Sheet updated September 2026
The F-One Bladder S1 Strike V6 QuadX 2026 is the replacement bladder for your F-One Strike V6 QuadX wing's strut. This original F-One part is available in all nine sizes of the 2026 Strike V6 QuadX, from 2 to 6 m². Each bladder is designed for a specific model, year, and size. This means it will only fit the strut of your Strike V6 QuadX, matching your wing's size. A strut that no longer holds pressure doesn't mean your wing is done for; you can simply re-bladder it.

- Easy repair: You can replace the bladder at home with a little patience and talc, no need for a specialized workshop.

DETAILED DESCRIPTION
When to change a strut bladder
If your strut slowly deflates while the Leading Edge holds pressure, or if it remains soft after inflation, or you hear an audible leak at a weld or the valve, the bladder is the culprit. For a small perforation in the material, a patch might last a season. If the leak is at a weld or near the valve, replacement is the only lasting repair. This S1 bladder is specifically for the strut of the F-One Strike V6 QuadX 2026.
How to replace it properly
Deflate your wing, open the strut zipper, and carefully remove the old bladder. Make sure to note the direction and valve position. Lightly talc the new bladder, then insert it without twisting. Inflate it slightly to ensure it unfolds without creases, then close the zipper. Leave your wing inflated overnight before your next session. Choose your wing size in the selector. If you're unsure about your Strike's model year, please call us before ordering.
