Blue Steel 1.28mm / 16, developed with Marcos Giron.

Marcos Giron

Developed with Marcos Giron

“The Blue Steel 1.28 mm I developed with Pro Stringer is the best string on tour, and trust me, I've tried many. The feel and spin is second to none, as well as the durability. With the snap-back, it gives a consistent response on every shot, and my whole game is now built on it.”

How to choose your gauge

Gauge is the string’s thickness in millimetres, with the US gauge beside it (for example 1.25mm / 17L). A smaller millimetre number means a thinner string.

Thinner gauge

More spin and bite.

1.20mm / 17L · 1.23mm / 17L

Thicker gauge

1.25mm / 17L · 1.28mm / 16 · 1.30mm / 16

Feel the difference

The shape changes the response.

    I thought I was set on Alu power until I tried silver bullet

    I thought I was set on Alu power until I tried silver bullet. SB has great spin, plenty of power and is the most comfortable poly I’ve tried. Excited to try blue steel as a full bed and also the hybrid they suggest. Great customer service.

    I have tried several stringing machines

    I have tried several stringing machines. Finally I tried the Pro Stringer String Machine and I am extremely satisfied. It is great and easy to travel with. I use it in combination with the Blue Steel 1,23 string and a Yonex Ezone 98. I have found an exceptional combo that suits me. I can only recommend the stringing machine and the Blue Steel string. Keep it up!
