In stock

Luxilon 4G 16L-1.25 String Reel is a new 17 gauge co-polyester string that places an emphasis on playability and tension maintenance, without sacrificing the spin, control and durability for which Luxilon is known. Surprising comfort and longer playability than most polyester strings, thanks to proprietary improvements in string construction. Thinner 17 gauge for added playability. Convenient reel ideal for frequent stringers or hybrid use.

Advance to a new generation of string technology with Luxilon 4G 125 660 tennis string. This innovative string offers incredible durability along with the legendary power and spin that you expect from Luxilon strings. To make things even better, 4G offers enhanced comfort and 30% less tension loss than any other polyester. It is the first polyester string to be similar to natural gut in tension maintenance.

Though quite firm and durable, Luxilon 4G is loaded with playability.  Luxilon spent two years tweaking the molecular properties of 4G in order to extend the life of playability.  This is a great option for players who want all the benefits of a control string without the high tension loss and impact shock that comes with some of the first generation polys. This doesn't mean it will work for players who prefer natural gut or nylon multifilaments, but it does mean that for players with long, fast strokes Luxilon has created a very user-friendly co-poly.  Used on the pro tour by Alexandr Dolgopolov, Kei Niskikori, and Grigor Dimitrov.
