Introducing the new UNO single strand, made with  our   NEW   FLX    - a Next-Gen  UHMWPE fiber -
With a diameter of just 0.007”, UNO.88 is an ultralight, thin, and highly durable thread, developed as a versatile solution for tuning, reinforcement, and maintenance of bowstrings. 

Engineered for high-precision applications, it can be used to protect high-friction contact points, reinforce existing servings, or serve as a base serving, allowing color combinations to function as a progressive wear indicator. Its round profile ensures smooth, even winding with a winder, and once applied, it slightly flattens, improving adhesion to the string for more  efficient protection. 

UNO.66 enables fine-tuning of center serving diameter for optimal nock fit, securing the peep sight, and preventing direct contact between peep and string fibers. It is also ideal as a serving material for loops on recurve and compound bowstrings, providing the necessary flexibility without compromising structural strength. 

Maximum protection. Total precision. No limits.

UNO serving threads are supplied in reusable reels made of sturdy polymer, containing approximately 120 meters.
Like all our threads and servings, the UNO are Made in Spain.
