Can't offer you much in the way of a product review as I have no intention of crash testing them

$85 per set from Dan Kyle Racing (831-394-1330)

The sliders, unlike some of the flashier styles out there on the current market are actually designed not to stand out & attract attention away from the bike.  They are supposed to be functional, not stylish & their tapered design makes them much less of an eye sore than all the other brands I have seen. They are made from Delrin (a low friction material that inherently lends itself well to impact absorption & abrasion resistance.)

Some of these new fangled sliders you see advertised made from Carbon fiber & Aluminum are nothing but gimmicks as the carbon is going to destroy itself on impact & aluminum will transmit the impact straight through to the frame you are trying to protect...
