ROSEVILLE, California— Hireko Golf is excited to announce the expansion of the SK Fiber Supernova shaft series with three new flex options: 40S, 40X, and 50X. The S (stiff) flex and X (Extra Stiff) flexes are for golfers with faster swing speeds, yet a smoother tempo who are seeking a lightweight driver or fairway shaft option.
These new flex options make it easier for golfers and clubmakers to adjust weight and feel to better match different swing styles while still maintaining the trusted Supernova performance.
The Supernova family includes three weight classes designed to fit a wide range of swing types:
- Supernova 40 – An ultra‑lightweight option ideal for smoother tempos or moderate swing speeds, helping generate faster clubhead speed and added distance.
- Supernova 50 – Offers a balanced blend of speed and stability, making it a versatile fit for a broad range of players.
- Supernova 60 – Built for maximum control, providing additional weight and precision for aggressive tempos and higher swing speeds.
Each shaft is constructed from 40‑ton high‑modulus aerospace‑grade carbon fiber, delivering exceptional strength, faster recovery, and tighter dispersion. With a mid‑launch, mid‑spin profile, the Supernova series fits golfers with swing speeds ranging from 60 to 120 mph, making it a versatile option for a wide variety of players.
The expanded SK Fiber Supernova shaft lineup is available now, starting at $69.99. Purchase at www.hirekogolf.com or through authorized Hireko distributors.
