Industry Nine iRiX Headset Cup

This headset cup is designed for frames with a 34mm head tube inner diameter and a 1.125-inch steerer tube. You should verify your frame's specific SHIS (Standardized Headset Identification System) requirements to ensure the EC34/28.6 specification matches your current setup.

While the iRiX system is designed for ease of use, you will still need a standard headset press to seat the cup into the frame securely. The 'tool-free' aspect refers to the assembly of the internal components and seals, which can be serviced or replaced without specialized shop tools.

The 440c stainless steel bearings offer superior corrosion resistance compared to standard steel bearings, which is critical for longevity in wet or muddy riding conditions. They provide a smoother, more consistent steering feel over time, even when exposed to the elements.

Yes, the silicone seals are designed to be replaceable. This allows you to maintain the integrity of the bearing system and keep contaminants out without needing to replace the entire headset assembly.

Industry Nine offers a lifetime warranty on the bearings, which covers defects in materials and workmanship. This ensures that if the bearings fail prematurely due to manufacturing issues, you are covered, providing long-term peace of mind for your steering assembly.
