Seriously confused and need somebody to redpill me on single speed freewheels & sprockets.
I have a flipflop hub, the single speed part that I use has 18 teeth, I'd like to switch to 16 teeth. Now I thought all I had to do was remove the sprocket from the freewheel, and put a compatible 16T on. But then I'm also looking at freewheels, and they all have a sprocket built onto it/come with one. Am I supposed to buy both at once?
This is the crappy Chinese one I currently have on
