After the Tour de France, the team completely changed; Team manager Olaf Ludwig left the team and was replaced by Bob Stapleton. Rolf Aldag, Allan Peiper and Tristan Hoffman became directeur sportifs. As already discussed Ullrich, Sevilla and Pevenage were dismissed from the team. Several riders who had been with the team for a long time such as Steffen Wesemann, Andreas Klöden and Matthias Kessler left or their contracts were not extended. Jörg Ludewig was put on suspension and his contract was not increased in connection with intention to dope previously in his career and before he joined T-Mobile. Eddy Mazzoleni who was in his first year for the team would also leave. The contracts of Bram Schmitz and Bas Gilling were not renewed. Dr. Lothar Heinrich, the team doctor since 1995, and Dr. Andreas Schmid set up a new comprehensive testing system. Following the revelations that came out of the Operación Puerto investigation, Heinrich allegedly nearly quit the sport but instead he joined with Stapleton and other team staff to create a new system of internal controls and health checks that he insisted would demonstrate that T-Mobile riders were clean and to restore credibility to the sport.
