Tennis strings built for heavy topspin
If you want more spin, the racquet matters less than the string. A polyester or co-polyester (often called "co-poly") string snaps back into position after each impact, biting the ball at contact and releasing more rotational energy than a softer string ever can. The strings in this collection are the spin specialists — Babolat RPM Blast and RPM Rough, Wilson Luxilon ALU Power, Tecnifibre Triax Razor Code, Yonex Poly Tour Pro and Dunlop Explosive Spin. Most pros and serious club players use exactly this kind of string.
How to choose
For maximum bite, look at textured polys (RPM Rough, Black Code, shaped strings). For more comfort with spin, softer polys like Babolat RPM Soft. Pair with one of our spin tennis racquets for a complete spin set-up. For stings cataloguing, see Babolat, Wilson and Tecnifibre strings.
Frequently asked questions
Why do polyester strings produce more spin?
Stiffer monofilament construction lets the strings slide and snap back rapidly on contact, gripping the ball longer and adding rotational energy.
Are spin strings hard on the arm?
Standard polys can be — they're stiffer and transmit more shock. Try softer polys (RPM Soft, X-One) or hybrid set-ups if comfort matters.
How often should I restring with poly?
Polys lose tension quickly. Most players restring every 10-15 hours of play, or sooner if the string starts to feel "dead".
What gauge gives the most spin?
Thinner gauges (17/1.25mm and 18/1.20mm) typically grip and snap more aggressively. See our 17 gauge page.
Can I use poly in a soft frame?
Yes, but consider lower tension (around 50lbs) to preserve frame comfort. Multifilament hybrids work well in flex frames like the Wilson Clash.
