Alienation Illuminati Headset

The Illuminati KT is designed specifically for integrated head tubes that accept a 1.125-inch steerer tube. Before purchasing, confirm your frame uses an integrated headset system, as it will not work with press-fit or external cup head tubes.

The headset features a taller top cap design that effectively adds stack height directly into the headset assembly. This allows you to achieve a higher handlebar position without needing a tall stack of loose spacers on your steerer tube, resulting in a cleaner, more rigid front end.

These bearings are sealed, meaning they are well-protected from dirt and moisture. While they are low-maintenance, it is good practice to occasionally wipe away any grime from the seals and ensure they are lightly greased during your annual bike service.

Yes, the kit comes complete with two sealed bearings, a top cap, an alloy compression washer, and a selection of 2mm, 5mm, and 8mm spacers. You will only need basic bike tools to install it.

Absolutely. The headset is CNC machined from AL6061-T6 aluminum, which is a standard material for high-strength bicycle components. It is built to handle the stresses of daily riding while keeping the overall weight low.
