Silkeez Quad Trux   
"The Ride Says it All"     

Silkeez Quad Trux make skateboarding safer and smoother.
Just like the back wheels of a tour bus, Silkeez axles articulate. As the first wheel
 goes over a "bump," the bus (board) is raised only half as high as the bump. Then,
as the front wheel is past the bump, the rear wheel of the Silkeez Quad Trux crosses,
again the bus (board) is raised only half as high. Smooooooth.

Safer!! No more (or fewer) face plants or unloads. Just ride through the things
 that before would cause pain.

More stable at speed in that the inline design of each pair of wheels on the
 side of the axle creates stability and less wheel wobble that can cause loss of
 control--not a "good thing" at high speed. Get a chance to ride a demo (see below)
 and you'll be convinced.
