Hello all! This isn't a very unique problem and would love just a quick response or some advice! I have been struggling with my rear sprocket to center it and mount it on the rear wheel. Its relatively easy to center before I start tightening it down, but as soon as I start... It does what it wants and runs away to one side! Long story short, I broke a chain because of wonky chain tension and I need to fix it. What are some good methods of keeping the sprocket centered even as you are tightening it into place? Is there possibly some way I can use a solid guide that will allow it to tighten into place?
