Description
Genuine F-ONE replacement bladder for the S1 strut, one of the inflatable tubes running from the leading edge to the trailing edge of the F-ONE Strike V4 CWC Aluula wing. It is the inner chamber that gives that strut its stiffness; in the F-ONE spare parts catalogue it is identified as S1. If yours is punctured, porous or burst, this part gets your gear back in action without having to replace anything else.

Frequently asked questions
How do I know which bladder I need?
Check the wing model and version (Strike V4 CWC Aluula), its size and which tube has the leak (S1 strut). The reference printed on the original bladder helps confirm it; if you can't find it, write to us with a photo.
What should I check before fitting it?
Check the condition of the valve and of any previous patches, because many leaks come from there. Clean the sand out of the inside of the sleeve, lay the bladder out without any twists and give it a first gentle inflation so it settles into place before you bring it up to riding pressure.
