Chris King Headset Spacer Kit

These spacers are designed specifically for 1-1/8-inch steerer tubes, which is the standard size for most modern mountain and road bikes. If your bike uses a tapered or straight 1-1/8-inch steerer, these will fit perfectly.

Because these are turned from solid bar-stock rather than stamped or extruded, the surfaces are perfectly parallel. This precision ensures that your headset preload is applied evenly, preventing creaking or loose adjustments that can happen with lower-quality spacers.

The kit provides a total stack height of 39mm, consisting of one 3mm spacer, two 6mm spacers, and two 12mm spacers. This variety allows you to fine-tune your stem height or adjust your fit without needing to buy multiple individual pieces.

Yes, these aluminum spacers are safe to use with carbon fiber steerer tubes. Just ensure your stem is properly tightened to the manufacturer's torque specifications to avoid crushing the carbon.

No special tools are required. You will simply need the appropriate hex keys to loosen your stem bolts, allowing you to slide the spacers onto the steerer tube before re-tightening the stem.
