FRANKFURT, Germany (AFP) - Patrik Sinkewitz spent five hours giving evidence to the German Cycling Federation's (BDR) disciplinary committee including details about the doping methods at his old team T-Mobile, it was revealed on Thursday.

The 27-year-old, sacked during this year's Tour de France after his routine drugs test was found to have abnormal levels of testosterone, gave evidence in a marathon session to the committee in Frankfurt on Wednesday.

He has been co-operating with the BDR in an effort to get the normal two-year ban for his offence reduced.

"His statements were not expected to be revealing to this scale," the committee's chairman, Frankfurt lawyer Peter Barth, told German agency SID.

"He has disclosed his time at T-Mobile in 2006 and produced a very extensive picture about doping methods by doctors and team doctors."

A judgment is to be expected within the next two weeks and the committee must decide if further investigation is necessary.

T-Mobile will be bracing themselves for what Sinkewitz has revealed after they parted ways with doctors Lothar Heinrich and Andreas Schmid in May over allegations they supplied cyclists - including the winner Bjarne Riis - with banned drug erythropoietin (EPO) during the 1996 Tour de France.

That case is still being investigated.
