Pro-Flex is the unique ferrule design featured on all Grays premium carbon fibre badminton rackets.

The ferrule has been designed to provide lateral stability whilst allowing the maximum possible shaft flex during shots.

This provides significantly increased shaft ‘spring’, response and power for shot-making.

Pro-Flex is featured on: Airfoil Ultima, Airfoil Lite, Airfoil Elite, Airfoil Titanium, Airfoil Superlite
