Nothing beats the raw sound and feel of steel. The Animal Team Pegs measure in at 4.5 inches long for full contact. Forged, heat-treated chromoly steel for strength and smooth grinding on all surfaces. Internally butted, so they are thicker where it counts and lighter overall. Drilled for 14mm axles, with a 3/8 adaptor included.Specifications:Defined Color: Black Color: Black Material: Steel Length: 4.5 Individual or Pair?: Individual
