Tryangle TU-01 Dedicated Small Diameter Front Cover Assembly This is a set of three items: a small diameter front cover, a dedicated line snubber, and a dedicated rotor nut. The "small diameter" front cover was originally planned for the TU-01. While the current diameter was adopted to reduce winding resistance, the small diameter cover offers many advantages in environments where repeated short-distance casting is required, such as "control of line release amount," "improved casting accuracy," and "ease of line feeding." There is also the disadvantage of increased winding weight, but please use it as another option to bring out the potential of the TU-01. Thank you for viewing.
