Short answer: Coco Gauff endorses the Head Boom MP, but plays a pro stock frame designated PT339.2, built on an older Head Speed MP mold with a softer graphite layup. She strings a full bed of Luxilon Alu Power 1.25 at around 53 lbs.
The frame she really plays
Gauff's racquet is a PT339.2, a pro stock mold based on an older Speed MP layout. The distinguishing feature is the layup rather than the shape: it is a softer, more flexible build than the current retail frames, which suits a player who takes the ball early and needs the frame to absorb pace rather than amplify it.
She endorses the Boom MP, so that is the racquet that appears in her photos and the one Head markets alongside her. The mold underneath is a different generation of frame entirely.
Published specs
- Head size: 100 sq in
- String pattern: 16x19
- Base mold: older Head Speed MP, softer layup
String and tension
Full bed of Luxilon Alu Power in the 1.25 gauge, silver, at roughly 53 lbs. Reports put her between 53 and 55 depending on court speed and weather.
This is the most copyable setup on our whole pro list. Alu Power at 53 in a 100 sq in frame with an open pattern is genuinely a sane club setup, not a tour-only number. If you are a strong 4.0 or above with a full swing, you could play this exact string bed and it would make sense.
What the setup link loads, and why
Two notes, and we would rather name them than let you assume.
The racquet is currently sold out. The link loads the Boom MP, and every grip size is gone at the moment. We have left the page and the link up because the specs and the string advice are still useful, and because more are on the way. If you want one, email or call the shop and we will tell you what is coming and when.
The string is a substitution. Her string is plain Alu Power 1.25 and we are out of it. The link loads Alu Power Rough instead, the textured version of the same string. It plays slightly firmer with a bit more bite and slightly less comfort. Close, not identical.
What you can actually buy
The Boom MP is the retail frame she endorses, and it is a reasonable landing spot for the kind of player drawn to her game: fast, athletic, hitting with margin. It is a more forgiving and more powerful frame than her pro stock, which is worth knowing rather than worth avoiding. Most players need help from the racquet. She does not.
If you want the softer feel her pro stock has, the Boom line is already built around comfort, so you are closer than you would be chasing a Speed Pro.
Should you play this setup?
The string and tension, yes, if you swing fully. This is one of the few tour setups that translates almost directly, and you can order that string bed for whatever racquet you already own.
The frame, yes if you want a comfortable, powerful 100 sq in racquet with an open pattern. If you already generate plenty of pace and need control instead, look at the Speed line.
