Frequently Asked Questions (FAQs)

1. What size headset spacers do I need?

When choosing headset spacers the most important thing is to match the size to the diameter of the fork steerer tube. The most common steerer diameters are 1”,1 1/8”, 1.5” and tapered.

2. Can you put spacers under the headset?

You CANNOT put spacers under the head tube. The bottom cup of the headset has to fit snugly in the head tube, and the steer tube of a fork is a little broader at the bottom to fit the base plate of the headset. There's no safe way to change these relationships.

3. How tight should headset spacers be?

A god rule of thumb is to tighten your headset cap bolt until it is causing some friction with steering and then back it off until it's tight enough to keep the stack neatly in place. This is typically 1/8th to 1/4 of turn. Give your headset spacers a twist. You should not be able to move them much, if at all.

4. Do you need spacers on steerer tube?

The clamp bolts of the stem on the steerer tube in a threadless headset setup are what holds the whole assembly together. Spacers below the stem are required to eliminate vertical play. Spacers above the stem are only required for aesthetics.
