Short answer: Elena Rybakina plays a Yonex VCORE, strung with a full bed of Yonex PolyTour Fire in the 1.25 gauge at around 56 lbs.
The frame
Rybakina is on the VCORE line, Yonex's spin-oriented family, with a 16x19 pattern. The VCORE is built around an aerodynamic frame shape and a string bed geometry designed to grip and release the ball, which is the opposite design philosophy from the dense-patterned control frames elsewhere on this list.
It is an interesting pairing with her game. Rybakina hits a famously flat, heavy ball and serves as well as anyone on the WTA. A spin-oriented frame in the hands of a flat hitter gives her margin she would not otherwise have.

String and tension
PolyTour Fire at 1.25, full bed, around 56 lbs. Some reports put her closer to 26 and 25 kg with a small split between mains and crosses, so treat 56 as the centre of a narrow range rather than an exact number.
PolyTour Fire is the firmest, most control-oriented string in Yonex's PolyTour range, which is what makes this setup coherent. Spin-friendly frame, control-first string. The frame supplies the shape, the string keeps the ball in. That balance is worth understanding as a principle, because it is a more useful lesson than the specific numbers: your frame and your string should be solving different problems, not the same one twice.
What you can actually buy
The VCORE 100 and PolyTour Fire are both available, so this setup is close to directly reproducible. One note: we are down to a single set of PolyTour Fire in the 1.25 gauge. If it is gone by the time you read this, the 1.20 is the same string in a thinner gauge, with a bit more spin and less durability.
Should you play this setup?
The frame is one of the more accessible on this page. The VCORE 100 suits intermediate and advanced players who want help generating spin without giving up a lot of control.
56 lbs in a full bed of a firm poly is tight for club play. Start around 50 and go from there, or use the softer PolyTour Pro if your arm has a history.
