Short answer: Jannik Sinner endorses the Head Speed MP, but the frame he actually plays is a pro stock mold called the TGT 301.4, painted to look like the retail Speed. He strings it with Head Hawk Touch 1.30 at roughly 60 to 62 lbs.
The frame he really plays
Sinner's racquet is a Head TGT 301.4, built on the older Graphene Touch Speed MP mold from around 2016. Head has kept producing that mold for him even as the retail Speed line moved through several redesigns. He has stayed with it for the layup and the feel, not the cosmetics, which is why the paint changes every year and the racquet underneath does not.
This is normal at the top of the game rather than unusual. Most players find a mold that suits them early, then keep it for a decade while the marketing catalogue moves on without them.
Published specs
- Head size: 100 sq in (645 cm²)
- String pattern: 16x19 open
- Strung weight: around 325 g
- Balance: around 33.3 cm, roughly 4 points head light
- Swingweight: reported around 340
Treat the weight and swingweight numbers as reported rather than measured. Tour specs get discussed publicly but rarely confirmed, and small customizations change them match to match.
String and tension
Sinner uses Head Hawk Touch in a 1.30 gauge, strung tight at 60 to 62 lbs. That is a firm setup by any standard, and it is the single most instructive thing on this page.
A tension that high only works because of how fast he swings. Racquet head speed is what turns a stiff string bed into depth and spin. Without it, a 60 lb poly bed feels dead, the ball lands short, and your arm absorbs everything the strings do not. If you want to try his string, start in the high 40s or low 50s and work up from there.
What you can actually buy
The retail equivalent is the Head Speed MP. It shares the 100 sq in head and the 16x19 pattern, so the shape of the game it encourages is the same: a fast, flat-hitting frame that still lets you find spin when you need it. What it does not share is the layup or the tour weight. Retail comes in near 300 g strung, roughly 25 g lighter than his.
A note on what the setup link loads. It points to the 2026 Speed MP, which is the current retail model and the one we have on the shelf. At the moment it is only available in the 4 3/8 (#3) grip. The Speed MP Legend, the black cosmetic you may have seen, is the same frame family in a different paint job and is sold out across every size. If you need a different grip, contact us and we will tell you what is coming in.
That 25 g gap is closeable with lead tape and a silicone-filled handle if you want to chase it. It is also a genuinely bad idea for most players, because tour static weight is built for tour conditioning. If you want to explore it, that is a conversation worth having with a scale in front of you rather than a blog post.
Should you play this setup?
The string is worth trying. Hawk Touch is a firm, control-oriented poly with good tension maintenance, and playing it at a sane tension tells you a lot about whether you want that character in your bag.
The tension is not worth copying. The frame is worth demoing if you like a fast, low-powered 100 sq in racquet and you generate your own pace. If you need help from the frame, look at the Boom line instead.

Frame designation and mold history are widely reported by racquet specialists including TennisNerd and TennisCompanion. Head Hawk Touch and the tension range are from published gear coverage and Sinner's own interviews. String, tension, and grip choices on tour change through a season, so treat this as current rather than permanent.
