These NTC Designs Surron and Segway foot pegs are made out of heavy duty CNC 7075 billet aluminum for durability. We designed these foot pegs to be wider so its more comfortable and will make riding easier in different terrain such as heavy duty off road riding. The OEM pegs can be slippery and don't provide much grip. Our pegs allow for more grip and improved safety. Check out the photo comparing the stock pegs to ours. These pegs are made to fit OEM and aftermarket foot peg brackets. Screws are replaceable and are made from stainless steel to prevent rusting.
