follow sitefollow url This is the first commercially available racquet that did not require a stringing machine to re-string it! This racquet did, however, require a lot of string and much patience. Let me say, straight away, that this (was) is a great idea! The execution was an issue, however.

Super Cheap Xanaxsee url The concept is a diagonal pattern that originates from an aluminum block that is only visible through the top of the grip opening. Into this block the ends of the string were inserted then the block is pulled into a position, by a screw thread, that achieves the string bed stiffness you want at any given time. On this one you may be able to see the red lines indicating the highest and lowest string bed stiffness I wanted to use.
