"Bass One" has been loved for generations as Shimano's bass fishing rod. Casting, which is the basis of bass fishing, adopts a supple blank that suppresses blurring so that the angler can do more at will. In addition, in order to make it easier to catch changes in terrain and bites, the CI4+ reel seat achieves high sensitivity from hand. This time, new exclusive specs of "bait finesse system", "swim & big bait" and "solid tip" have been added, and it has been updated to a model that you can use for a long time with attachment to your hand as you use it.
