Available in every common modern size and 11 lustrous colors, there is an iRiX to complement any build. Features such as split crown races and top cover compression rings allow for an easy tool free installation and removal. iRiX uses industry leading 440c Stainless Steel bearings with a lifetime warranty to keep your turns as smooth as on day one.
