Hi all, I've just done a few hundred miles off road in the Alps, I started to notice a loud clicking when rolling the bike forwards or backwards. Assuming it was to do with chain tension, I slackened the chain right off and checked every link for tight spots, it seemed ok. Adjusted the chain to spec the clacking is still there. The bike has only done 6000 miles. I took the front sprocket cover off and I can make the gearbox sprocket click with my fingers, it is loose on the countershaft. The bolt is tight. Has anyone else experienced this, and is there a fix?
