Each slider is precision CNC machined from High Impact DuPont Delrin resin for superior toughness and strength. This results in reduced wear and friction and keeps them ightweight yet strong. Our sliders will not shatter or dig in when hitting the pavement. Each of our swingarm sliders comes with a solid aluminum core for added strength and durability. Do not be fooled by cheaper, smaller spools that break off easily without an aluminum core. Each slider works as a swingarm spool to use with any rear stand. This set includes two swingarm slider spools and all mounting hardware. Available in Black only
