Line Roller Impact For Shimano

IOS Factory Line Roller Impact

For shimano 1k - C5k

By improving the rotation of the line roller, retrieve sensitivity is improved, line trouble is reduced, and line is wound in alignment on the spool no matter what the line tension is, resulting in excellent stable release when casting and improved distance with good guide nuke. 

The rotation can be confirmed by the movement of the well-designed dot holes, which rotate even with the weight of the line when the lure is not attached.

In reality, the line roller does not turn only when a fish hits, but it must always turn, even when dealing with line slack or when retrieving a lure with very little resistance, or it will wind twisted line onto the spool.

When casting, those lines can be released all at once, which can lead to backlash and other problems as well as reduced casting distance.
