When original valves are not available anymore, original valves are in bad quality, or we can not find exact valves, we have the right to use our own replacement valves, without prior notice. We guarantee proper functionality of the bladders where we had to replace original valves with our own or replacement ones. Click here to read why.

We custom make all replacement bladders under official blueprints, authorized from brands, on per-order basis only. A return fee applies on all our custom bladders in case you've ordered wrong ones. We advise you to contact us prior buy in case you are not sure which one to buy.

There might be differences between original blueprints and the factory installed bladders.  Due to nature of the workmanship or welding processes there may be some standard shape and welding derivations from original blueprint valve centre positions.

From experiences we found that factory bladders can be made too tightly compared to outer skin of the kite, so that we have the right to make the bladder slightly longer and wider compared to original factory bladder or blueprint, but no more than 30mm in width and 50cm in lenght for leading edge bladder and 20mm in width and 25cm in length for strut bladders total compared to blueprint design. Knowing that, we can extend one pump valve positions accordingly.

We constantly update our bladder database to match factory bladders. But we are not responsible if original bladder blueprint measures are made too big by brand compared to factory bladders. In such case we can help by installing the bladders into the kite, customer needs to send to and pick up the gear at Dr.Tuba repair loft.

We may advise or ask customer for the measures check to minimize all unclarities with the bladder blueprints. We are not responsible in any way if the customer did not take the measures correctly or sent us wrong measures, or ordered bladder for wrong model year.
