Hard Sponge Rubbers

The Rasanter C48 is built around counterspin: a 48° hard sponge with ENERGY CELL technology under the new C geometry.

For the perfect counterspin

• You rely on the highest quality in serve and return, persistently pressuring your opponent with spins and counterspins.
• Break with conventions, use the strengths of the ENERGY CELL technology: more power and quality in your strokes, high dynamics and longer ball contact feel.
• The ENERGY CELL sponge with its highly elastic cell structure ensures an extremely dynamic energy transfer for all topspin variations.
• Use the catapult and the above-average optimal hitting zone of the 48° hard sponge to add extra persistency to your game.
• With the newly developed C geometry you gain control over your opponent's spin with help of the Counterspin Damper.

The Rasanter C53 is built around counterspin: a 53° hard sponge with ENERGY CELL technology under the new C geometry.

For the perfect counterspin

• You dominate the game over the table and take every chance to score with a spin or counterspin.
• Break with conventions, use the strengths of the ENERGY CELL technology: more power and quality in your strokes, high dynamics and longer ball contact feel.
• The ENERGY CELL sponge with its highly elastic cell structure ensures an extremely dynamic energy transfer for all topspin variations.
• The 53° hard sponge sets the tone in open rallies: power, stability, precision.

What's So Special About These New Rubbers?

• RASANTER is the most elaborate and complex rubber development ever undertaken in Germany.
• The goal was to develop a future-oriented rubber technology that allows all ambitious and technically skilled players to overcome the physical disadvantages of the 40+ ball.
• RASANTER's topsheet compensates for the rotational disadvantages of the 40+ ball, while the denser, ultra-thick sponge increases the catapult effect and compensates for the lower speed of the cell free ball.

Rasant means fast in German, and Rasanter, of course, means faster – a hint of what these rubbers promise, although the performance advantage goes far beyond just being faster. The problem they set out to solve is the 40+ poly ball. It's been almost 3 years since the changeover, and these balls are now the standard in all sanctioned tournaments.

On average the 40+ ball is about 0.5 mm larger in diameter than the celluloid 40 ball that preceded it, and the poly material is slicker and smoother than celluloid. Together those two characteristics mean a loss of spin and speed when identical force is applied.

Table tennis manufacturers have been trying to make up for that loss ever since the switchover, and andro has now done so with the Rasanter series.

But What Exactly Makes These New Rubbers So Much Better?

The topsheet comes first. It has been thinned down significantly by andro engineers, to only 1.7 mm thick, and this extremely thin profile combined with a new pimple geometry gives a larger contact area, for a significant spin gain even at low impact speeds.

Rasanter offers two topsheet versions, V (for Velocity) and R (for Rotation), which differ in pimple geometry: the V version has smaller pimples spaced farther apart, maximizing the catapult effect of the sponge, while the fatter, more closely arranged pimples of the R version maximize the contact area with the ball and allow for stronger surface tension.

Surface grip has been enhanced too. This is still a grippy European-style topsheet, not a super-sticky Chinese-style one, with a glossy finish and superior grip to other European-style rubbers. Underneath, the sponge developed for Rasanter has a smaller cell structure than all other Tensor sponges, which produces a bigger catapult effect and a noticeable speed increase.

And because the topsheet is thinner, the sponge layer can be thicker: the new Ultramax sponge is a luxuriously thick 2.3 mm, the thickest available. A smaller cell structure and a denser, thicker sponge mean more power potential.

The sponge comes in a variety of densities to suit virtually all attacking and all-round playing styles: 42 or 47 hardness for the V version, and 37, 42, 47, or 50 for the R version. 37 is considered soft and is favored by players wanting to enhance the spin and control aspects of the rubber.

42 is a medium sponge with more speed than 37 that retains excellent feel and control. 47 is medium hard, for players who want the higher speed and extra power of a hard sponge with more control than the 50, and 50 is a hard sponge used by players with well-developed strokes who strike the ball with a lot of force and emphasize power in their games.

Together, the 2 topsheets and 4 sponges are a marvel of table tennis engineering and make it possible to ideally match one of these 6 rubbers to your playing style.

Rasanter R53 puts a 53 ° ENERGY CELL sponge under the R surface, for fast and hard topspins.

• Your game is powered by maximum spin and high dynamics. You want the point. By all means.
• Break with conventions, use the strengths of the andro ENERGY CELL technology: more power with hard topspins and game openings on backspin, high dynamics and longer ball contact time to be felt.
• The andro ENERGY CELL sponge with highly elastic cell structure ensures an extremely dynamic energy transfer, especially for fast and hard topspins.
• The 53 ° sponge provides immediate feedback on ideal ball contact. You will be surprised how soft 53 ° can feel like.
• The R rubber surface for maximum rotation gains additively more impact through the ENERGY CELL sponge.

A rubber for aggressive offensive players that play close to the table and like to hit the ball hard: very quick, accurate, and with an excellent feel. Technology: spin-optimised, medium-hard, high-end rubber.

THE FUTURE IS ALREADY HERE: versions V1 and R1 of the BlueGrip were already a revolution – the best of both worlds in one rubber! Now DONIC is taking this development one step further. With the BlueGrip C1 and C2, DONIC has added two versions to this series that outshine everything that has come before them.

The following also applies to these two versions: the DONIC BlueGrip has a tacky, Chinese-style topsheet, along with a sponge with a powerful catapult effect and incredible dynamic properties, the likes of which are only seen in rubbers from Japan or Germany. But there is more – these dynamic properties have now been increased even further.

With a sponge hardness of 60°, the C1 version gives the ball an even greater arc when playing topspin strokes and provides even more speed, while the C2 has a slightly softer sponge and subtle differences in the pimple geometry, all of which provides further support for the softer playing feel.

The C1 is a forehand rubber for uncompromising topspin players looking to gain an advantage when serving and returning serves. Very hard! Maximum dynamics and a heavily curved ball arc when playing topspin strokes, incredibly grippy.

Technology: Full tension sponge, tacky topsheet. Heaviest (90 g) and hardest sponge (60°) in the BlueGrip series.

• Surface: sticky-elastic
• DONIC technology: FD3 Technology

The C1 version, with a sponge hardness of 60°, gives the ball an even greater arc when playing topspin strokes and provides even more speed. The C2 has a slightly softer sponge and subtle differences in the pimple geometry, all of which supports the softer playing feel: it is slightly softer and significantly lighter than the C1, with values of 55° and 80 g respectively.

For uncompromising offensive players that rely on speed and spin. Powerful catapult effect, incredibly spinny.
