NI SERIES
NI is a unique "50t" hybrid shaft made of carbon. Unlike the ICHI shaft, it is specifically designed to maximize head speed. Initially, TRPX believed that a 50t pitch-based carbon design would enhance shaft repulsion. However, due to the fragility of pitch-based 50t, a 40t pan-type is used for each layer of pitch, resulting in a significantly heavier shaft.
Therefore, TRPX developed Hybrid 50t, a revolutionary carbon material. Hybrid 50t is a sheet that combines the powerful rebound of 60t pitch carbon with the flexibility and durability of 40t pan carbon. This innovative material allows us to create a strong, lightweight shaft with just one layer, delivering optimal playability and swing speed.

What is HC-50T?
The hybrid 50t is a unique carbon sheet created by combining 60t pitch carbon and 40t pan carbon.
60t pitch carbon is made from coal tar and has a strong ability to return to its original shape, but is weak in strength and difficult to bend. However, these fibers are susceptible to breakage under high stress. 40t bread type is made of acrylic, which is the opposite of the 60t pitch type and is flexible and almost never breaks. However, it lacks the immediate recoil properties of pitch carbon. Hybrid 50t is a carbon sheet made by combining these materials.
