rocket
Power and spin, no compromise.
String Project Rocket is a single string designed with soft polyester treated with alpha-olefin and refined with liquid wax.
The unique production process consisting of several heatings make it flexible with a very fast ability of getting back to its position together with a highly-gripping surface.
It offers a very satisfying snapback, a perfect match between power and spin.

On-court performance
Its characteristics made it a very lively and energetic tennis string which allows to exploit the intensity of push and rotation with no obstacles and a great power’s supply, that’s also the reason of its name, Rocket.
The feeling of impact is evident and offers a feedback strictly linked to the ball. It suits both a non professional audience, because of the easy push, and a more professional one who looks for tennis string with a great ball way out and excellent ability to generate rotations.
Like the rest of the selection, Rocket is an Arm friendly single string.

Production Processes
Spring Load
This technology allows molecules’ chains to twitch several times resulting a loss of minimal tension and, above all, keeping a higher feature’s steadiness.
Multiple Heating
“Heating treatments” remove internal stress and align string’s potential irregularities. Moreover, they make strings more flexible and elastic.
Liquid Wax
The string is perfected with a wax layer. This treatment extends the duration substantially reducing the wear and making stringing easier.
Low Friction
String’s Friction’s decrease offers: diminished strings’ motion, greater potential spin due to greater snap back and a lasting duration.
