We were getting a demand for tubes that had a better look and would help prevent bridle wear from friction on lower spreaders. So we brought back a sanded smooth finish tube that was similar to our original Black Diamond THP series tubes that were different colors. We decided to do the same finish with no colors. They have a very hard clear-coat paint that makes them very smooth. The tubes are the same tubes as our standard 3PT's, 5PT's and 7PT's. The only difference is we 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.
We also have just started producing a new larger diameter tube that is going to be called the Black Diamond Nitro. We developed this tube in cooperation with Ken McNeill of Blue Moon Kites. Ken wanted a tube that was stiffer than our 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 our 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. We may also clear coat tubes for spreaders. It's one of the stiffest tube I have ever had at 15 grams.
