Re: how to mount back sprocket on a stingray??
Since you mentioned disc hub....one of our sprockets would be a direct bolt on at that point....If you wanted to try working a disc brake too, the Top Hat Sprocket Adapter may make that happen (to be honest I have never tried to get it all to work on a very wide rear tire....I am assuming the tire is wider than a mountain bike tire?).
Hope this helps you.
