Question about this product?

We're happy to help.

String of choice for Rafael Nadal, Babolat RPM Blast 15 offers more durability than the 16 gauge version and sacrifices some spin generation. This string shares the same basic construction and co-polyester composition as the popular Babolat Pro Hurricane Tour, with a few minor tweaks. The RPM Blast stays with the octagonal profile but enhances the spin generation through the use of a new dye and coating. The black color of this string makes it play slightly stiffer than the yellow Pro Hurricane Tour, while the new silicone coating is designed to allow the strings to slide across each other easier. This serves two purposes, the first is that the string can move easily, effectively allowing the stringbed to play as a more open pattern than it is. The second, of course, is to enhance durability by lessening string to string friction. Babolat's RPM Blast is a popular choice among strong baseliners seeking durability and spin to dictate the action.

Construction: Extruded co-polyester monofilament

Color: Black

Gauge: 1.35mm (15L)

Length: 660' / 200m
