• As the temperature of the ball increases, so does its bounce
• Temperature rises due to repetitive impact and force of impact: i.e. the harder the ball is hit and the longer it stays in play will result in a higher temperature and consequently a livelier bounce
• Squash balls are divided in 4 types (by Dunlop) to make the game of squash equally enjoyable for all playing levels
• It is important to choose the squash ball that matches your skill level

• Approximately 95 % of all squash balls sold are manufactured by Dunlop
• Dunlop is the official ball of Squash New Zealand and therefore the vast majority of all competitive tournament players prefer Dunlop squash balls
• Other brands are available and balls of various brands bounce differently. If playing competition, the Dunlop ball will be used.

1. Dunlop Revelation Pro XX - Two yellow dots (extra low bounce)
2. Dunlop Revelation Competition - One yellow dot (low bounce)
3. Dunlop Max Progress - No dot, 6% larger than Pro XX (medium bounce)
4. Dunlop Max - Blue, no dot, 12% larger than Pro XX (high bounce)

• Dunlop Max (high bounce) or Dunlop Max Progress (medium bounce)
• While improving, try to switch to the more demanding Revelation Competition (Dunlop, low bounce) to acquire more finesse
• Choose a bouncy enough ball so that you are able to maintain a rally

• Play either with Dunlop Revelation Competition or Dunlop Revelation Pro

Composition

• Squash balls are made of 2 pieces of extremely durable, high quality rubber compound, glued together and filled with compressed air
• Like compressed air tennis balls, they lose pressure over time

Replacing the squash ball

• A good bounce is vital to really enjoy the game, therefore balls should be replaced on a regular basis (2-3 months)
• Harder hitters need to replace balls more frequently
• Over time the ball becomes spongy and loses a lot of bounce
• Try to squeeze the ball when you buy it and see how firm it feels
  Squash balls, like tires on a car, wear and become slick. When this happens, the ball loses its original and true bounce
• Low bounce squash balls (Dunlop Revelation Pro XX) should be replaced more often than bouncier balls (Dunlop Max)
