The Ultrasprint blade looks to take on the competition and better it in every way. That includes using better steel, brilliance polishing, a perfect bend, better bend retention and some awesome graphics to complete the look. All at an unbelievable price.
The Ultrasprint uses a high end Japanese steel that has the following properties:
Generally, to keep costs down, short track blade manufacturers batch grind the steel quickly. The heat from this process warps the steel and makes bending the blades a difficult process. The Ultrasprint is ground slowly with highly specialized ginding wheels to avoid excess heat. This slow process creates a perfectly straight piece of steel without warping.
After grinding, a normal short track blade is inserted into the tube for gluing. Before gluing the Ultrasprint undergoes a specialized polishing process called 'brilliance polishing'. This gives the steel a very highly polished finish for better glide.
When the steel is glued into the slot in the tube, there is a gap between the steel and the tube to allow room for the glue. This gap allows the steel to warp. The Ultrasprint is glued in a jig that holds the blade in the tube while the glue dries. Each blade takes 8 hours for the glue to set so it is an extremely slow process but the end result is a perfect blade.
Aluminum tubes do not like to be bent. They always spring back to the straight position. To solve this problem, we have two solutions:
|Tube Material||6061 T6|
|Cup Material||Aluminum 7075 T6|
|Length||12", 13", 14", 14.5", 15", 15.5", 16", 16.5", 17"|
