Zipp Headset Spacer

These spacers are designed for standard 1-1/8 inch steerer tubes, which is the most common size for modern road and mountain bikes. As long as your fork has a 28.6 mm outer diameter steerer tube, they will fit perfectly.

Carbon fiber spacers are significantly lighter than their aluminum counterparts, helping you shave a few grams off your bike's total weight. They also offer a sleek, uniform aesthetic that matches modern carbon cockpits while remaining just as durable.

Each set includes five spacers of varying heights, providing a total stack height of 58 mm. This variety allows you to fine-tune your handlebar position to find your ideal riding posture.

Yes, these are precision-ground to ensure the top and bottom surfaces are perfectly parallel. This is critical for maintaining even pressure on your headset bearings, which prevents loosening and protects the integrity of your steerer tube.

You can mix them, but for the best results, we recommend using a consistent material throughout your stack. Using these precision-ground carbon spacers ensures a uniform fit that prevents the uneven stress often caused by mixing different spacer materials or manufacturing tolerances.
