What Is a BMX Headset?
Headset is the part of your BMX that connects the fork to the frame and allows your handlebars to spin. Depending on the headset that you get, it might come with different parts/shapes however, they all come with bearings. There are two main types of headsets, the Integrated Headsets and Non-Integrated Headsets.
The most popular of the two types is definitely the integrated headset however, there are plenty of good non-integrated headsets out there.
Integrated or Non-Integrated Headset?
Integrated headset are named that way because of the sealed bearing rings that are placed in an integrated bearing holder which is built directly into the frame. It is a choice of the majority of riders, amateur and pro, as it is very simple to install and has a cleaner look to it than the non-integrated headset.
Non-integrated headsets have cups that are being pressed into the head-tube. The bearings are positioned over the frame and not integrated into it making this headset "Non-Integrated". With these headsets, there is less friction created when spinning the handlebars due to the unsealed bearings.
What Size Headset Should I Go With?
The most common BMX headset size is 1 1/8 Inches. Your BMX headset size should match the diameter of the fork steerer tube in order for it to fit. Some less popular models come in bigger sizes ranging between 1 1/4 - 1 1/2 Inches. In some cases of youth BMX bikes, you might find yourself with a smaller headset tube of 1 Inch.
