FSA Headset Spacers

These spacers are designed specifically for threadless forks with a standard 1-1/8 inch steerer tube, which corresponds to an inner diameter of 28.6 mm. They will not fit tapered forks with different dimensions or threaded quill stems.

Aluminum spacers offer a robust, reliable fit that won't crack under the pressure of the stem bolts, which can sometimes happen with carbon fiber if over-tightened. They provide a secure, consistent interface for your headset assembly while remaining lightweight.

Yes, you can mix them as long as the inner diameter matches your 1-1/8 inch steerer tube. However, ensure the outer diameter of your existing spacers is similar to the FSA spacers for a clean, flush look against your stem.

The kit is quite comprehensive, including a mix of 3mm, 5mm, 10mm, and 20mm spacers. This variety allows for fine-tuning your handlebar height in small increments, making it easy to find your ideal riding position.

You will need a set of hex keys to loosen your stem bolts and top cap. The installation process is straightforward, but remember that you will need to re-tension your headset properly after adjusting the spacer stack to ensure safe steering.
