The Rockboard Descender is an all-terrain skateboard ready to tear up any surface that stands in your way. Though unlike typical skateboards, the Descender’s tank-like treads provide traction on grassy slopes, pavement, wooded paths, snowy hills and more. No need to wait for a sunny day or a smooth sidewalk; skateboard enthusiasts can now take their sport off-road. Beneath the Rockboard Descender’s deck are four heavy-duty triple-wheel sets (36 wheels in total) surrounded by a rubber tread. The treads tilt both backward and forward for stability and smooth transfers between different surfaces. Never let any terrain go untraveled with the Rockboard Descender.
