How do I choose a spacer for my headset?

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.

Can I add spacers to my headset?

You can buy different size spacers and change up the order until you’re happy w/the result. If you like a result with spacers on top, but don’t want the spacers on top, you can have your local bike shop cut down your steerer tube to shorten it.

Do you need spacers on a headset?

No, you don’t need to run spacers between the headset and stem. It’s hard to tell what, exactly, you’ll need without actually putting everything together.

How do I know what headset fits my bike?

If you can see a headset cup outside of your frame, even just a flange or lip (as in the photo above) then your headset is Press Fit. If you can’t see a headset ie. it’s entirely sitting inside the frame head tube, then your headset is Integrated.

How many headset spacers should I use?

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 have too many headset spacers?

Nope. The maximum stress on the steerer will be around the top headset bearing. If the bars are in the same position relative to the headset, then the stresses on the steerer and headset will be the same for normal riding.

How do you remove a headset spacer?

Steps to follow:

  1. Remove the screw holding the top cap on with a 5mm hex key.
  2. Remove the one or two screws holding the stem onto the steerer tube (the steerer tube is the metal part of the front fork that feeds through the head tube).
  3. Remove the stem and if you want to lower it by 4 spacers, remove the four spacers.

When should I replace my bike headset?

If you’re experiencing play (unwanted movement) in your headset, or a rough grinding when you turn the bars, it’s likely that it’s time to service your headset or replace the headset bearings. Most modern bikes use two sealed bearings positioned at the top and bottom of the head tube.

What is the best seat position on a bike?

Ideally you want about a 3 degree bend in your knee while your foot is at the bottom of your pedal stroke (6 o’clock). If your saddle is too tall you will get a rocking sensation as you pedal that you’ll want to avoid. The handle bars are the second most vital contact point on your bike after your saddle.
