This RPM Blast Rough is a rougher version of RPM Blast for increased spin potential. The string offers a maximum spin thanks to its octagonal section, rough texture, and the Cross-Linked Silicone. The string also offers a unique sensation thanks to the High-density Co-PET. Made of the same material and with the same octagonal shape as RPM Blast, RPM Blast Rough has a rough texture thanks to the small Babolat logos that are imprinted into the surface of the string. Babolat RPM strings are stretched under controlled temperature in order to deliver greater durability, reduced fatigue, and consistent repulsion.
