keen

A concentrate of technology, incredibly solid and reactive.

Keen is the narrowest string created by String Project. The cobalt-blue exterior hides a very narrow section, 1.18 mms and 1.13 mms, but just as strong as any other.The composition is a concentrated technological blend, a mixture of 5 different materials that make it incredibly solid and reactive after a snapback.With its sensitive and powerful qualities, Keen increases the ability for spinning during the game, creating a natural connection with the ball and multiplied effect of power and rotation.

Its narrow calibre gives the right feel to tame thrust and to perceive the ball at its best when on the head of the racket, with a notable natural control over the direction of the shot.Slender but enduring, Keen yields very well on control-based rackets and manages to enhance and simplify the player’s performance when in use.Soft and elastic it also manages to protect the arm on impact.

production processes

Multiple Heating

"Heat treatments" eliminate internal stresses and smooth out any irregularities in the rope. It also makes the strings more flexible and elastic.

Liquid Wax

Once manufacture is complete the string is refined with a layer of wax. This layer simplifies stringing the racquet and significantly extends the life of the string itself by reducing wear.

Spring Load

This technology enables the molecule chains of a monofile string to contract again, resulting in minimal tension loss and increased stability of playing properties as well as increased arm protection.

Low Friction

The reduction in rope friction offers: reduced string movement, greater potential spin thanks to greater snap back, and a longer duration.
