## Donnay Formula 100 Hexacore

The Donnay Formula 100 Hexacore is the “bad” twin of the Pentacore.

From the Pentacore it shares most of the features but is distinguished by a higher stiffness (60 ra not strung) that makes the Hexacore more “competitive” than the twin.

Like the Pentacore, also Hexacore has a shaft full of polyurethane foam type Xenecorecharacterized by a 6-chamber structure (hence the name Hexacore) able to combine lightness, strength and vibration absorption in a single structure of incredible flexibility.
