Patrik Sinkewitz has provided the German cycling federation with information about "the art and manner that doctors and team doctors provided doping products," said Peter Barth, head of the federation's disciplinary committee, according to press agency dpa. "The Sinkewitz testimony concerned his time at Quick.Step-Innergetic from 2003 to 2005 as well as his time at T-Mobile in the year 2006."
Sinkewitz appeared before the panel this week because of a positive control for testosterone. He hopes to have his suspension reduced by cooperating and providing information.
T-Mobile spokesman Stefan Wagner told Cyclingnews, "I can't comment on this information because we don't know what he has said and what happened in the team in 2006. The new management took over the team on request of T-Mobile at the end of the 2006 season. Since then we have made significant changes which continue."
