Joola is releasing five new rubbers (sometime this year). Dynaryz Inferno seems to have their latest "Kinetic tension surface" technology, and has a maximum speed rating. Seems to be an update/upgrade of the Dynaryz ACC/AGR. Dynaryz ZGX seems to be an update/upgrade of Dynaryz ZGR.
Three new rubbers are included in Joola's new Tronix series. Based on their prices, the Tronixes are likely to be replacing the Rhyzens as the mid-tier product lines. The Tronix ACC and CMD have the giga-cell sponge (versus the hyber bounce sponge of Dynaryz Inferno and ZGX); to me it implies that the Tronixes are slightly softer. The Tronix ZGR is probably an update/upgrade of Rhyzen ZGR, and it has the balance sponge instead of the giga-cell sponge. It is interesting to see that the Tronix ZGR has a higher spin rating than the Dynaryz ZGX, although, how much can you trust manufacturer ratings?
One key information missing is of course, which of them will come with new colours? For that we can go to the ITTF website:
So it seems that Joola have decided that their top-tier rubbers will get purple, their mid-tier rubbers will get blue, and their tacky rubbers will get nothing It is intriguing to see that Rhyzen ZGX is registered with the ITTF before any of the Tronix, but it is not included in the latest booklet. Maybe Joola has a change of plan.
