Short answer: Novak Djokovic endorses the Head Speed Pro, but plays a pro stock frame designated PT346.1, painted to match. He strings a hybrid: natural gut in the mains at 27 to 28 kg, Luxilon Alu Power Rough in the crosses at 26 to 27 kg. That is roughly 59 to 62 lbs mains and 57 to 59 crosses, among the highest tensions on tour.
The frame he really plays
Djokovic's frame is a Head pro stock mold, PT346.1. It is not sold to the public and never has been. Head paints it each season to match whatever the current retail Speed Pro looks like, which is why his racquet appears to change every year while the stick underneath does not.
Worth flagging: some gear sites still list him on the PT113B. That was his earlier frame. He moved to the 346.1 mold, which carries an 18x19 pattern rather than his old 18x20, along with a slightly reduced static weight and swingweight. If you see the two designations quoted against each other, that's why.
Published specs
- Head size: 95 sq in
- String pattern: 18x19
- Length: 27.1 in, slightly longer than standard
- Strung weight: reported around 353 to 359 g
- Balance: around 32.4 cm
- Grip: Head rectangular TK57 pallet, leather grip plus two overgrips
The hybrid, and why it matters more than the tension
Djokovic runs natural gut in the mains and Alu Power Rough in the crosses, with the crosses about 1 kg looser than the mains. This is the classic tour configuration and the reason his tension numbers are misleading in isolation.
Natural gut at 60 lbs plays considerably softer than polyester at 60 lbs. The gut mains give him feel and hold the ball; the Alu Power Rough crosses supply spin and bite. Read his tension as a full poly bed and you would conclude he plays something close to unplayable. He doesn't. The hybrid is what makes that number survivable.
He also runs a deliberate tension split between mains and crosses, roughly 3 lbs. That gap lets the mains move and snap back, which is where a lot of his spin comes from.
What you can actually buy
The retail equivalent is the Head Speed Pro. It shares the general character, a control-first frame that rewards a player who supplies their own pace. It does not share the mold, the 27.1 inch length, or the tour weight.
On strings, we should be straight with you: we do not currently stock natural gut, so the full Djokovic hybrid isn't something we can build. What we can do is the crosses string on its own, Alu Power Rough, in a full bed. That is a real and common club setup, considerably cheaper, and closer to what most players should be using anyway. Natural gut is expensive, sensitive to moisture, and asks for a stringer who knows how to handle it.
Should you play this setup?
The frame is for advanced players. A 95 sq in head with an 18x19 pattern at tour weight is unforgiving, and the retail Speed Pro, while lighter, still asks a lot.
The hybrid concept is worth borrowing even if his numbers are not. Gut mains with a poly cross at something like 48 to 53 lbs gives a club player most of what he is getting: feel, spin, and a string bed that doesn't punish the arm. If gut is out of budget, a full bed of Alu Power Rough in the low 50s is the sane version.
