Headset Spacers for Your Cockpit Setup

Headset spacers help set stem height within your fork and stem's fit limits. Shop individual spacers and kits in aluminum and carbon, with color options from Wolf Tooth, Cane Creek, Wheels Manufacturing and other brands. They're a small part, but worth getting right when changing your cockpit or finishing a build.

Check Diameter, Height and Fit

Match the spacer's inside diameter to the steerer where it sits, then choose the heights you need. Many listings here are for 1-1/8-inch steerers, but check the individual specification. Some spacers use a shaped or interlocking interface, so confirm they work with your headset and existing spacers.

Follow your fork and stem manufacturers' requirements for spacer arrangement, steerer engagement and maximum stack height, especially with a carbon steerer. Adding spacers can't make a steerer that's been cut too short suitable for a higher stem position.

Check whether the listing is for one spacer, a multipack or a mixed-height kit. If you're also changing the stem, browse mountain bike stems or ask us about your current setup.
