Design
OPTIMAL PRESSURE HOLD: Longer time between 2 inflations thanks to a bladder containing 80% butyl. Butyl is the rubber with the greatest airtightness.
BETTER WATER ADHERENCE:
Our ball benefits from 2 changes compared with the WP500 ball:
- wider channels for a better grip.
- A more adherent rubber component called "soft tacky".
