Adidas Metalbone Carbon 3.4 2025

Introduction

The Adidas Metalbone Carbon 3.4 is a heavy, diamond-shaped racket for advanced players who want maximum power and are willing to trade some control.

Shape & Balance

The diamond shape puts the balance toward the head, which boosts power but reduces maneuverability. You'll feel the weight in your swings, so be ready for a heavier feel.

This balance rewards players who use their whole body to swing. It's not ideal for quick, defensive reactions at the net, but it's a beast for smashes.

Grip

The grip size is standard, and the handle is comfortable for most hands. However, the head-heavy balance can add strain to your wrist and forearm over long matches.

You might notice fatigue if you play several hours, but it's manageable for experienced players used to heavy rackets.

Power & Control

With a power score of 8.4, this racket delivers real pace on aggressive shots. The stiff 6K carbon face and soft EVA core combine to give you that extra push on smashes and flat hits.

Control at 8.1 is still high, but you'll need precise technique to place shots accurately. The racket does what you tell it, but it expects you to know what you're doing.

Comfort & Speed

The soft EVA core helps absorb some shock, but the head-heavy balance means you feel the racket's mass on every shot. It's not the most comfortable for long rallies, but it's not brutally harsh either.

Maneuverability is 7.9, which is decent for a heavy racket. In quick volleys, you'll be a bit slower off the mark, but you can generate impressive whip on serves and smashes.

Materials & Durability

The frame is made of carbon fiber, which is strong and durable. The faces are 6K carbon, a high-grade material that gives a crisp response and should hold up well over time.

The EVA Soft Performance core is a softer foam that offers a comfortable feel and good bounce. Combined, these materials make a racket that feels solid and built to last, though the high weight means you need good control to avoid impact damage.

Analysis

The Metalbone Carbon 3.4 plays like a sledgehammer. With a diamond shape and 360-375g weight, it generates serious pace on smashes and hard shots. The power rating of 8.4 matches that, but the high weight and balance make it demanding—you need good technique and timing to get the most out of it.

The rebound score of 9.7 is exceptional, meaning the ball flies off the face quickly. This helps with power but can make control tricky, especially on softer touches. The control rating of 8.1 is still high, but you'll notice it's less forgiving than a rounder racket.

The sweet spot is rated at 7.8, which is solid but not huge. Off-center hits will lose power and accuracy, so this isn't a racket for casual play. Maneuverability is 7.9, which is okay for a heavy racket, but you'll feel the weight in fast exchanges.

If you're an advanced player who loves attacking and can handle a stiff, weighty frame, this could be your weapon. Beginners or those with elbow issues should look elsewhere—the lack of forgiveness and high weight will punish you.
