UST Mamiya

What UST Mamiya does

UST Mamiya is a Fort Worth, Texas-based designer and manufacturer of high-performance graphite golf shafts, founded in 1991 and operating as a subsidiary of Taiwanese conglomerate YFY Inc. The company sells through three primary revenue streams: OEM shaft supply to nine major golf equipment manufacturers (Callaway, Taylormade, Cleveland, Cobra, Mizuno, Ping, Titleist, Wilson, PXG); aftermarket sales through a global authorized dealer network spanning 30+ countries; and premium tier TSPX-certified shafts distributed exclusively through a TSPX Certified Dealer Network. Its product portfolio is organized into multiple sub-brands targeting distinct performance profiles, including LIN-Q PowerCore (flagship featuring Q-Ply material and proprietary nano-resin system launched January 2026), Recoil (#1 graphite iron shaft for 6+ consecutive years, 67% more efficient than steel), Proforce, ATTAS, Helium, and DART V. The company also operates two adjacent subsidiaries — UST Composites (arrows, archery, curling, industrial rollers) and UST ESSX (vaulting poles used by Olympic athletes) — leveraging its core carbon fiber engineering capabilities into non-golf verticals.

The company's go-to-market combines OEM-embedded distribution with a product-led consumer channel anchored by the SwingFit interactive shaft selection system, professional tour endorsements (Rickie Fowler, Ben Griffin, multiple Korn Ferry Tour winners), and dealer locator tools. Manufacturing relies on proprietary technologies including Q-Ply fiber architecture, nano-resin chemistry, discrete profile mandrel/layup designs per flex and launch option, and PowerCore multi-axis stability technology, with engineering operations supported by parent company YFY Inc.'s corporate infrastructure. Pricing is not publicly disclosed and is determined through the authorized dealer network and quote-based OEM contracts, with TSPX-certified premium products reserved for the certified dealer tier.
