iRiX Headset Top

The ideal companion to Industry Nine A35 and A318 stems, offering unparalleled customization options for your cockpit upgrades.

Meticulously machined, anodized, and laser-etched in Asheville, NC USA, using premium 7075 aluminium sourced locally, the iRiX bearing cups, top covers, and top caps exude durability and style. With a wide range of sizes and an extensive palette of 11 vibrant colours, there's an iRiX to perfectly complement any bike build.

Industry Nine designed the iRiX with serviceability and bearing longevity in mind. By incorporating features like split crown races and top cover compression rings, installation and removal become effortless, requiring no tools. Choose from two available top cover heights to achieve your desired fit and aesthetic. Moreover, the top covers feature an integrated adjustable shim stacking function, allowing you to achieve optimal headtube clearance in IS applications. To ensure your bearings remain pristine, the crown race and top cover come equipped with removable and replaceable silicone lip seals, effectively shielding the sealed bearings from contaminants.

At the heart of the iRiX lies industry-leading 440c stainless steel bearings, renowned for their smoothness and durability. Backed by a lifetime warranty, these bearings guarantee a consistently smooth ride, even after countless turns on the road.

Top and bottom cups are available separately, allowing the iRiX headsets to fit almost any frame and fork combination.
