Industry Nine iRiX Headset ZS Top

iRiX is a composite of “Iris” the Greek goddess and personification of the rainbow, and the Roman numeral IX. We feel this name embodies the core DNA of Industry Nine. iRiX accompanies our A35 and A318 stems bringing riders top of the line, fully customizable cockpit upgrades. iRiX bearing cups, top covers and top caps are machined, anodized and laser-etched using US-sourced 7075 aluminium in Asheville, NC USA. Available in every common modern size and 11 lustrous colours, there is an iRiX to complement any build.
Ease of service and promoting bearing life are the core design benchmarks we sought to accomplish when bringing iRiX to life. Features such as split crown races and top cover compression rings allow for an easy tool free installation and removal. Two available top cover heights allow the rider to hone their perfect fit or aesthetic. The top covers also boast an integrated adjustable shim stacking function to dial in the ideal headtube clearance on IS applications. To keep the grit and grime at bay, the crown race and top cover employ removable and replaceable silicone lip seals to keep the sealed bearings contaminant-free. iRiX uses industryleading 440c Stainless Steel bearings with a lifetime warranty to keep your turns as smooth as on day one.
