy, told Belgian newspaper Het Nieuwsblad on Monday that he does not believe he can carry that momentum through the Tour.

“I don’t want to be captain. I can’t continue to perform at top level,” said Schleck.

Radioshack-Nissan-Trek’s general classification hopes could then rest with any one of Horner, Kloden, Popovych, Monfort and Gallopin. Horner, who was initially left of the team’s long list for the race, is one of two 40 year old’s in the squad, alongside Voigt.

With Radioshack’s general manager, Johan Bruyneel, under investigation by the United States Anti-Doping Agency, and the lack of a stand-out leader, the team’s Tour preparations have been far from perfect but their ambitions for the race will be unveiled at a press conference on Thursday.
