voodootech chassis

The Patented Sprung Voodootech Chassis has Progressive Independent Suspension, meaning each wheel has its own independent suspension. All four wheels move separately in the frame, the spring action gets stiffer as more pressure is applied.


sharper turns

They work just like high-end racing suspension on cars and motorcycles, only much simpler. These frames are the first time a suspension of this type has ever been used on anything in the world.

Better Starts – Feels Like Ice
With Toe Digging In

As your weight moves forward or backward, you keep your balance much better because the suspension absorbs the weight transfer and keeps more wheels on the ground. As you push off, you go through the toe, from four, to three, to two wheels. The energy is stored in the polyurethane springs and then released, shooting you forward!

Increased Mobility

When you turn, your weight shifts to the center of your legs, and your turn goes from four wheels down to two, so that the turning radius is much shorter and quicker than with a conventional frame.

Little Transition From Ice to Roller

“Sprungs feel just like skating on ice” Stefan Demopoulos; 2015 NCAA D1 Champion Providence College

For roller hockey players, they are the best performing frames they’ve ever used, by far. For ice hockey players, Sprung Frames are instantly familiar, because they duplicate the action and performance of ice hockey blades, making it much easier to make the transition from ice to roller hockey, and back to ice. There really is very little difference between ice and roller hockey with these frames.

Great for Off Ice Training

 ” When I am home in the summer, playing roller hockey or off ice training I only use Sprung frames because they feel so much like ice and allow for a full extension in my stride”  Alec McCrea, Cornell U.

Our biggest growth area is among the skaters that play both roller and ice hockey or do off ice training.

Sprung suspension allows you to have a long smooth stride like ice instead of a shortened stride with a traditional roller frame.


Sprung Frame Technology

How do you make excellent even better?

There are quite a few important differences between the old and the new models. The first is a redesign of the rocker arms and frame in the pivot pin area. We widened the cross-section, to decrease the side leverage applied to the rocker arms by the wheels when taking off and turning hard. Doing this allowed us to add material in critical high-stress areas. It also widened the spring contact area of the rocker compare-W-Springsarm and the spring. This increased the resistance of the spring, making the ride firmer, with better stability and front to rear balance.

We also added material to the center section of the frame to lessen lateral torque, or twisting. Knowing we would be using the same hardware on the medium and large sizes, we went ahead and increased the diameter of the pivot pin, too.

Basically, we upgraded the medium frame to accommodate the 325 Lb. plus skaters that wear a size 10 or less. Except for the hardware, the large frame is even beefier where we thought it might need it.

Tests of our most recent model have proven the chassis is practically indestructible and can take impacts that would totally destroy an aluminum chassis.

Sprung frames not only increase your performance in roller but they make the transition from ice to roller seamless. Sprung frames makes you feel like you never left the ice rink.

I have never skated on an inline skate that felt so much like ice. My overall game has improved because I no longer feel a large difference between my ice and inline skates.

Sprung Frames eliminate the transition from ice to roller and back to ice. With these frames I can just concentrate on playing. No more skate worries!

Last year I played for Team USA and we won the Gold Medal.I used sprung frames because they allow for quicker starts, tighter turns, and more stability when stopping.

I chose “Sprung frames” because no other frame has ever felt as close to ice skating as the Sprung frame has. It was amazing how much more agile I felt with the Sprung Frames.
