João Fonseca Racket Setup: What Does He Actually Use?

Quick answer: Yonex officially lists João Fonseca with the VCORE 98 and PolyTour Force in 2026. The more complicated question is the racket underneath the current cosmetic. Public gear reporting and visible drill-pattern evidence point to a customized VCORE 98-family player frame with a 16x20 pattern, but the exact mold generation is not factory-confirmed and should not be presented as settled fact.

If you arrived here after commenting JOÃO on one of our posts, this is the evidence-based breakdown.

What Yonex officially confirms

Yonex's current João Fonseca athlete page lists two key pieces of equipment:

• Racket: Yonex VCORE 98
• String: Yonex PolyTour Force 130

Yonex also listed Fonseca with VCORE 98 / PolyTour Force in its 2026 tournament equipment coverage. That makes the current public racket family and string association high-confidence information.

The retail VCORE 98 is not the whole story

The current retail VCORE 98 uses a 16x19 pattern. Fonseca's player frame has repeatedly been associated with a denser 16x20 drill pattern, which immediately tells us that “VCORE 98” does not necessarily mean an untouched retail frame.

This is normal at tour level. A player can carry the current commercial cosmetic while keeping a familiar mold, layup, drill pattern or customized specification underneath. If that distinction is new to you, start with what is a pro stock tennis racket.

Which exact VCORE mold does João Fonseca use?

This is where we need to be precise.

Some public gear reports identify the underlying racket as an older VCORE 98 platform, often linked to the 2021 generation, with a 16x20 pattern. The 16x20 detail is visually and publicly well established; the exact generation and mold attribution is less certain.

We therefore label it this way:

Customized VCORE 98-family player frame, 16x20 — reported. Exact mold generation — unconfirmed.

That wording is more accurate than treating “VCORE 98 2021 mold” as a factory-confirmed specification.

João Fonseca's 2026 string: PolyTour Force

The string story has changed over time. Older Yonex material associated Fonseca with PolyTour Strike. In 2026, Yonex now officially lists PolyTour Force, matching the bright red string visible in his current setup.

That makes PolyTour Force the strongest current answer rather than an image-based guess.

What tension does João Fonseca use?

A public stringing report from Halle 2026 listed Fonseca at approximately 48/46 lb with PolyTour Force.

That should be treated as a tournament-specific reference, not a permanent specification. Professional players adjust tension with surface, conditions, balls, temperature and preference. Other public reports have placed him slightly higher at other times.

So the useful answer is not “João always strings at 48/46.” It is: 48/46 lb was a reported 2026 tournament setup and his working tension can change.

Why a 16x20 VCORE makes sense for his game

Fonseca creates enormous racket-head speed, especially on the forehand. A slightly denser pattern can give a powerful hitter a more controlled launch and a more predictable response while retaining access to spin.

That does not mean every aggressive player should use 16x20. The rest of the specification, meaning swingweight, balance, flex, string stiffness and tension, determines how the racket actually behaves. See tennis racket specs explained for what each of those changes.

Retail VCORE 98 vs João's player frame

The retail VCORE 98 is the closest public starting point, because it shares the VCORE 98 family identity, the head-size direction and the modern spin-control concept. It is not an exact replica of his tour racket and nobody should sell it as one.

If you want to get closer to the tour side of the family rather than the shelf version, IP-coded VCORE pro stock frames do come through Europe. They are individually measured units rather than catalogue models, so they are chosen on the numbers of that exact frame. Browse the current pro stock rackets, and read how we verify pro stock and rare gear before you buy any of them, from us or anyone else.

Should you copy João Fonseca's exact setup?

Usually not.

Professional specifications are built around a player's timing, strength, contact point and daily workload. A 16x20 pro stock frame with a firm polyester feels very different in recreational hands. We talk people out of exact pro replicas most weeks.

The useful question is not “How do I copy João?” but “Which part of his setup logic solves my problem?”

• Too much launch: a more controlled string before a denser frame. Toroline Caviar or Super Toro keep the ball down.
• Not enough spin: check string movement before changing frames. A shaped main with a slick cross, such as O-Toro x Snapper, adds more spin than a new racket will.
• Low stability: measure swingweight and balance before adding mass.
• Harsh feel: do not assume a professional's stiff polyester suits you. Drop the cross gauge first.

FAQ

What racket does João Fonseca use?

Yonex officially lists the VCORE 98. His tour frame is widely reported to be a customized VCORE 98-family 16x20 rather than an untouched retail 16x19.

Does João Fonseca use the 2026 retail VCORE 98?

He uses the current VCORE cosmetic publicly, but the underlying player frame and drill pattern differ from the standard retail specification.

What strings does João Fonseca use?

Yonex officially lists PolyTour Force in 2026.

What tension does João Fonseca use?

A Halle 2026 report listed 48/46 lb. Treat that as a tournament reference, not a fixed year-round number.

Can you buy a VCORE pro stock frame?

IP-coded VCORE pro stock units do reach the European market. They are not replicas of any named player's racket and should be judged on the measured specification of the individual frame.
