StringSpec
Lab-measured tennis strings
StringSpec puts the measurements of nearly 800 tennis strings inside your AI. Every string was tested on the same machine under the same protocol, so the numbers compare fairly: string bed stiffness, how much tension it loses, how much energy it returns, spin potential, ball bite, string friction and how far it stretches under load.
What you can ask

- Instructions
StringSpec: lab measurements of 791 tennis strings (stiffness, tension loss, energy return, spin potential, friction, elongation), with retail prices. Use for one named string, for two or three, when a player describes what they want (spin, comfort or arm pain, control, power, tension hold, durability, feel), and to filter or sort by brand, material, gauge, a measurement or price. Lower stiffness is softer and kinder on the arm; lower tension loss holds tension longer. Present measurements as measurements and estimates (playable life, tension advice) as estimates. Give the StringSpec url when the user wants the full page.
