The ALU Power Rough features a textured surface to generate additional spin – ideal for baseline players who want to create power and spin with fast, full strokes. The curved surface allows for more flexible strings, which in turn provides a slightly softer feel with higher error tolerance. Roger Federer uses this string as a hybrid with natural gut.

• Rougher version of ALU Power for increased spin potential
• Wavy, textured surface for greater string flexibility
• The same performance-enhancing poly-ether-ether + aluminum formula as in ALU Power
• Often used as a hybrid with natural gut strings.
