You will already heard of the G-Sport Pleg Pegs for sure. They are Super-Lightweight, made from Heavy-Duty Plastic and have Massive Advantages over Metal Pegs. They Grind much more easily than Steel, Aluminium or Titanium on Aluminium, Brick, and Rough Concrete; plus you shouldn't get into trouble by the local police for breaking up the concrete like Metal Pegs do. They are roughly Half the Weight of a Light Steel Peg and come in your choice of 10mm or 14mm. Try them, and you'll never go back to metal Pegs.
