Babolat RPM Blast 18 is built for players who want maximum spin and bite, with a very direct, connected response from the stringbed.
The ultra-thin 18 gauge allows the string to dig into the ball more aggressively, producing exceptional spin potential and enhanced ball pocketing. Compared to thicker gauges, RPM Blast 18 feels livelier and more responsive, especially on full, fast swings. The trade-off is durability: this is one of the shortest-lasting gauges in the RPM Blast lineup, particularly for heavy hitters.
On court, RPM Blast delivers the firm, controlled feel that aggressive baseliners expect from a performance polyester. It rewards fast swing speeds with heavy spin, predictable trajectory, and confidence to swing out. The thinner gauge adds touch and responsiveness, but it does not soften the string into a comfort option.
Like all stiff polyester strings, RPM Blast 18 will feel significantly firmer than multifilament or synthetic gut and will lose tension over time. It’s best suited for players who restring regularly and prioritize performance over comfort or longevity.
