Pickleball Paddle Spin SoftPlex and Surface Care
Useful spin brings shape, placement and confidence to your shots. Explore how your stroke works with the paddle’s finished surface, and use clear test information to understand published spin figures.
Your stroke and contact shape the shot. The finished surface contributes to the interaction with the ball, and appropriate care helps keep it clean and ready for play. This guide explains those distinctions and how they apply to KOBO's SoftPlex surface. KOBO makes Thunder AXE, so this is brand educational content.
What spin numbers can tell you
RPM means revolutions per minute: how quickly the ball rotates. A spin result becomes useful when you also know the method, ball, paddle condition and whether the result comes from a player hitting or a controlled machine setup.
Treat an RPM number as a result under stated conditions. Compare within the same method before comparing across sources. A difference between two published figures may reflect the test setup or player rather than a meaningful product advantage.
On court, judge whether your usual topspin serve or drive produces the trajectory and depth you intend. Maximum spin is less useful if you need to force the stroke or lose control of placement.
Raw carbon and surface coatings describe different things
Carbon-fiber terminology identifies part of a paddle's construction. It does not, by itself, describe every layer that contacts the ball. Check both the underlying face material and the finished playing surface.
Thunder AXE uses a 3K carbon face with a SoftPlex coating over it. SoftPlex is the surface coating, not the carbon fiber itself. A comparison with another paddle should account for that coating rather than treating every carbon face as the same surface.
For Thunder AXE, the clearest description is a 3K carbon face with a SoftPlex surface coating. The finished surface and complete paddle construction help explain how a carbon face works with your stroke. KOBO's Thunder AXE engineering explanation describes how the surface sits within the paddle's complete construction.
Understand the measurements behind surface research
Spin output, surface texture and long-term service life answer different questions. Keeping them separate makes published research more useful.
| Measurement | What it describes |
|---|---|
| Spin rate in RPM | How quickly the ball rotates under the stated test conditions |
| Surface roughness | The texture measured at the face |
| Roughness retention | How measured texture changes during a particular wear procedure |
Pickleball Effect explains how it measures texture before and after controlled abrasion. Its research offers a useful introduction to surface testing. Roughness retention and spin retention are different measurements, and a laboratory wear procedure does not translate directly into months of play. Read the surface-testing explanation.

Explore SoftPlex as part of the Thunder AXE system
Thunder AXE pairs its SoftPlex-coated 3K carbon face with an 18mm DuroCore, Carbon Stripe Core Structure, EVA perimeter foam and thermoformed unibody construction. KOBO presents these as an integrated approach to touch, ball interaction and player feedback.
During a demo, explore familiar topspin serves, rolls and drives, alongside dinks and resets. Look for the trajectory, placement and feel you enjoy. The resulting shot depends on your technique and contact as well as the paddle.

The USA Pickleball spin test in 2026
USA Pickleball states that paddles submitted for certification beginning October 1, 2026 must measure 2,100 RPM or less under its Spin Rate Test to receive approval. It also states that certified paddles must comply with the standards that applied at certification. Read USA Pickleball's implementation announcement.
This is a certification-test threshold. A reviewer's human-hit result above 2,100 RPM does not, by itself, establish that a paddle fails that test. Do not place unlike methods on a single ranking scale.
KOBO identifies Thunder AXE Infinity with the registration name THUNDER INFINITY. The USA Pickleball entry showed Pass, an added date of March 5, 2026 and an 18mm depth when checked on October 16, 2026. For tournament planning, check the current listing and the requirements your event uses. View the registration.
How to care for the SoftPlex surface
For Thunder AXE Silver and Gold, gently wipe the face with warm water and a clean microfiber cloth, then dry it before storage. Do not use the KOBO Carbon Paddle Cleaner on either AXE version. Avoid chemical cleaners, abrasive pads, sanding, scraping or attempts to refinish the face.
A general carbon-paddle cleaning tip may not apply to a coated surface. Follow the model-specific guidance rather than assuming a cleaner is suitable because the underlying face contains carbon fiber. Read KOBO's paddle-care instructions.
Keep the paddle clean, dry and protected between sessions. If you have a question about the surface or a change in feel, KOBO support can help you choose the appropriate next step.
A practical spin comparison
Use the same ball and your normal stroke with each paddle. Begin with placement you can repeat, then add topspin while keeping a similar target. Alternate paddles so you are not comparing a warmed-up swing with your first few attempts.
Notice whether you can create the intended arc and depth, how consistently you find clean contact, and whether the same motion remains comfortable. This is a personal demo, not an RPM or durability test. A few strokes cannot establish how a surface will perform after months of use.
If you want to explore SoftPlex as part of a control-focused paddle, view the Thunder AXE Infinity 18mm. Consider the whole response, including touch and resets, alongside spin.
Common questions
Is the roughest face always the best for spin
Surface feel alone cannot establish spin output. Compare results from a consistent test method and check whether your normal stroke produces useful, repeatable shots.
How should I compare paddle surface information
Look at the finished surface, the test method and the shots you enjoy playing. Compare spin results within a consistent method, and use the manufacturer’s model-specific care guidance.
Does a smooth feeling surface mean a paddle cannot produce spin
No. How a surface feels to your hand is not a spin measurement. Evaluate the finished surface, stated test evidence and how the paddle works with your normal contact.
Can I use a carbon cleaner on Thunder AXE
No. Thunder AXE Silver and Gold require gentle cleaning with warm water and microfiber. The KOBO Carbon Paddle Cleaner is not approved for those surfaces.
