SpeedUp X Booster User Manual

SpeedUp X is for players who won’t give up precision, even under pressure. If you scanned the QR code on the bottle, you’ve found the booster that delivers power without losing a firm touch. If you got here through the 360TT blog, get ready to understand the technology behind the brand’s new generation of optimizers.

Unlike traditional treatments, which usually soften the sponge to gain speed, SpeedUp X takes a different path: it works on the structure of the material to generate propulsion without compromising the original firmness (stiffness) of the rubber. The result is a lethal attack with the same direct, solid response you already know, without that feeling of “excessive softness” that gets in the way of control. As a bonus, the formula also improves the glue’s grip on the sponge, helping prevent that annoying lifting at the edges of the rubber.

SpeedUp X is the opposite approach to SpeedUp Pro: while the Pro penetrates deep to make the sponge extremely elastic and pliable, the X preserves the structural firmness for solid, direct strokes. If you are looking for the middle ground between the two approaches, SpeedUp 360 is the in-between choice.

Phase 1: surgical preparation (cleaning)

Before thinking about speed, we need cleanliness. The booster has to penetrate the sponge, and layers of old glue are barriers that prevent even absorption.

• New rubbers: they usually come ready. You can skip to Phase 2.
• Used rubbers: you must remove 100% of the old glue from the sponge.

Phase 2: applying it to the sponge

With the sponge clean and free of glue, let’s start the treatment. The 60ml bottle of SpeedUp X has an applicator nozzle (no spray here) and a safety cap.

Step by step

1. Application: draw a generous “X” of SpeedUp X on the sponge, covering the whole surface well.
2. Massage: cut a small piece of the applicator sponge provided and use it to spread and rub the product in well, pressing on the rubber’s sponge to help absorption.
3. Waiting time: unlike other boosters in the line, SpeedUp X has a high-viscosity formula, which means a longer curing time. Let it work for at least 12h, but the ideal is to wait 24h per coat for a complete effect. The sponge must be dry to the touch, with no trace of oil.

How many coats? We recommend 2 coats for the ideal result: power with the firmness intact. Went past 3? Good luck. You’ll need it.

Material sensitivity

SpeedUp X has an interesting profile precisely because it does not push the sponge to a single extreme:

• Sensitive rubbers (European/Japanese): they are naturally softer already. The X helps keep them from becoming even looser, preserving response and control even with the gain in power.
• Dense rubbers (Chinese/hard sponge): if you like the natural firmness of these rubbers, the X is excellent: it adds speed without softening what already works well.

Phase 3: professional assembly

Once the treatment is done, you will notice the rubber has curved, forming a dome. The rule here is the same as with SpeedUp 360: the higher the dome, the more tensioned and faster it has become.

When the sponge is dry to the touch and shows no trace of oil, it is ready to be glued.

The official recommendation: EasyGlue Carbon

To unlock 100% of SpeedUp X’s potential, the combination is essential: the stiffness of the carbon particles in EasyGlue Carbon complements the firmness preserved by the booster treatment, creating a setup with maximum speed and absolute precision.

Since SpeedUp X reinforces the glue’s grip on the sponge, successive coats of booster can make that grip more sensitive. If you have any trouble when gluing, contact our team. We are here to help.

Now it’s your turn. Assemble your racket, go to the table and feel the explosive power without losing precision on your very first attack. Enjoy your training!

At 360TT, it’s quality by players, for players.
