SG Ultra

If you're looking for a string that just works without breaking the bank or your arm, the Diadem SG Ultra is worth a serious look. It's a synthetic gut string built with a unique construction that resists fraying over time, so you get more playing hours out of it than you might expect at this price point. It's the kind of string you can string up and forget about — in the best possible way.

The soft nylon core is really the heart of what makes the SG Ultra special. It gives the string a forgiving, comfortable feel that's easy on the arm, even during those longer sessions where you're throwing everything at the ball. That low stiffness means you can swing freely without worrying too much about shots flying long — the string helps bring the ball back into the court naturally.

The SG Ultra comes in two gauges — 16 (1.30mm) for a bit more durability, and 17 (1.25mm) if you want a touch more feel and pop. Both are available in black or natural, and each set gives you a generous 40 feet of string, which is plenty for a full job or a hybrid setup.

This string really shines for beginners and intermediate players who want something reliable, comfortable, and easy to play with. It's also a smart choice as a cross string in a hybrid setup, pairing nicely with a stiffer poly in the mains to balance out the power and control equation.
