For some, these are the golden years, the era from 1988 to 1998, when Grundig sponsored the Mountain Bike World Cup. From September 22 to 24, 2023, an event will be held in Klosters to celebrate these early days of mountain biking. Among other things, there will be a race on the original route of the 1993 European Championships, the Swiss Bike Masters will be held as a revival and a festival site in Klosters will provide the perfect setting for vintage fans.
