Play may be a good thing, but it came to the point where my chain will pop off at abrupt stops. Thanks for the good responses. Too be more specific, I have horizontal drop-outs, and when my hub is pulled all the way to the back my chain is still slightly loose. I took a link out, but then the hub wouldn't even make it into the drop outs at all. Maybe I should get a half-link? I will also get a lockring, and update with how it goes. Lastly, should I then worry about my bottom bracket at all. The threads are protruding on the non-chain side and there is nothing between the threads and the crank (Maybe I'm suppose to have something there). Anways, my bike is as much as a trajedy as my lack of knowledge. Thanks again for the advice.
