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 One V2 kite. It is the inner bladder that gives that strut its rigidity; in F-ONE's spare parts catalogue it is identified as S1. It's the solution when the original bladder is losing air and patching it again is no longer worth it.

Frequently asked questions
How do I get the right bladder?
Check the kite's model and version (One V2), 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, send us a photo.
What should I check when replacing it?
Check the inflation valve and where it joins the bladder, as well as any patches you've made on the sleeve. Before inserting the new bladder, clear any sand or debris from inside the tube and position it without folds or twists; inflate it at low pressure first so it seats properly.
