Strut 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 valve(s) you want where you want by simply "peeling and sticking". Click here to find out which valves are available as U-STICK.

The strut bladders are made of high quality american made poly. All strut bladders have a reinforced head to strengthen the bladder. 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.

Strut bladders
Open the end of the bladder sleeve and measure from the very end of the strut to the very front of the strut where it attaches to the leading edge bladder sleeve. Measure along the bottom seam, this is the seam or fold that faces you when the kite is in the air flying or when it's on its back ready to be inflated.

Choose a strut 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.
