Diago Grip-Wrapped Pedal Riser is the product of a year of research done by Diago on the best possible way of rising your back row of pedals. After many conversations between Diago and customers, and many different designs, this simple design was determined to be the best way of rising your pedals. This Diago pedal riser is constructed of 2mm formed steel with a black powder coat. The pedal carpet wrapping is the same as what is on your pedal board. The ultra grip keeps you from kicking your front knobs.
