ABOUT THE PRODUCT
Parallel Design. Built for Speed and Consistency.
The Speed GT 4.0 represents a modern approach to parallel shaft performance, combining advanced carbon construction with exceptional consistency, speed and shooting forgiveness.
Designed for recurve, barebow and compound archers who demand speed, consistency and dependable performance, the Speed GT excels across a wide range of outdoor target, field and 3D disciplines.
Built around a lightweight high-performance parallel shaft platform, the Speed GT utilizes higher modulus carbon materials to achieve a slimmer outside diameter than many conventional 4.0mm carbon shafts while maintaining excellent strength and durability. The reduced profile helps minimize wind drift, while the parallel design provides a forgiving tuning window and dependable setup characteristics across a wide range of bows and shooting styles.
