The Tau 90 is the face of a new era! It´s the first Triskate used for freestyle skating. Bigger wheels make sitting tricks easier and allow you to lift your heel and toe higher. The management of the balance on one wheel is easier and you are also able to get a higher speed for your tricks. The Tau 90 offers different rockering options which a regular 4 wheel skate can´t offer. You are enabled to rocker just one wheel or two wheels on your skates. You can even rocker your left and right skate in a different way to optimize your freestyle skating!

The Trinity carbon shell sets a new standard in the freeskating world. It´s the first carbon shell made by compression moulding like you know it from carbon parts made for the formula 1 cars or carbon frames and parts of high end race bikes. This manufacturing process enables us to reduce the weight of the shell by making the shell thinner but still increasing the overall strength compared with carbon shells made by regular wet lamination. Another benefit of the compression moulding process is the possibility to create shell designs with sharp contours which you only know from injected composite parts. The shell of the Tau skate is not symmetric as most of the shells you can find for skates. Our shell is perfectly shaped and anatomically built for left and right feet in order to create a better fitting and performance of the skate. The bottom of the shell is ventilated to keep your feet fresh.

The cuff was designed with support in mind. It´s made of a special composite compound that is super stiff thanks to the 15% fiberglass, which was mixed into the material. An integrated arch stiffens up the side to provide perfect lateral support. The strap passes through a channel to keep it in place and to avoid slipping and flipping.

The patented Powerslide Katana rocker aluminium frame is a top of the line frame made of high end 6061 aircraft aluminium. It is based on a double voided construction. The extra ribs between the wheels increase the stiffness and help to lower the weight. The frame is very well balanced and super stiff thanks to its special TRINITY 3-point mounting construction and general distribution of the forces through 3 mounting points. The Katana frame gives you the opportunity to rocker the center and rear wheel or just one of them. A laser printed arrow on the head of the axle indicates if the wheel is rockerd up or down.
