Wolf Tooth Headset Spacer Kit

These spacers are designed for standard 1-1/8 inch (28.6mm) steerers, which covers the vast majority of modern mountain and road bikes. If you are unsure, check your bike's specifications to confirm it uses a standard 1-1/8 inch threadless headset.

The kit includes four spacers in total: one 3mm, one 5mm, one 10mm, and one 15mm. This variety allows you to fine-tune your handlebar height with precision.

Yes, these aluminum spacers are safe to use with carbon fiber steerers. Just ensure your steerer tube is cut to the correct length so that the stem clamps securely onto the tube, not just the spacers.

Aluminum spacers offer a balance of durability and weight that is hard to beat. Unlike plastic, they won't crack or deform under pressure, and they are generally more affordable and robust than carbon fiber options while maintaining a clean, professional aesthetic.

Each spacer is laser-marked with its specific size, so you can easily identify and select the right one without needing to measure them yourself.
