Elena Rybakina String Tension & Setup
One string in the Yonex kit, the VCORE 100 frame, and no published tension.
By String Tension AI · Published · Research checked
This is a source-based equipment profile, not an official Elena Rybakina page. It reports what Yonex lists for Elena, compares that listing with our catalog row, and does not fill the missing tension with an estimate.
Yonex’s athlete page lists Elena Rybakina with the Yonex VCORE 100 racquet and Yonex POLYTOUR FIRE 125 string. The kit lists one string. That fits a full bed of POLYTOUR FIRE, but the page does not confirm what goes in the crosses. The kit lists the 1.25 mm version of POLYTOUR FIRE. Yonex states no string tension, and this profile does not show one as her setting: a product listing identifies equipment, not a stringing-machine reference setting. Our catalog row lists POLYTOUR FIRE 1.25 in the mains with no cross reported, matching the kit’s string and gauge. Its racquet record listed a VCORE 98 until October 3, 2026, when we changed it to the VCORE 100 named in the kit.

What strings does Elena Rybakina use?
Yonex POLYTOUR FIRE 125, as listed on Yonex’s athlete page.
The kit lists one string. That fits a full bed of POLYTOUR FIRE, but the page does not confirm what goes in the crosses. The kit lists the 1.25 mm version of POLYTOUR FIRE.
What string tension does Elena Rybakina use?
Yonex does not state a tension. A product listing identifies equipment; it is not a stringing-machine reference setting, a later stringbed measurement or a personal specification.
The Elena Rybakina row in the pro string setups table carries a tension from Racket Fit, accessed by our catalog on 2026-07-16. We have not reconfirmed it for this profile, so it is not repeated here as her current setting.
How this profile compares with our pro setups table
Our catalog row lists POLYTOUR FIRE 1.25 in the mains with no cross reported, matching the kit’s string and gauge. Its racquet record listed a VCORE 98 until October 3, 2026, when we changed it to the VCORE 100 named in the kit.

What racquet does Elena Rybakina use?
Yonex’s athlete page lists the Yonex VCORE 100. A manufacturer listing names the model; it does not establish the weight, balance or customization of a professional’s own frame.
Should an app reading match a pro’s machine setting?
No. Even where a professional’s reference setting is published, a later app reading estimates installed stringbed tension, a different physical state. For Elena there is no confirmed setting at all. Read the reference setting and stringbed estimate distinction, then compare readings with your own fresh-string baseline.
Track your own setup instead of copying a pro
A professional’s equipment is context. Your useful comparison comes from your own racquet history. In String Tension AI, save your frame, string, gauge and reference tension, measure a fresh-string baseline and repeat under similar conditions.
Follow the repeatable measurement workflow and watch tension loss alongside feel and hours played. This does not imply that Elena Rybakina uses or endorses String Tension AI.
What this means for a club player
This page does not show a confirmed main reference setting, so there is no professional number to compare against, and you do not need one. Your starting point comes from your own racquet and the string construction you choose.
- Look up your frame’s published range in the racquet tension range table.
- Choose your string construction and playing objective in the starting-tension calculator.
- After restringing, take a fresh-string baseline reading and judge later readings by relative change, alongside feel and hours played.
Elena Rybakina string setup FAQ
What strings does Elena Rybakina use?
Yonex’s athlete page lists Yonex POLYTOUR FIRE 125. The kit lists one string. That fits a full bed of POLYTOUR FIRE, but the page does not confirm what goes in the crosses.
What string tension does Elena Rybakina use?
Yonex does not state one, and this profile does not show a tension as her setting. The tension in our catalog row comes from an older secondary source that we have not reconfirmed.
What gauge does Elena Rybakina use?
The kit lists the 1.25 mm version of POLYTOUR FIRE.
Is Elena’s setup a full bed or a hybrid?
The kit lists one string. That fits a full bed of POLYTOUR FIRE, but the page does not confirm what goes in the crosses.
What racquet does Elena Rybakina use?
Yonex lists the Yonex VCORE 100. The listing names the model, not the specifications of a professional’s own frame.
How does this profile compare with the pro setups table?
Our catalog row lists POLYTOUR FIRE 1.25 in the mains with no cross reported, matching the kit’s string and gauge. Its racquet record listed a VCORE 98 until October 3, 2026, when we changed it to the VCORE 100 named in the kit.
Should I copy Elena’s setup?
There is no confirmed tension to copy, and a professional’s frame, swing and stringing support differ from yours. Start from your own racquet’s published range and the string construction you choose.
What app reading should match Elena’s setup?
None. There is no confirmed machine setting to use as a target, and a later app reading estimates installed stringbed tension, a different quantity. Compare your readings with your own fresh-string baseline instead.
Sources and methodology
The manufacturer source establishes the listed equipment. It does not state a tension, assign strings to mains and crosses, or give personal frame specifications, so this profile leaves those fields open rather than estimating them. The catalog row is compared field by field. The manufacturer listing is treated as the stronger identification: on October 3, 2026, catalog strings, gauges and racquet records that differed from it were changed to match. Tension, string direction and any gauge the manufacturer does not state still come from the secondary source. See the parent catalog methodology.
The manufacturer source was checked on 2026-10-03. The secondary source shows the date our catalog accessed it; it was not rechecked for this profile. Publication dates are shown only when supplied by the source; an access date is not a claim that an undated page was published that day. No personal racquet was inspected for this profile.
