Sky Shark Black Diamond Nitro Standard Tube Clear Coat 32.5"

Black Diamond Series by Sky Shark
Sky Shark was getting a demand for tubes that had a better look and slicker finish that would help prevent wear from friction.  So they brought back the original Black Diamond series tubes. They have a very hard clear-coat paint that makes them very smooth and with a sanded slick finish. The tubes are the same tubes as their standard 3PT's, 5PT's and 7PT's.  The only difference is they take grains, not grams of material off the tube very precisely.  The amount of material in weight that is taken off is replaced by the weight of the paint.

Sky Shark has started producing a new larger diameter tube that is called the Black Diamond Nitro.  Sky Shark developed this tube in cooperation with Ken McNeill of Blue Moon Kites.  Ken wanted a tube that was stiffer than the current 5PT to stop any wing chatter that comes with high wind flying and to create better all around performance.  So the new tube has a larger diameter, different taper, and is about 15 to 20% stiffer than the current 5PT.  It is also a sanded tube.  This tube can also be cut from the large end as well as the small end.  This gives you the ability to change the stiffness. The tubes may also clear coat tubes for spreaders.  It's one of the stiffest tubes at 15 grams.

The Black Diamond Nitro Standard Clear Coat is 32.5".
