How to inflate a Jim Bradley Speed Ball Bladder

1. Unzip using a piece of wire (I use a paperclip to unlock zip allowing it to open)
2. Use a pump with a needle (wet the end so it slides into valve)
3. Remove needle and use wire to assist in zipping back up

To ensure you order the correct size of bladder to fit your ball,measure the length of the bladder after it has been deflated.Please note that an old bladder can stretch a few centimeters over the years.

Measuring Your Bladder:
When the bladders are not inflated they measure from top to base

(valve to tip)

25cm = 20cm inflates to a 25cm
