These Cyclo ProGuard Backing Plates now features permanently adhered high quality dense hook material. 3M no longer makes the double sided foam pads so these are the backing plates you will need for the single sided pads we stock. This provides a much better mating hook and much more area of hook material. The color of the cyclo pro pad holder plate is white so you can tell it is the new and improved version. Low profile for improved control and a non-marking bumper for safe operation. The advanced design still allows for faster pad centering, and is perfect for quick and easy pad changes
