I have a kona humu humu nuku nuku apu a a, and i've regretably let it get in a bad state so i am going to sort it out by getting every thing apart from a frame. but what i need help with is that my kona has a 42 tooth cog on the front. I can only find a 40 tooth cog online. How much of a change will there be with two teeth difference.
