We will custom install the Bones Hardcore Bushings (soft) when building your complete skateboard.
Simply put, Bones bushings allow the skater to more easily control and maneuver the skateboard. This applies to all levels of skaters! They provide a consistent and soft resistance during a turn, while also providing a consistently stable return to center.
The Bones Website does provide a more detailed description including some videos with our buddy - pro skater Jordan Hoffart: http://bones.com/why/bushings/
