I'm still trying to sort the chainline and the chainlength but I'm very close to giving up because....
What is wrong with it?
If when you're at the back wheel of the bike looking down towards the cranks, and the chain is drifting outwards away from the rear cog, then try putting the front chainring on the inside, rather than the outside of the crank spider like you have now.
If it's drifting inwards then you can put spacers inbewteen the chain ring bolts to effectively shift the chainring further out.
