Ride Business, the Swiss trade publication for the bicycle business, reports that Athleticum, one of Switzerland’s leading retail chains, is losing two of its top managers: Stéphane Castrichella, the chain’s top buyer, has already left the company at his own request. André Afentoulidis, Athleticum’s managing director, will leave by the end of January. He will be replaced by Urban Neuhäusler, so far general merchandising manager for beauty/children/men/sports at Manor, the department store company, which belongs like Athleticum and Aigle to the Maus Frères group.
