Best Bike Headset Spacers Buying Guide
Before choosing the best bike headset spacers you should consider following options:
1. Material: You’ll find spacers made from aluminum, steel, plastic and even titanium.
Of these materials, aluminum is the lightest, but it’s also the most prone to damage. Steel is the toughest, but it’s also the heaviest. Plastic is the lightest and least expensive, but also the least durable.
Titanium is one of the toughest and lightest materials, but it’s also the most expensive.
2. Width: Most spacers are 1 inch in width, but some are 1 1/8 inches or 1 1/4 inches. The wider the spacer, the more stable the headset will be.
3. Length: You’ll also find spacers in different lengths. Longer spacers are used when you have a longer stem and want to move it back. Shorter spacers are used when you want to lower the stem.
4. Thread type: You’ll find spacers with either a single or a double thread.
If you want to move your stem forward, you want to use a spacer with a single thread because the headset will tighten against the spacer.
On the other hand, if you want to move your stem backward, you want to use a spacer with a double thread so that the headset can tighten against the lower headset cap.
If you move the stem backward and tighten the upper headset cap, the spacer won’t move forward because the lower headset cap will be moving backward with the same amount of force that the upper headset cap is moving forward.
This will cause the lower headset cap to rotate on the crank arm, which can damage the bearings.
What else you should know about bike headset spacers
1. What is a bike headset spacer?
A bike headset spacer is a small metal or plastic ring that is placed between the top of the fork steerer tube and the headset top cap. The purpose of the spacer is to take up any excess space between the two components, and to provide a small amount of pre-load on the headset bearings.
2. What are the benefits of using a bike headset spacer?
Bike headset spacers are used to fine-tune the handlebar height on a bicycle. They are also used to make the handlebar stem longer or shorter.
3. How do you install a bike headset spacer?
Bike headset spacers are generally installed by hand, although some riders may use a small wrench or other tool to help with installation. First, determine how many spacers are needed to achieve the desired handlebar height. Next, remove the top cap from the fork, and carefully thread the spacers onto the steerer tube. Finally, replace the top cap and tighten it in place.
4. What is the best material for a bike headset spacer?
There is no definitive answer to this question as it depends on personal preference. Some people prefer to use metal spacers for their bike headset, while others prefer to use plastic or even wooden spacers. Ultimately, it is up to the individual to decide what material they feel works best for their needs.
5. How do you remove a bike headset spacer?
There is no one-size-fits-all answer to this question, as the method for removing a bike headset spacer will vary depending on the type of headset you have. However, in general, you will need to use a headset wrench to loosen the top cap of the headset, which will allow you to remove the spacer.
