2005 Tour best: n/a
Although not among the top-ranked teams, the French outfit have won a wildcard to appear at the Tour.
The team were left with no option but to withdraw from this year's race when five of its riders were forced to quit after being implicated in the doping investigation currently sweeping the sport. Rules state that a team, normally nine riders, must field at least six to start one of the major Tours. The decision means that team leader Alexandre Vinokourov, who was not one of the five riders named, would not be able to compete. The Kazakh star had high hopes of winning this year's race after finishing fifth in 2005. The team had already had a troubled build-up to the race. Team boss Manolo Saiz resigned after being named in the doping probe while Liberty Seguros withdrew its sponsorship.

Team leader: Alejandro Valverde
2005 Tour best: Francisco Mancebo, 5th
The team's name has changed a tad from last year, as has their line-up - with the highly rated Francisco Mancebo now heading up AG2R's efforts. Alejandro Valverde is a classy replacement as team leader.

Team boss: Eric Boyer
Team leaders: Sylvain Chavanel/David Moncoutie
2005 Tour best: Cedric Vasseur, 44th
Their riders were there or thereabouts for a host of stages without really delivering. That said, David Moncoutie made amends with victory on Bastille Day to give them something to cheer about. Watch out this time for Brit Bradley Wiggins.
Team boss: Roger Legeay
Team leader: Pietro Caucchioli/Thor Hushovd
2005 Tour best: Christophe Moreau, 10th

Team boss: Bjarne Riis
Team leader: Carlos Sastre
2005 Tour best: Ivan Basso, 2nd

Team boss: Marc Sergeant
Team leaders: Cadel Evans/Robbie McEwen
2005 Tour best: Evans 8th
Cadel Evans was the surprise package in the Tour's top 10 last season and, according to his team, has progressed as a rider a year on. If that wasn't enough, his outspoken countryman Robbie McEwen will be going for it in the sprints.
Team boss: Johan Bruyneel
Team leaders: Paolo Salvodelli/Yaroslav Popovych

Team leader: Iban Mayo
2005 Tour best: Haimar Zubeldia, 15th
On their day, the Basque climbers are simply unmatchable. Sadly for them, team leader Iban Mayo has steadily failed to deliver of late. Should he get it right in 2006, he and his team will be a force.
Team boss: Marc Madiot
Team leaders: Brad McGee/Sandy Casar
2005 Tour best: Casar, 29th
Brad McGee has promised so much since an impressive eighth place at the 2004 Giro without really delivering. Sandy Casar, a surprise fifth on the Giro this year, looks the likely contender to push in the general classification.
Team boss: Hans Michael Holczer
Team leader: Levi Leipheimer
2005 Tour best: Leipheimer, 7th
Levi Leipheimer will be eyeing a place in the top five and, despite his team talking up his chances, victory looks unrealistic. He should again have capable back-up in Georg Totsching, himself a top-10 candidate.
Team boss: Giuseppe Saronni
Team leader: Damiano Cunego
2005 Tour best: Eddy Mazzoleni, 13th
Prior to last year's start, all the talk was about the now departed Gilberto Simoni and current team leader Damiano Cunego, only for Eddy Mazzoleni to upstage them both. Cunego's fourth place in the Giro has once again seen people talk up his Tour chances.

Team leader: Stefano Garzelli/Danilo di Luca
2005 Tour best: Garzelli, 32nd

Team leader: Erik Zabel
2005 Tour best: n/a

Team leader: Floyd Landis
2005 Tour best: Landis, 9th

2005 Tour best: Michael Rogers, 41st
Juan Miguel Garate rode an impressive Giro d'Italia for the team - he finished seventh - but it remains to be seen if he has the legs for another big tour. Failing that, Tom Boonen and Paolo Bettini will be vying for stage wins.

Team leaders: Michael Boogerd/Michael Rasmussen
