The UST Mamiya Competition 65 Series Wood Shaft is a trusted, versatile graphite shaft engineered for club builders and golfers who demand fitting flexibility without compromise. Its lightweight combination R/S flex design covers a broad range of swing speeds, making it an ideal stock or upgrade shaft for drivers and fairway woods. With a mid-high launch profile and controlled torque, this shaft helps players unlock more distance and a consistently smooth feel through impact.
Rather than producing separate Regular and Stiff shafts, UST Mamiya engineered the Competition 65 with longer parallel tip and butt sections so a club builder can dial in the precise flex by following the trimming guide. One shaft SKU therefore fits a wide range of players, reducing inventory complexity for workshops and custom fitters alike.
The R/S version features a mid kick point that produces a mid-high launch angle — the sweet spot for most recreational and competitive amateur golfers seeking extra carry distance without ballooning trajectory. Combined with a 5.8° torque rating, the shaft delivers stable, consistent ball flight from tee to fairway.
At ~67 g the Competition 65 sits in the lightweight graphite category, helping golfers generate higher clubhead speeds for greater distance compared to heavier steel or mid-weight graphite alternatives. The durable graphite layup also dampens vibration for a smoother feel at impact.
The .335" tip diameter is the industry standard for drivers and fairway woods, ensuring the Competition 65 slips directly into the vast majority of modern hosel designs — from OEM stock builds to custom clubhead assemblies — without adapters or modifications.
