Diadem string at Diadem's own prices: Pro X $13.95 set · $194.95 reel. Contact us and we'll send you a payment link. All our stringing and string sales live at Mobile Racket.

A pentagonal co-poly with a livelier response than most shaped polys, so you get bite plus a bit of free power. It feels sharp fresh, settles after the first hour, then gives up some snap and tension over the next several hours. String 2 to 4 lb under your multi tension. Good for 4.0+ topspin players who find RPM Blast too dead. Softer Tecnifibre options: Ice Code or Red Code.

Best for: Spin with snap. Feel: Firm, lively. Gauge: 17. Look at the gauge on the pack before it goes in the racket.
