F-ONE Bladder S1 - Swing V5

Genuine F-ONE bladder designed for the centre strut (S1), the inflatable tube that joins the leading edge to the trailing edge of the F-ONE Swing V5 wing. Inside the strut sleeve, it is the part that holds the air and keeps the strut rigid; F-ONE identifies it in its spare parts catalogue as S1. When the original bladder loses air or is damaged, replacing it returns the gear to its factory condition.

Frequently asked questions

How do I know which bladder I need?

You need three details: model and version (Swing V5), size, and bladder position (S1 strut). The model and size are usually printed on the wing; the old bladder usually has them printed on it too. If in doubt, send us a photo.

What should I check when replacing it?

Check the condition of the valve and of any previous patch, 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 gentle first inflation so it settles into place before reaching riding pressure.
