Introducing the thinnest version of ISOSPEED Black Fire! This 1.20mm co-poly not only has impressive spin-potential, but it offers great feel and above average comfort for a control string. Black Fire comes pre-stretched for better tension maintenance. It also benefits from special additives and Liquid Wax technology, both of which are designed to reduce frictional wear. The result is a co-polyester that not only lasts longer but offers greater string snapback (think spin). 

Offers more spin-potential but slightly less durability than the thicker 1.25mm and 1.30mm versions.
