Hey, My front chain ring and my rear cog on my profile aren’t in line with each other making my chain not go on straight. Therefore making the chain creak when it goes round the chain is brand new and I am running gearing 18, 12. I was thinking can I swap the cog round so the teeth are on the outside and the smooth part is on the inside. Its hard to explain so I will draw a picture. So do you think i should try it and do u think it would work? Thanks, John
