Overview

Volkl V-Square holds the top score for bite (string-on-ball friction) in the Tennis Warehouse University String Lab. The 4-sided square profile with razor-sharp edges creates vicious snapback and maximum spin potential. Made with an exclusive material for improved comfort with minimal tension loss, V-Square sits between Cyclone and Cyclone Tour in terms of overall feel while offering perhaps the best spin potential in the Volkl lineup.

Best for

  • Maximum spin seekers
  • Heavy topspin baseliners
  • Players with western/semi-western grips
  • Those who prioritize spin over everything else

Not ideal for

  • Players with arm sensitivity
  • Flat hitters
  • Those seeking soft, muted feel
  • Players needing maximum durability (thin gauges)

Pros

  • #1 bite score in TW String Lab
  • Maximum spin potential with square profile
  • Good pocketing despite firm feel
  • Predictable response on full swings
  • Wide gauge selection for spin customization

Cons

  • Thin gauges break quickly
  • Not for arm-sensitive players
  • Limited to one color (Lava)
  • Premium priced vs regular Cyclone

Stringer notes

Sharp edges require careful handling. 19 gauge is a "spin monster" but may only last a few sessions. Static stiffness: 0.65 kg/mm.

Break-in period

Minimal. Plays well from first hit.

When to replace

Every 10-15 hours for thin gauges, 15-20 hours for thicker. Replace when edges feel worn.

Hybrid setup ideas

  • Natural gut mains with V-Square crosses for Federer-style setup
  • Wilson NXT crosses for comfort
  • Tecnifibre X-One Biphase crosses

Used by

Various club and collegiate players
