Sorry It's me again Last night I cleaned my bike, sprayed her with GT85 and took her for a wee spin. Now today coming home from work I could hear a noise, down at the gears. (i'm sorry if I not making sense). So I turned her up side down and turned the pedal, sure enough there was the noise. It's coming from the mec ???it's moving??? and the noise sounds like they are crunching/tapping (cant see them crunching together just a noise), now I have in the past buggered about with the screws and got a right telling off from the guy that sorts my bike. Should I try turning the screws and sort it or leave it alone? Do I make sense? cos I dont know the technical terms for the parts of my bike.
