About
The Rhapsody KC24 is the signature string of competition player Keiran Cooper and ZipLine’s best-selling polyester string for competitive use. Built on the PH22 foundation but with two additional thread strands and tweaked torsion to match Cooper’s tension preferences — the result is a slightly thicker feel than PH22, holds tension better, and lasts at least twice as long. Originally developed to complement the SF Yoyos Cadence. Available in neon yellow/white, neon pink/white, neon green/white, neon orange/white, and White, plus the limited Scales Edition (green, sold out). The KC24 is on its final production run — ZipLine has announced it is being retired after current stock sells through.
