Pro Staff Tennis Racket – Technical Specifications
The Pro Staff racket is designed for players who require precise control over ball trajectory and consistent energy transfer. Its geometry is optimized to reduce torsional twist during off‑center impacts while maintaining a predictable swing feel. These characteristics help minimize unforced errors in high‑intensity match play.
Key Performance Parameters
Weight is measured at 310 g ± 5 g when strung with a standard 16 mm synthetic gut, providing a balance point of 315 mm from the butt cap. This distribution yields a swing weight of approximately 320 kg·cm², suited for players who generate moderate to high racquet head speed.
Frame stiffness, evaluated via RA (Rigidity Index) testing, falls within 68–72 RA, offering a blend of feedback and power. The head size is 95 in² with a string pattern of 16 × 19, which influences spin potential and sweet‑spot size. These values are typical for tournament‑level rackets and can be fine‑tuned through custom layup adjustments.
| Parameter | Typical Range | Unit | Notes |
|---|---|---|---|
| Weight (strung) | 305–315 | g | Measured with 16 mm synthetic gut |
| Balance Point | 310–320 | mm from butt cap | Affects maneuverability |
| Swing Weight | 315–325 | kg·cm² | Influences power generation |
| Stiffness (RA) | 68–72 | RA | Higher values = more power, less flex |
| Head Size | 95 | in² | Standard for control‑oriented frames |
| String Pattern | 16 × 19 | – | Promotes spin and durability |
Material Construction
The frame utilizes a high‑modulus graphite base woven with a unidirectional layup to achieve targeted stiffness along the longitudinal axis. This orientation minimizes energy loss during impact and improves feel stability.
Kevlar reinforcement strips are positioned at the 3 and 9 o’clock positions to increase hoop strength and reduce frame deformation under high string tension. The combination yields a dampened vibration profile while preserving responsiveness.
Applications in Professional Play
Players who favor a controlled, flat‑hit baseline game benefit from the racket’s low torsional flex, which translates to consistent shot depth. The moderate swing weight allows rapid preparation for aggressive returns without sacrificing stability on defensive blocks.
- Baseline power generation with minimal racquet twist
- Serve‑and‑volley transitions requiring quick maneuverability
- All‑court versatility where spin and control are balanced
Quality Control & Testing
Each racket undergoes weight verification using a calibrated scale with ±0.1 g tolerance before stringing. Balance is measured on a precision pivot system to ensure the mass distribution aligns with design specifications.
Stiffness is assessed via a three‑point bend test, and vibration damping is evaluated with a laser‑based modal analyzer. String bed uniformity is checked by measuring tension loss across the main and cross strings after a 24‑hour preconditioning period.
