Oliver’s SQ.X9 1.25 Black is a co-polyester squash string engineered for players who prioritise control and consistency over raw power. The monofilament construction produces the firm, direct response characteristic of polyester strings energy transfers cleanly at contact, the string maintains its shape under load, and shot placement reflects the player’s intent with minimal interference from string movement.
At 1.25mm, the SQ.X9 hits the standard gauge range for performance squash strings, providing solid durability for regular training and competitive play. Co-polyester strings hold their tension better than multifilaments, maintaining a consistent response over a longer playing period before the string bed needs replacing a practical advantage for players who train frequently.
Oliver’s string construction quality is consistent with the brand’s wider reputation for honest, well-made squash equipment. The SQ.X9 doesn’t overpromise extraordinary performance characteristics; instead it delivers reliable, accurate-feeling squash performance that advanced club players and competitive players can trust session after session.
Suited to technical players with developed swing mechanics particularly those who play a controlled, cross-court and length-focused game where accurate placement is the primary strategic tool. Sold as a single strung set.
