Grey Spring Sponge X is applied to Glayzer 09C. Strokes with a stable trajectory are made possible, while combining powerful heavy spin with ease of over-the-table techniques at a high level. It is thanks to the combination of a friction top sheet that provides the High Tension effect and Spring Sponge X with a hardness at 42 degrees. The rubber provides players of wider ranging standards the pleasure of executing top spin strokes with heavy spin, unique to a friction High Tension rubber, as well as decisive counter-attacking play on the table.
