German A is one of the best kept secrets in the bike industry - a highly technical German company that specializes in suspension and has developed some of the best-known suspension designs in the bike industry. We worked with German A to develop the GA Force for Dahon bikes. The result is hands down the best functioning 20” suspension fork on the market. No other fork even comes close. The German A air shock can be tuned to your weight and riding style through adjustments to stiffness and rebound damping. Only 1.3 kg.
