Going to buy new chain - called rocky mountain & they said I need a 112 link rk x ring. After a search, I thought I needed a 108.? Also want to buy a 12 tooth sprocket and a 48 back. Any advice here? Like to ride the woods - mud/hills/trails, and unfortunately like to go fast out in the open when I'm reved up.
13/49 13/50 12/48 12/49???
