Headset spacers generally come in 2 common outside diameters, and even those can deviate a little bit. The White Industries Tapered Headset Spacer transitions from your headset cup to the narrower 31.8mm spacer design. We stock a variety of headset spacers that are in this narrower width; the SimWorks by Nitto steel and titanium spacers as well as the White Industries Anodized Headset Spacers are the two most common.
**Spacers are priced per item. If you are looking for the straight 31.8mm spacers click 'here'.
