I currently have 33-20 gear ratio on a 29er, and am interested in trying out some different ratios on my bike. I am pretty new to riding single speed, and my question is what exactly will be involved in changing the ratio.
I ordered a set of various cog sizes to try. I'm thinking of going from 20 to 18 at first and seeing how that feels. Would I need to shorten the chain for this small of a change? I've never broken down a chain before.
