The Ronbus Refoam R4 is a 14mm hybrid-shaped paddle built for hands battles at the kitchen line. The Refoam core gives one of the lowest swing weights on the market (106) without feeling hollow, making it an elite choice for reactive counter-punchers.
The Verdict
A hands-battle weapon with crisp pop.
This was the paddle I kept grabbing during long drilling sessions because it's just so easy on the arm. After thorough on-court evaluation, the Ronbus Refoam R4 landed in the solid mid-tier of the paddles we tested in 2026.
If you're comparing it against other foam-core paddles, it's one of several great foam core paddles we've played this year.

Performance Scores
On-Court Feel
The R4 plays incredibly fast. Drives have good snap, but the real magic happens in fire-fights at the net. The low swing weight lets you flick speed-ups with very little wrist fatigue, and the reactive face allows lightning-quick counters. The 14mm core means the soft game asks for more focus — catch a dink off the edges and the paddle torques slightly more than a 16mm Ripple R2 would.
Performance & Testing
The Ronbus Refoam R4 went through our standard on-court protocol - drills, rec play, and at least one tournament match. Scores reflect consensus feedback, not a single reviewer's opinion.
Grit & Durability
Raw carbon face provides solid initial bite. The foam-injected core dampens the harsh vibration that often plagues 14mm paddles, and the build feels structurally clean throughout. Grit retention has been consistent across drilling sessions.
Who It's For
Hands-first doubles players, reset specialists, and anyone with a counter-punching style at the net. Skip if you play singles or rely on plow-through baseline power.
Pros & Cons
Pros
- Blazing hand speed (106 swing weight)
- Crisp pop on volleys and speed-ups
- Refoam core dampens harsh vibration
- Strong value with RC3Q2082 (~$179, sale pricing may vary)
Cons
- Smaller sweet spot than the 16mm Ripple R2
- Lacks heavy plow-through for baseline singles
- 5.3" handle is short for full two-handed backhands
- 14mm core feels more reactive than 16mm control paddles
Bottom Line
A lightning-fast weapon that rewards speed and placement over raw power.
If your game is built around the kitchen line, the Refoam R4 is one of the most reactive paddles you can buy at this price.
