Luxilon 4g Rough 12.2 M Tennis Single String

4G Rough 125 is a textured version of 4G that displays more string flex, which generates a greater spin potential and softer feel. There is also an increased ball bite and softer feel to go along with maximum tension maintenance for durability. By denting the string while it is still soft, Luxilon maintains the structural integrity and benefits of 4G string. With 30% greater tension maintenance, players using 4G Rough 125 can play better, longer. Additionally, the entire composition of this string was designed to help players reach the next level, where it´s molecular chains are strategically aligned to minimize tension loss over time and it´s poly-ether-ether materials enhance strength and flexibility. On top of its high performance properties, the quality of these strings are unmatched by others. Not even extreme weather conditions, such as rain and humidity, will affect the playability.Specifications:- Gauge: 17- Length Set: 40 ft / 12.2 m
