The Babolat RPM Rough Tennis String 12m Yellow is a textured polyester monofilament built for heavy topspin and firm control. With a 16 gauge (1.30mm) thickness and a distinctive rough surface texture, this Babolat tennis string bites the ball harder at impact, helping players generate sharper spin on forehands, backhands, and kick serves. The Babolat RPM Rough 12m length delivers enough string for one full racket restring, while the durable polyester build resists notching through extended play. Cut from the full reel in a bright Yellow colorway, this is a strong pick for intermediate to advanced players who build their game around aggressive topspin and controlled baseline power.
