I have a city bike with a 3 gear hub on the back.
From some time now, from time to time I hear (I think) the chain clicking/cracking (noise) specially when going up a ramp.
Initially I though it was just missing oil, but after greasing the chain it still does the same noise.
Any tips to solve that?
Extra info: When I hear the noise it seems like the chain jumps in the cog?!?! I am not sure though.
