Cane Creek Headset Upper Assembly

This is the Standardized Headset Identification System code. IS41 indicates an integrated headset for a 41mm head tube inner diameter, and 28.6 refers to the 1-1/8 inch steerer tube diameter it is designed to fit.

This specific part is the top assembly only, designed for a 1-1/8 inch straight steerer tube. If you have a tapered fork, you will need to ensure your frame's head tube and lower headset assembly are compatible with the larger 1.5-inch crown race.

No, this is a top-only assembly. It includes the top cover, compression ring, and the upper sealed bearing, but it does not include the lower crown race required for the bottom of the fork.

You must measure your head tube's inner diameter to confirm it is 41.1mm. This headset is specifically for integrated frames where the bearings drop directly into the head tube without external cups.

The headset uses high-quality sealed cartridge bearings. While they are designed to resist the elements and last a long time, they are generally considered a 'replace rather than service' component once they begin to feel gritty or loose.
