RPM Blast Rough Color:Black 17g strengthening the frame in keyPrice shown includes stringing fee! RPM Rough is the textured version of RPM Blast, one of the most popular co polys ever made. Like the standard RPM Blast, this string is a co polymer monofilament with an octagonal shape and a special cross linked silicone coating.
