Grinding/vibration normal on lowest gear? (Smallest cog)
My folder come with 1x8 speed and I've done all the necessary adjustment. H limit screws, L limit, B screw, indexing and all that. On stationary test everything is fine, no chain rubbing but when I took it on a ride I feel some grinding/vibration on the lowest gear. Kinda like "grrg, grrg, grrg" and I can feel it on my pedal. Is this something to worry about? Should I make further adjustment?
