A strong 7
You know what to do...
You running that w/o a singulator?
No. They are vertical dropouts but the gearing and chain tension is perfect with the teeth on the chain ring and cog right now. It works perfect. The vertical drops have a little play to them to tension the chain, if done correctly. If I wanted to change gearing I would have to add/remove links and see if it works.
Did you figure out what is up with the fix gear side?
