Short answer: Daniil Medvedev plays a Tecnifibre T-Fight 305 with an 18x19 pattern, strung with a full bed of Tecnifibre Razor Soft at 21 kg, roughly 47 lbs. That is one of the lowest tensions in the top of the men's game.
The frame
Medvedev is on the heavier, control-oriented end of the T-Fight line. The 305 designation refers to unstrung weight in grams, and the 18x19 pattern is denser than the 16x19 most of the tour plays. Dense pattern plus higher static weight is a classic flat-hitter's configuration, and Medvedev is one of the flattest ball strikers at the top of the sport.

The tension is the story
47 lbs in a full poly bed is remarkable at this level, and it is the single most interesting number across these pages. Sinner strings the same category of string 14 lbs tighter.
The reason is the whole setup working together. A dense 18x19 pattern is inherently low-powered and controlled, so Medvedev can afford to drop tension without losing the ball long. The looser bed gives him depth and comfort back, and lets the strings move more, which helps a flat hitter find spin when he needs it. Tight strings in a dense pattern would be punishing to play and would take away everything the frame already provides.
He has experimented with natural gut hybrids over the years, as most players do, and has come back to the full bed of Razor Soft. It has stayed stable through 2026.
What you can actually buy
The T-Fight 305S and Razor Soft are both in stock, so this setup is reproducible almost exactly. The link on this page loads the frame with Razor Soft at 47 lbs already selected.
Razor Soft is worth knowing on its own merits. It is one of the more arm-friendly polyesters available, which is part of why it works at a low tension without turning into a trampoline.
Should you play this setup?
This is the rare pro tension a club player can copy outright. If anything, 47 lbs is a sensible starting point for most recreational players in a full poly bed, and it is where a lot of arm problems get solved.
The frame is a different matter. An 18x19 pattern at 305 g unstrung is demanding, and it gives you very little free power. It suits players who drive through the ball flat and generate their own pace. If you rely on spin and shape, the 16x19 T-Fight is the better door into the line.
