The Babolat RPM Blast is one of the most iconic polyester strings in modern tennis. Produced by Babolat, RPM Blast is best known for its exceptional spin potential and control, making it a favorite among aggressive baseline players.
Designed for players who swing fast and rely heavily on topspin, RPM Blast allows hitters to attack the ball confidently while keeping their shots inside the court. Its combination of spin, control, and durability has made it one of the most widely used polyester strings on the professional tour.

Babolat RPM Blast Performance
RPM Blast is widely known for its spin-friendly performance and ability to help players generate heavy topspin. Its firm polyester construction allows aggressive players to swing freely without sacrificing control.
Comfort & Feel
Comfort sits on the firmer side of the polyester spectrum. The string bed feels crisp and controlled, but players who prefer a soft or plush feel may find it somewhat stiff. As with most polyester strings, RPM Blast performs best for players who are used to firmer setups.
Players with arm sensitivity may prefer softer alternatives such as multifilament or natural gut strings.
Power & Control
Power is moderate and largely dependent on the player’s swing speed. RPM Blast does not provide much free power, but it rewards fast swings with a controlled and predictable response.
Control is one of the string’s standout qualities. Players can swing aggressively while maintaining excellent accuracy, allowing them to dictate points and keep the ball inside the lines.
Spin Potential
Spin is where RPM Blast truly shines. The string’s textured surface increases friction with the ball, helping players generate heavy topspin and sharp angles. This makes it particularly effective for players who rely on spin to control rallies and push opponents behind the baseline.
The strong snap-back effect of the polyester also contributes to increased spin production.
Durability & Tension Maintenance
Durability is another strong aspect of RPM Blast. The co-polyester construction makes it resistant to breakage and suitable for players who hit with significant pace.
However, RPM Blast is known to experience some tension loss over time, which is common among spin-focused polyester strings. As tension drops, the string may lose some of its crisp feel and control.
Pros
- Exceptional spin potential
- Outstanding control for aggressive swings
- Very durable polyester construction
- Widely trusted by competitive players
Cons
- Firm feel may reduce comfort
- Noticeable tension loss over time
Who Should Use RPM Blast?
Babolat RPM Blast is best suited for:
- Aggressive baseliners who hit with heavy topspin
- Intermediate to advanced players
- Players looking for maximum spin and control
- Players who swing fast and generate their own power
It is not recommended for beginners or players who prefer a soft, comfortable string bed.
Final Thoughts
Overall, Babolat RPM Blast remains one of the most popular polyester strings in tennis thanks to its incredible spin potential and precise control. It allows aggressive players to swing freely and generate heavy topspin without losing accuracy.
While it may not provide the comfort of softer strings and can lose tension over time, players who rely on spin and aggressive baseline play will find RPM Blast to be a highly effective and reliable option.
