Shimano Thunnus CI4


Lightweight and the power to stop big fish. Not a sentence you are used to hearing! Seemingly against the laws of nature. Thunnus takes a page from our Bicycle division using Carbon materials in high impact situations. Thunnus CI4 is a response to all the anglers out there in love with the ease of use and functionality that wanted the reel to shed some weight.
