Bullpadel HACK 04 2026 Padel Racket

The Bullpadel Hack 04 26 is a diamond-shaped racket from Bullpadel's Hack range, built for players who want to accelerate the ball and close out points quickly. The diamond mold puts more mass toward the head, so shots carry extra pop on smashes and overheads, with less forgiveness off-center than a rounder shape. Players who want the same core technology with a lower, more even balance can look at the Hack 04 Hybrid instead.

A channel runs around the entire frame, Bullpadel's Total Channel, cutting air resistance through the swing while adding torsional stability and stiffness so more of that swing speed carries through into the hit. Air React Channel extends the same channel through the racket's core rather than stopping at the frame edge, which Bullpadel says smooths airflow and speeds up acceleration. The TriCore heart underneath uses thicker internal vectors than earlier Hack models, aimed at cutting vibration while adding power and stability.

The hitting face is TriCarbon 18K, a carbon fibre Bullpadel builds specifically for the Hack line: 18,000 ultra-fine filaments woven in three directions, lighter and more elastic in the layup than the brand's 12K or 3K carbon, for faster acceleration and snap-back after contact. The MultiEva core sits underneath as three EVA layers at different densities. The two outer layers use firmer foam for explosive power on the hit, and a softer inner layer absorbs shock on slower, more delicate shots.

A rough 3D Grain texture, laid out in concentric circles across the face, is meant to hold the ball longer at contact and generate more spin on groundstrokes and touch shots near the net. The same concentric pattern shows up in the Smart Holes across the face, spreading flex more evenly and widening the sweet spot without softening the frame elsewhere.

Vibration control comes from three places working together. Ease Vibe dampeners sit in four holes around the frame, tested at Madrid's Polytechnic University to absorb up to 49% of impact vibration. A Vibradrive elastomer runs the length of the handle to catch off-center hits. Hesacore adds a honeycomb-textured grip underneath, shaped to spread contact across the hand and cut strain on longer sessions.

Four Custom Weight slots sit at the top of the frame. Loading additional 3g gel plates adds up to 22g and shifts the balance by as much as 1cm, so the head weight can be tuned up or down as your game changes. Given how much of the Hack 04 26's feel depends on that carbon face staying intact, a frame protector is worth adding if you play regularly on outdoor courts with concrete walls.
