What the page says
- Choose a racket made for your level of physical strength and your play style.
- Check that there are no cracks or other irregularities on the shaft, frame and grip.
- Hold the grip in one hand and the frame in the other; flex and twist the shaft to look for damage.
- Check the grip for wear. The page warns that a worn-out grip can make the racket fly out of your hand and injure you or others.
- Worn-out grommets can damage strings and let them break easily.
A one-minute routine
- Look along the frame and shaft in good light for cracks.
- Hold and flex the shaft gently, as described above.
- Press the grip and look for slipping, tearing or smooth, shiny areas.
- Run a finger over the grommets for rough or cracked edges.
- Keep a damaged racket aside and have it checked before playing.
Limits
The page gives no replacement interval for grips or grommets. If a grip feels worn, see the guides on replacing the grip.
