PARIS — Cycling's world governing body banned German rider Stefan Schumacher for two years on Friday after he tested positive for a banned drug at the 2008 Tour de France.

The International Cycling Union's decision bans Schumacher from competition until Jan. 21, 2011.

The 27-year-old German already received a two-year ban from French races by the French anti-doping authority last month.

Schumacher said on his Web site Friday that he would appeal to the Court of Arbitration for Sport.

"One thing is clear: I have not doped and I have nothing to hide," he said.

French officials say they found traces of blood-booster CERA in Schumacher's blood in samples taken before and during last year's Tour. He won two time trial stages but could be stripped of the victories.

Schumacher was suspended by Team Gerolsteiner after the result became known in September. His new team, Quick Step, then dropped him.

UCI said it notified the German federation of the global ban.

Schumacher said the UCI had informed him in a fax that the world body would adopt the French agency ban. He complained that it did so "without examining the documents, without clearing up the inconsistencies and without a real hearing."

Also Friday, the UCI warned five teams that they could not start the Paris-Nice race this weekend because they haven't paid into a fund for a new anti-doping system.

UCI president Pat McQuaid said the five teams — Cofidis, Bouygues Telecom, Caisse d'Epargne, QuickStep and Silence-Lotto — haven't paid dues for the new "biological passport" system.

McQuaid said the five teams won't be able to start the first race in the UCI's European calendar unless they pay at least a portion of the $152,000 before "the close of business" on Friday.

The UCI said in a statement after McQuaid's news conference that Cofidis and QuickStep had come through with the required sum.

Francis Lafargue, spokesman for Caisse d'Epargne, said his team had anticipated paying in four quarterly installments "like last year. So there is a misunderstanding... It'll be worked out quickly. We can't accept threats from Pat McQuaid."

Cycling has been looking to turn the page on a string of doping scandals that have rocked the sport. This year, seven-time Tour de France champion Lance Armstrong is back on the circuit for some major races, including the Tour.

Asked about the prospects of a clean Tour this year, McQuaid said: "I think it will be a good Tour, it will be a good year for cycling overall.

"I don't foresee the scandals on the Tour like last year. That's not to say that there might not be one or two positives on the Tour."

The Paris-Nice runs from Sunday to March 15.
