Bulletproof Cycles/Wiz Knee Pucks Sliders
Wiz Knee pucks are the best in the business. They are a hard puck that slides smoothly on any track surface and doesn't catch and pull your knee like most softer OEM pucks. In addition to the great slider material they have the option to add titanium to the pucks for sparks that look awesome in pictures! Track pucks are built up larger by about an inch, and last longer than the traditional smileys. The velcro backing is no joke, and we have never lost a puck even when catching them on the curbing.
