Isospeed Black Fire 1.25mm 12m Set


The ISOSPEED Black Fire  is a polyester string with excellent control and surprisingly good playing comfort. The Black Fire has already been pre-stretched for better tension stability. It also benefits from special additives and Liquid Wax technology, which are designed to reduce friction-related wear. The result is a co-polyester string that not only lasts longer, but also gives you a bigger snapback effect for more spin.
