Sprocket Changing Instructions
Replace the chain
The chain did not want to go back on easily for my Speedmaster, I went from a 16 to an 18, and it was as loose as it would get and I didn't want to pry anything. So, I just got the chain on the top part of the sprocket and turned the rear wheel until it fell into place. Just like on a bicycle, just a bit harder to turn.
On to the next step.
