Donic Bluegrip Rubbers

DONIC’s max+ rotation and max+ catapult series: a tacky, Chinese-style topsheet for maximum rotation on a blue tension sponge with a powerful catapult. The harder C versions give topspin an even higher arc and more speed; the J versions combine the pimples of the Bluestar A with the sponge and geometry of the Bluegrip C; the slightly softer S versions use a medium-pore sponge.

Sponge hardness as DONIC gives it: C2 55°, J1 55°, J2 52.5°, J3 50°, S1 45°, S2 42.5°.

Inside the rubber

Fine-pore sponge on the C2 and the J1, J2 and J3: outstanding dynamics and a harder feel, so topspins fly flatter and straighter.

Medium-pore sponge on the S1 and S2: between the large-pore and fine-pore sponges in its effect.

FDC-Touch, DONIC’s answer to the plastic ball: a tacky, very grippy Chinese-style topsheet for maximum rotation on topspins and slices, on the blue tension sponge for a powerful catapult, strong dynamics and a high ball arc.

Full tension: the speed-glue effect built in to the maximum, as in almost all of DONIC’s newer rubbers.
