so i think what i need to convert freewheel type wheel to singlespeed is to just remove my 7sp cluster, install a 1sp freewheel, put on a left threaded bb lockring, then try and get a good straight chainline.

if this sounds incorrect let me know. also anyone have a pic of a bb lockring i dont know what it looks like. i've installed bb's before but don't recognize which is lockring. thanks
