Bullpadel Hack 05 27

The Bullpadel Hack 05 27 keeps almost every number from last year's Hack 04 26. Same diamond shape. Same 365 to 375 g. Same MultiEVA core, same 38 mm profile, same 522 cm2 head. If you know the Hack line, you know what this is: Paquito Navarro's attacking racket, built for players who end points rather than construct them. What is new in 2027 is mostly on the label, and that is worth saying plainly before you pay for a new season's racket.

Tricarbon 18K out, 18K carbon in: a rename or a rebuild

The face changed from Tricarbon 18K on the Hack 04 26 to 18K carbon on the Hack 05 27. The product page at Pādel Nuestro still describes the new model with Tricarbon 18K faces, which makes the rename look like exactly that: a rename. Nothing in the listed specs shows a measured change in material or layup.

What does that mean on court? An 18K carbon face is stiff, and stiff faces give you a firmer, more direct hit. You feel the ball less, but you get pace back when you swing hard. Bullpadel describes the hitting feel as medium-hard, and that fits the spec sheet. Do not expect the new name to transform the racket. Expect last year's racket with a cleaner badge.

High balance only: the Medium option disappears from the label

The Hack 04 26 carried a balance label of High, Medium, with 260 mm listed by one retailer. The Hack 05 27 is listed simply as High, and no balance in millimetres is published for it. A changed label is a changed label, not a measured change. Maybe Bullpadel settled on one balance point, maybe the listing is just less detailed. You cannot tell from the outside.

What you can tell is what a high balance does. Weight sits toward the head, so the racket swings heavy and hits hard. It also means slower reactions at the net and more work for your wrist on defence. That is the deal with every Hack, and this one is no exception.

365 to 375 g, diamond, 38 mm: the attacking core that did not move

The parts that define how a Hack plays stayed identical. The weight runs 365 to 375 g. That is heavy. Combined with the diamond shape and high balance, the whole spec sheet points one way: power first, everything else second.

The MultiEVA core has a medium density, and Bullpadel claims it adapts its response to the intensity of the impact. Treat that as the brand's claim, but a medium-density core does soften the stiff carbon a little. The rough 3D surface returns for spin on bandejas and viboras, renamed from 3D Grain but described the same way: 3D and rough.

Custom Weight, rough 3D surface: the tuning Bullpadel lists

The Custom Weight system is still there, letting you add or remove small weights to shift the balance and total weight. On a head-heavy diamond this matters more than on most rackets. Pull weight out of the head and you buy back some maneuverability; add it and the smash gets heavier. It will not turn the Hack into a control racket, but it lets you nudge it toward your arm's tolerance.

Bullpadel's product page also names HackCore, AirPower, SmartHoles, EasyVibe, Vibradrive and Hesacore as part of the construction. These are the brand's own names for its technologies, not measured specs, so treat them as claims until someone tests the racket.

No balance in millimetres, no court test yet: what you cannot check

Two gaps deserve honesty. First, the balance in millimetres is not published anywhere for this model. You know it is high; you do not know how high. Second, as of now no independent reviewer has published a court test of the Hack 05 27. Everything you read here comes from the spec sheet and the brand's own marketing.

The product page pushes a concept Bullpadel calls dynamic power: the idea that the racket converts your own movement speed into shot power. That is marketing language, not a measurement. The measurable truth is simpler. Stiff faces, high balance, heavy weight, small sweet spot. A demanding racket for players who already hit hard.

Hack 05 27, Hack 05 Hybrid 27 or Vertex 04 25: picking your Bullpadel diamond

Bullpadel sells two siblings in the same 2027 family. The Hack 05 Comfort 27 swaps the carbon faces for Fibrix and drops to 360 to 370 g. It rates medium on comfort: same attacking idea, kinder arm. The Hack 05 Hybrid 27 keeps the 18K carbon but moves to a hybrid shape with low balance, rating high on control. Same family, different answer.

The rival diamond in the catalogue is the Bullpadel Vertex 04 25, with 12K carbon faces and Juan Tello's name on it. The Hack is the stiffer, more extreme option. And if you are hesitating between this and last year, the comparison with the Hack 04 26 shows how little moved. If you find the Hack 04 26 still listed, you are looking at nearly the same racket.
