Squash string aimed at delivering explosive power and exceptional comfort for competitive players. Confidence through aggressive shots and a forgiving feel during long sessions is the main promise. Is Tecnifibre X-One Biphase Squash String the right choice for players who want power alongside improved tension life?
⚡ At a Glance
- • Playing Feel: High elasticity with a softer response, designed for powerful, comfortable hits
- • Best for: Competitive and club players who prioritise power and comfort
- • Not ideal for: Players who prefer thicker gauges or exclusively control-focused tension setups
PU400 Technology saturates thousands of multifilaments with polyurethane to achieve 400% elasticity, aiming for power and comfort. A mix of Elastyl and H2C fibres, finished via a biphase process, improves tension maintenance and increases durability by about 10%.
Explosive power and comfort, with PU400 Technology
PU400 Technology packs thousands of multifilaments within a polyurethane saturation, raising elasticity to around 400% and creating a softer, more responsive string bed. The higher elasticity promotes greater rebound on contact without relying on stiffer materials.
Stronger rebound helps generate more pace on drives while the gentler response reduces harsh feedback on impacts, making prolonged play more comfortable.
Improved tension life and durability, with Elastyl and H2C fibres
A targeted mix of Elastyl fibres increases dynamic power, while H2C fibres are included to support tension maintenance. A biphase finishing process adds roughly 10% improved durability according to the product description.
Expect strings to maintain feel and tension longer and to resist wear more effectively, cutting down on how often restringing is required during regular use.
Precision and touch, with a 1.18mm gauge
The 1.18mm gauge gives a finer profile that allows more bite and contact precision with the ball. Finer gauges typically enhance feel by increasing string movement and contact sensitivity.
Players who value accuracy for drops and delicate shots will benefit from the increased touch and control offered by the thinner gauge.
