Teams sack riders as a matter of course, but rarely do team sponsors sack each other. Quick Step, thPICTURE BY TIM DE WAELE Quick Step owners Unilin Flooring announced in a statement on Tuesday that they are splitting with current co-sponsors Davitamon next season in order to avoid a conflict of interest within the Pro Tour. Supplements and vitamins manufacturer Davitamon are part of the Omega Pharma group that recently announced it is teaming up with Lotto to form the second of Belgium's two Pro Tour teams next season. The statement did not make clear whether Quick Step would remain as the team's sole sponsor or look for another backer to replace Davitamon. There was consternation over at Davitamon, however, with company CEO Marc Coucke apparently unaware of what was going on until he was contacted for a comment by Belgian press agency Belga. "We had got on very well with the people at Quick Step, and now they are showing us the door," he said. "We have never interfered in the conduct of the team, that's the domain of [team manager] Patrick Lefvre. "Where is the problem? Quick Step-Davitamon and Omega Pharma-Lotto ought to be able to be completely independent of each other. Quick Step has acted improperly towards us."
