Users will make lots of noise about the impact of gear ratio on speed. While gear ratio contributes to the overall retrieve speed, it is also influenced by the size of the spool. A small spool will retrieve less line as compared to a reel with a larger spool running at the same pace.  The retrieve rate is directly proportional to the amount of line a spool would pick up upon retrieval. The more line it takes, the faster will be the speed. Simply put, three key factors impact the retrieve speed i.e., gear ratio, the diameter of the spool, and your winding speed.
