Evolution of strength.

Lightness of plastic, high rigidity of metal

The ideal shaft was born with the performance of these two.
The most unbreakable lightweight shaft in the world

The FitShaftCarbon is the world's most unbreakable lightweight shaft.

Light weight and extraordinary strength
By using reinforced plastic
By using reinforced plastic, we have achieved light weight and high durability.

By coating the densely intertwined carbon fiber with resin, the rigidity is equivalent to that of duralumin, a lightweight metal.

Adds the performance of Fit Shaft GEAR
By adopting the "Tough Top" and "Fit Joint" technologies cultivated through the development of the latest Fit Shaft GEAR, we have maximized the quality of the materials and achieved superior durability. It also inherits the easy identification of lock and spin and eight different full-length patterns.

Unparalleled development team
We have assembled an unprecedentedly strong development team consisting of leading experts from the Cosmo Product Development Department, material manufacturers, universities, and government agencies. The product was completed after many rounds of prototype testing.

Cost reduction
In order to increase the strength of the plastic shaft, a lightweight metal was used, but this increased the weight and cost. By using the latest carbon-fiber-reinforced plastic material, we were able to ensure mass-producibility and eliminate the high cost.
