    Quality Strings

    Posted by Diego Quesada Arias on Apr 18th 2023

    I have used 60X strings for many years on all of my Compound Bows. Single or mixed colors, you will have many possibilities to make your personal design. I never have a problem with my 60X strings, many bow makers (mathews) equip the bows with strings that have the problem of serving separation, with 60X you will never have this type of problem. If you want high quality, beautiful colors, and durability, get 60X.

    Bow String

    I have been shooting for over 30 plus years I have made strings and have bought strings from many different companies in my opinion I have used 60 X strings for about four years and have never experienced any servicing separation or string stretching or fraying and that’s why I’ve been using 60X Strings they seem to put a lot of effort in to building there strings
