Also take a quick glance at the headset before you install it. Double check to m ake sure you have the correct headset to fit your bike. Grease The Top And Bottom Headset Cups The next step is make sure everything is properly greased before pressing in the headset cups themselves. We like to use Maxima Waterproof Grease , and with any kind of applicator, apply a thin layer of grease on both headset cups and the dust cap as shown below.
On the dust cap specifically, it is easy to apply too much grease. When the headset is filled with too much grease, some will make it out the side of the top cap and start to collect dirt when riding. The Maxima grease is great because it likes to stick around even after washing your bike.
We always recommend installing one headset cup at a time. This makes it much easier to ensure the headset cups are each aligned properly. This is even more relevant for those installing an offset headset. First place the top headset cup in to place and aligned correctly. Slide the Park Tool Headset Press in to place and slide the bottom collar up until it clicks in to position. Tighten the handle snug until the headset cup is flush with the top of the head tube.

The threaded headset was once the common headset design for most bicycles. Bearing cups are pressed into the bike head tube.
The bearings, which may be loose ball bearings, retainer ball bearings, or cartridge bearings, sit above and below the pressed races. The top most bearing-race has internal threading, and is held in place by a threaded locknut. The stem has no effect on the headset adjustment. Threaded headset sizes are designated by the outer diameter of the steering column. This can seem confusing, because the head cups do not measure the named standard. The various standards are generally not interchangeable.
For more on threaded headsets including the various standards see Threaded Headset Service. Threadless headsets have many of the same features as Threaded Headsets. Bearing cups are pressed into the bike headtube. The steering column has no threading. The top race uses an internal centering sleeve on the column to maintain alignment to the bearing cup. Pressure is applied to the top race from the stem. Threadless Headsets must use a compatible stem that matches the steering column diameter.
The stem binds to the outside of the column, and holds the top race in adjustment. For more on conventional threadless headset including the various standards see Threadless Headset Service. This type of headset system has, unfortunately, several names. The low-profile, zero-stack, integrated-with-cups, semi-Integrated, or internal-headset systems use pressed frame cups that act as a holder for the bearings. The cups have a flange, or lip, and sit adjacent to the outer edge of the top and bottom of the headtube.
The headtube is a relatively large outside diameter, approximately 50mm, and cups allow the bearings to sit flush or even inside the headtube. Some models use a cup that holds a cartridge bearing. The cartridge bearing is a slip fit into the cups. The cups act as a bearing holder and do not take bearing movement or wear directly. These are simply replaced as a unit when it is worn out.
