The 2025 retail Ezone 100 lists a 24.5 / 26.5 / 23 mm beam profile. The weight and balance figures below are measured unstrung.
- Head size: 100 in²
- Unstrung weight: 300 g
- Unstrung balance: 320 mm
- String pattern: 16 × 19
Compare the Alternatives
Wilson Defyer 100 V1 shares the 100 in² head, 300 g unstrung weight and 16 × 19 pattern. Its 315 mm unstrung balance point is 5 mm closer to the handle end than the Ezone’s 320 mm. The balance point locates where the racket balances; it is a different measurement from swingweight.
