Do I need spacers on my headset?

Put simply, headset spacers enable you to easily adjust the height of your handlebars, which is an essential element of bike fit for BMX, MTB and road riders. In the particular case of the latter (road cycling), the correct bar height is key for comfort and performance.

Can I add spacers to my headset?

The first and easiest way to adjust handlebar height is by moving headset spacers. Headset spacers sit on the fork’s steerer tube and help pre-load the headset bearings during adjustment. Generally, most bikes have 20 to 30mm of headset spacers that can be moved freely above or below the stem.

Can you add spacers to a threaded headset?

You can use a single headset wrench: Screw the top race and adjust the headset. Then insert the spacer and (lightly) tighten the locknut. Don’t overtighten the locknut, otherwise, the spacer can jam.

Do I need a spacer under my stem?

There is no reason to have any problem due to no spacers under the stem. I rode two different bikes that way over four seasons. You see pictures of pro bikes setup that way all the time. It is wise, but not absolutely necessary to have a 2.5-5mm spacer on top of the stem.

How many spacers are under the stem?

Typical range with the right size bike for a normal rider is 0-3 cm of spacers below the stem.

Does headset stack height matter?

Yes as long as the part they’re measuring above and below the head tube are actually supportive – like threaded headset cups or threadless external headset cups pressed into the head tube. They actually structurally add to the length of the head tube, making it “longer”.

Why is my headset wobbling?

Headsets usually become loose because one of the headset pieces changed positions, or as a result of the stem and top nut loosening. To fix this requires tightening and locking the adjustment so it stays in place.

Do I need a spacer below my stem?

the headset and stem dont have friction. the spin together. the headset spins in the frame. so there is no difference between spacers under the stem, or none at all.

Do I need a spacer above my stem?

You should always leave some length of the steering tube above the stem and put a spacer above the stem so that the entire stem clamp is clamped around a cylinder of constant diameter.
