Leading edge bladder blanks
All bladders used with the U-STICK bladder system are provided without valves. You choose the bladder by length and then choose the valves to match your kite's set up. You then attach the valves you want where you want by simply "peeling and sticking". Click here to find out which valves are available as U-STICK.

The leading edge bladder blanks are made of a single piece of high quality american made poly folded in half and welded on one side only. All bladders are oversized in diameter so that they never fully expand inside the sewn sleeve of the kite. This eliminates any need for the bladder to stretch allowing for longer life.

All bladder blanks are pre-talced on the inside to aid in installation and simplify their use.

Wrap around leading edge bladder
Open the ends of the bladder sleeve. Measure the leading edge/wingtip sleeve from end to end. Measure around the outside of the arc formed by your leading edge, be sure that the measuring tape runs around the outside of the elbows where your leading edge turns onto the wingtip.

Choose a leading edge bladder that measures the same length or longer than the measurement that you came up with. If you are at all unsure of your measurement, round up to the next size offered. An oversized bladder works, an undersized bladder will not work.
