Racket's rubber testing

Hello coach,

How can we test our racket's rubber if it still good or if we should replace it?

Hi Naji,

A simple test is to rub your finger across the rubber and see if it has grip on it.  Or you can hold a ball and rub it against the rubber and see the same thing.

The other things is to look at the rubber and see if you can see the pimples coming through on the rubber.

Also if you are starting to feel that when you play your shots you are not generating as much spin or speed then it may also be time to change.  As a guide, rubbers will last around 100 hours of playing time.
