They are designed to minimize damage to the front forks in a low-side. The slider pucks are made of UHMW-PE (ultra high molecular weight polyethylene), a tough plastic with good strength, wear resistance and dimensional stability. It is more dimensionally stable than Nylon and used in many industrial ball bearing and friction reducing applications. The insert inside the slider is made of aluminum for strength. Rest assured that you are getting the best material commercially available. The frame sliders that you will receive will most likely be the ones pictured above. However, due to constant improvement, the frame sliders can sometimes vary slightly from those in the picture.
