London - Former Tour de France champions Chris Froome and Bradley Wiggins were named in the Great Britain team for the Road World Championships in Spain that was announced on Wednesday.
But while Froome, who recently came second in the Tour of Spain behind Alberto Contador, will spearhead a nine-man team in the men's road race, Wiggins will only feature in the time-trial.
Froome, the 2013 Tour de France winner, is joined in the road race squad by Geraint Thomas, Pete Kennaugh and David Millar, who is due to retire at the end of the season.
British Cycling technical director Shane Sutton said: "I'm pleased with the teams we've selected for the UCI Road World Championships. Across the board, we have some real podium contenders.
"For the men's road race, Chris proved he's in good shape by coming second at the Vuelta and I'm pleased David Millar will be leading the team in his last outing in Great Britain kit."
The line-up for the men's road race in Ponferrada on September 28, the final day of the competition, is completed by Steve Cummings, Luke Rowe, Yates twins Simon and Adam, and Ben Swift.
Wiggins, who won the Tour de France in 2012 before adding the time-trial gold medal at the London Olympics, will compete in the September 24 race-against-the-clock, alongside Alex Dowsett.
Lizzie Armitstead leads the six-strong women's squad, which also includes two-time junior world champion Lucy Garner but does not feature a competitor for the time-trial.
