The T-Mobile cycling team are to part company with manager Olaf Ludwig in the wake of this year's Tour de France.

In three months' time, Ludwig's Olaf Ludwig Cycling (OLC) company will end its partnership with T-Mobile, and American Bob Stapleton will be installed as team manager with former T-Mobile rider Rolf Aldag as sporting director.

'Following a series of intensive discussions before and after the Tour de France, we will end our cooperation with OLC GmbH on October 31, 2006,' said director of sports communication Christian Frommert in a team statement.

T-Mobile claim the determining factor was a lack of confidence in the team management, as well as many radically differing ideas on the future strategy and direction of the team and the handling of the current doping problem.

The team dismissed racers Jan Ullrich and Oscar Sevilla as well as director Rudy Pevenage due to links with the 'Operacion Puerto' investigation into a Madrid-based doping ring, while the sport's credibility was further harmed when Tour winner Floyd Landis tested positive for testosterone.

The company is determined to help cycling clean up its act, and chief executive Rene Obermann admitted: 'After 15 years of involvement in cycling, we have a high level of responsibility towards the sport.'

Obermann also welcomed the new manager to the team, saying: 'We are delighted that in Bob Stapleton, we have gained a figure with 22 years of corporate management experience and the skills to direct the team.'
