Shadow gave the tried and true SOD pegs a makeover! Introducing the SOD Welterweight Peg Systems. The Welterweight features the same heat treated and butted cro-mo core as the original SOD peg, but now with an improved nylon composite sleeve material, so that it lasts longer and still slides fast. Both styles use the same sleeve, so replacements (sold separately) are easy to stock. SOD – The most advanced peg systems on the market.
