DONIC QUATTRO Formula
Incorporates Speed Gluing Effect, But Is Not Too Fast
Experts have known it for a long time: while speed gluing makes rubber faster, the dominant effect is to make the rubber softer and - at least subjectively - to produce better ball control - despite the speed-glued rubber being spinnier and faster.
By adding Formula tuning to our QUATTRO rubber, we have increased the performance, but we have limited the speed to ensure that you can easily keep the rubber under control. As a result, new QUATTRO Formula rubber incorporates all the traditional advantages of speed glue, while giving more ball control and higher precision. This makes QUATTRO Formula ideal for allround players and players who prefer good ball control.

No other rubber has ever provided such a good feeling with relatively high speed.
