At a glance

What the Hack 04 2026 is designed to do

Bullpadel describes the 2026 Hack around what it calls “dynamic power”: turning the speed of your swing into pace on the ball, rather than relying on a very heavy head. In practice the design brief breaks down like this:

• Attacking geometry. A diamond with weight towards the head gives leverage on smashes, viboras and flat put-aways, as long as you meet the ball high on the face.
• Aerodynamics. The new Total Channel runs round the frame and links to the Air React Channel in the heart. Bullpadel says this reduces drag and improves frame stability, which is the main change for 2026.
• A firm face with a layered core. TriCarbon 18K on the face and a three-layer MultiEva core (denser outer layers, softer centre) are meant to give pace on full swings without being completely dead on softer shots.
• Adjustable balance. CustomWeight takes up to four 3 g gel-tipped plates at the top of the frame. Bullpadel says this changes balance by up to plus or minus 1 cm. Its Hack 04 26 page also quotes “up to 22 g heavier”, which does not match four 3 g plates, so treat the 12 g figure (quoted on its Hybrid page) as the safer number.
• Vibration control. Ease Vibe dampers in four holes and the Vibradrive handle insert. Bullpadel says the dampers absorb up to 49% of impact vibration.

What the specs suggest on court

This is not a playtest. Padel Mad has not played with the Hack 04 2026. The points below are what the published specs and retailer descriptions point to, not our own on-court impressions.

• Power overhead: the diamond shape, 26.4 cm balance and a stiffness rating of 4 out of 5 point to a racket built for finishing at the net.
• Handling: Bullpadel rates manoeuvrability 3 out of 5, the same as control and sweet spot size. Expect it to feel less nimble in fast volley exchanges than a round or hybrid racket.
• Arm load: an intermediate to hard feel plus a head-heavy balance is not the obvious choice if you have elbow or shoulder trouble, despite the damping tech. The Hack 04 Comfort is the softer option in the same line.

For a hands-on view, the English-language video below walks through the 2026 Hack line, including the Hack 04.

Where to buy the Hack 04 2026 in the UK

We found three live offers on 22 October 2026:

• Amazon UK, ASIN B0FPTM52HS: about £138.79, sold by Amazon EU, only three left. The listing images match the 2026 Hack 04 colourway.
• Amazon UK, ASIN B0FS1SVHMG: about £237.14, sold by Amazon US, only two left. Same racket, a different seller and a much higher price.
• Decathlon UK: £169.99 for the Bullpadel Hack 04 26 Paquito Navarro, with delivery shown from two working days.

Bullpadel’s own site listed it at €239.99 (down from €319.99), and Decathlon UK was already listing the Hack 05 27 at £299.99. That is the main reason the Hack 04 is now well below its £305 UK RRP: it is the outgoing edition. If you want the newest model, look at the Hack 05; if you want the best value, the 2026 Hack 04 is the one to watch.

Hack 04 2026 vs Hack 04 Comfort 2026

The Hack 04 Comfort 2026 (ASIN B0FPTSYBQS) keeps the diamond shape, 38 mm profile and 26.4 cm balance, but swaps the TriCarbon 18K face for Fibrix and drops slightly to 360 to 370 g. Bullpadel rates its feel as intermediate rather than intermediate to hard, with lower power (2.5 out of 5) and stability scores. It is the Hack to look at if you like the attacking shape but want a softer, more forgiving response. It was in stock on Amazon UK on 22 October 2026 at about £151.21 from a third-party seller (Padelmarket).

Hack 04 2026 vs Hack 04 Hybrid 2026

The Hack 04 Hybrid 2026 (ASIN B0FPTTJQQV) is a different racket despite the shared name. Bullpadel lists a hybrid shape, a lower balance of about 25 cm, a larger 529 cm² surface and an 18K aluminised carbon face with an intermediate to soft feel. It scores higher for control, manoeuvrability and sweet spot (4 out of 5 each) and lower for power. Bullpadel pitches it at players who build points and counter-attack rather than smash. It was in stock on Amazon UK on 22 October 2026 at about £133.03 from Padelmarket.

Last season: Hack 04 2025

The Hack 04 25 (ASIN B0DHZJJT3S) is the previous edition. Its Amazon listing gives the same 365 to 375 g weight range, a MultiEva core and CustomWeight, but Bullpadel presents the Total Channel frame as new for 2026, so the 2025 model does not have it. It was in stock on 22 October 2026 at about £114.91, sold by Amazon EU, with only one left, so expect it to sell out soon.

Older and cheaper: Hack 03 2024

The Hack 03 24 (ASIN B0CKRZ22HT) is two editions back. Its listing describes a diamond aimed at professional and advanced players, built for maximum power. It was in stock on 22 October 2026 at about £119.00 from a third-party seller (WeProPadel). We cover it in more detail in our Bullpadel Hack 03 24 review.

Who the Hack 04 2026 suits

• Good fit: advanced and competition players with a fast swing who like to finish points at the net, and want a head-heavy diamond with adjustable balance.
• Think twice: beginners and improvers, players who rely on quick hands at the net, and anyone with arm trouble. The Hack 04 Comfort, Hack 04 Hybrid or the picks in our best intermediate padel rackets UK guide are better starting points. Our how to choose a padel racket guide explains shape and balance in more detail.

Looking after a premium racket

A carbon racket at this price is worth protecting. A frame protector reduces chips from the glass and floor (see are padel racket protectors worth it?), though it adds a few grams to an already head-heavy frame. Fresh overgrips keep the handle secure (best overgrips guide), and fresh balls help any racket play as designed (best padel balls UK). Avoid leaving it in a hot or freezing car, which is hard on any carbon frame and foam core. If you want to put the extra head weight to use, our guides to the vibora and the perfect padel smash are good next reads.

Is the Hack 04 2026 good for beginners?
No. Bullpadel rates it for professional players with an offensive style. Beginners will get on better with a lighter, lower-balance round or teardrop racket; see our beginner and intermediate guides.

The headline change for 2026 is the Total Channel round the frame, linked to the Air React Channel, plus a redesigned Smart Holes pattern. The weight range is the same.

Is there a newer Hack?
Yes. Decathlon UK was listing the Hack 05 27 at £299.99 on 22 October 2026, which is why the Hack 04 2026 is now heavily discounted.
