Curve left: click; curve right: click!

Now I drove 2800 kilometers to Holland, North Germany and back home, and the dear saaBeenchen starts to click. Especially with the steering. Listenable only in open mode, but extremely annoying. “Click” at every turn, even when parking, 20,000 KM and me creepy. Or drive in front and back.. “klinck”. Is it nice… but are these bike camps? Has anyone experienced such a phenomenon? Gruss vom Mütz
