Highlights
What makes this racket stand out
Diamond shape with medium balance gives junior players access to real attacking geometry without the extreme head-heaviness of the full adult Vertex line
Evalastic rubber core absorbs enough vibration to protect developing arms while still delivering the firm, direct rebound that teaches proper technique
CarbonTube frame in 100% bidirectional carbon holds the racket's shape under hard contact — no flex, no energy loss, consistent response from the first smash to the last

Our verdict
What the shape, core and construction tell us about how this racket is built to play.
The short version
The Vertex JR 25 is one of the few junior rackets that takes attacking play seriously — the diamond shape and CarbonTube frame give it genuine left-side credentials for a junior player who is learning to dominate at the net. The Evalastic core and medium balance make it physically manageable, but the unforgiving sweet spot means it will expose weak technique rather than cover for it. A junior who hasn't yet built consistent contact should look elsewhere first; one who has will find this a legitimate stepping stone toward adult-level diamond performance.
Strengths
Junior players with 2+ years of experience who are developing an attacking game and want a racket that rewards overhead power and decisive volleys
Young left-side specialists who are learning to finish points and need a diamond frame that responds honestly to good technique
Keep in mind
Junior beginners or players still building consistent groundstrokes — the diamond shape punishes off-centre hits sharply and will slow down skill development at that stage
How it's built to play
The Vertex JR 25 is Bullpadel's junior adaptation of the Juan Tello signature line — and unlike many junior rackets that simply slap a smaller logo on a beginner frame, this one preserves the core attacking identity of the adult Vertex. Diamond shape, CarbonTube construction, Evalastic core. It's a racket that asks something of the player holding it, which is exactly the point for a junior who's outgrown the forgiving stuff.
The CarbonTube frame is 100% bidirectional carbon fibre wrapping the full perimeter — that means virtually no flex at contact, with energy transferred directly into the ball rather than absorbed by the frame. For a junior racket at this price point, that's a meaningful construction choice: cheaper builds use mixed-material frames that feel hollow and give inconsistent feedback, which is the last thing a developing player needs. The Polyglass fiberglass face introduces some give back into the equation — it flexes slightly at impact, creating a mild trampoline effect that helps generate ball speed on slower swings. It's a sensible pairing: the rigid CarbonTube frame holds the shape, the Polyglass face adds a touch of forgiveness. The Evalastic rubber core sits between soft foam and hard EVA in terms of density — it cushions the strike enough to reduce vibration through a junior's arm, but its rebound elasticity is firm enough to maintain shot speed and teach the player that technique drives power, not the racket.
The medium balance is the key spec to understand here. Adult diamond rackets typically run high balance — head-heavy, demanding significant arm strength and consistent swing mechanics to control. By pulling the balance point toward the middle, Bullpadel has made the Vertex JR 25 manageable for a junior's physique without abandoning the diamond's attacking geometry. The sweet spot still lives high in the head, so the reward for a well-timed overhead or bandeja is real pace and a direct, confident sensation. Mishits off the edge, though, are punishing — the stiff CarbonTube frame doesn't smooth over poor contact the way a round fiberglass racket would. On volleys and fast exchanges at the net, the racket responds quickly given the medium balance, and the Evalastic core keeps the feel from becoming too harsh during long training sessions. This is not a racket for grinding from the baseline — it wants to be at the net, finishing.
FAQ
How does the Vertex JR 25 compare to the adult Bullpadel Vertex 04 or Vertex 05?
The main differences are balance and core. The adult Vertex models run high balance and use MultiEVA cores tuned for maximum power output — they're head-heavy and demand significant arm strength. The Vertex JR 25 uses medium balance and an Evalastic core, which is softer and more vibration-absorbent. Both share the diamond shape and CarbonTube frame, so the attacking geometry is genuine, but the JR version is physically lighter to swing and kinder on a developing arm. A junior who transitions from the JR 25 to an adult Vertex will feel the head-heavy shift immediately — it's a meaningful step up, not just a size change.
Is the Vertex JR 25 suitable for a junior who is just starting padel?
No. The diamond shape means the sweet spot sits high in the head and is relatively small — off-centre hits lose power sharply and send vibration through the frame. Beginners make off-centre contact constantly while developing their swing, and a diamond will punish every one of those mishits. A junior starting out is better served by a round or teardrop frame with a soft foam core, which keeps the ball in play more consistently and doesn't penalise imperfect technique. The Vertex JR 25 is for juniors who already hit consistently from mid-court and are ready to develop an attacking game.
What does the Evalastic core mean for a junior player's arm?
Evalastic is an elastic rubber/foam compound that sits between soft foam and hard EVA in terms of density. It absorbs more impact shock than a standard hard EVA core, which matters for juniors whose arm musculature is still developing. It won't eliminate vibration entirely — the stiff CarbonTube frame transmits some feedback through the racket regardless — but it significantly reduces the harsh resonance you'd feel from a full hard-EVA diamond. For a junior training multiple sessions per week, that cushioning effect reduces fatigue and lowers the risk of early overuse issues in the elbow.
Should I choose the Vertex JR 25 or a teardrop junior racket at a similar price?
That depends on what the junior is working on. A teardrop junior racket will have a larger, more central sweet spot and a more forgiving response across the face — it suits players still developing consistency and court positioning. The Vertex JR 25 is specifically for juniors already committed to an attacking style who want to develop overhead smashes and net finishes. If the junior plays mainly from the back of the court or hasn't yet picked a court side, a teardrop is the safer choice. If they're consistently at the net and learning to dominate on the left side, the diamond geometry of the Vertex JR 25 starts to make sense.
What does CarbonTube mean in a junior racket, and is it worth it at this price?
CarbonTube means the entire frame perimeter is wrapped in 100% bidirectional carbon fibre — no mixed materials, no fiberglass sections in the frame. That makes the structure torsionally rigid: when a ball hits the frame wall, it doesn't flex or deform, so energy transfers cleanly into the shot rather than being lost in frame movement. At this price point, many junior rackets use composite or fiberglass frame sections that feel soft and hollow under pressure. The CarbonTube construction on the Vertex JR 25 gives it a more honest, direct response — a junior with good technique will feel the difference immediately, and it builds a cleaner understanding of what a well-struck ball should feel like.
