Wolf Tooth Headset Stack Spacer

These spacers are designed for 1-1/8 inch top steerer tubes, which is the industry standard for most modern mountain and road bikes. As long as your steerer tube matches this diameter, they will fit perfectly.

The 6061-T6 aluminum construction offers superior structural integrity compared to plastic, ensuring your headset remains tight and secure under load. They also provide a precise, clean aesthetic that won't crack or deform over time.

These spacers are 5mm thick. If you are trying to dial in your handlebar height, you can stack multiple spacers to achieve the exact rise you need for your preferred riding position.

Yes, they are compatible. While many modern forks use a tapered steerer tube (1-1/8 inch at the top and 1.5 inch at the crown), these spacers only interface with the 1-1/8 inch section at the top where your stem clamps.

No special tools are required. You will simply need to loosen your stem bolts, remove the top cap, slide the spacers onto the steerer tube, and reinstall the stem and top cap to set your headset preload.
