Headsets and Headset Accessories
The headset is an underestimated, yet very important component on the bike. Not only does it allow the bike to be steered in the first place, it also absorbs forces that occur when riding your bike over bumps, no matter how small, and act on the frame and the rider. An intact and well-maintained headset is essential for proper and safe handling. An incorrectly adjusted or defective headset not only makes handling more difficult, it can also lead to damage to your bike frame that is difficult to repair. The headset is a wear part that should be given some attention. Choosing the right headset for your bike is not always easy at first glance. There are basically different standard dimensions for headsets: 1", 1 1/8" as well as different tapered systems for tapered fork stems and head tubes on the frame. In addition, there are 2 different systematics with regard to the connection of stem and fork with resulting requirements for fork, headset and stem: the threaded headset for fork stems with external thread and stem with internal clamping and the Ahead headset for threadless fork stems and stems with external clamping. In addition, there are details such as positioning of the bearing shells in which the actual bearing sits (internal, external or both mixed) and various standards for the dimensions and angles of the bearing.
Choosing the right headset for your bike is not always easy at first glance. There are basically two different standard dimensions for headsets - 1" and 1 1/8". The two dimensions always refer to the diameter of the steerer tube. On classic bikes you will mostly find 1" threaded headsets. With these headsets, the fork is bolted to the headset and secured. This system is nowadays only used on frames inspired by classic bikes and has been replaced by the 1 1/8" Ahead system. In 1 1/8" Ahead headsets, the fork is not fixed in the headset, but with the help of a claw or an expander. In 1 1/8 "headsets there are now many "tapered" models. Tapered refers to the fact that the steerer tube is wider at the lower end than at the upper end and the frame accordingly. This widening leads to the fact that the bike can be steered more stable and controlled. Tapered headset, frame and fork must have the same dimensions.
The second key point of differentiation of headsets is the mounting of the headset in the frame. Basically, headsets are either press-fit or press-fit into the frame. Press-in headsets are often marked with an EC or ZS. Headsets with EC have the bearing cups outside the frame and those with ZS inside. However, with both standards, the headset's bearing cups are pressed into the frame. With headsets that are placed in the frame, you will find in the head tube pre-milled shells in which the bearing shells of the headset can sit securely and without slipping. These headsets can be mounted without tools and are very common.
To headsets always include accessories such as spacers, top cap and Ahead claw or expander. A claw is hammered into the top of the metal steerer tube and fixes itself in it. If the steerer tube is made of carbon, you must necessarily use an expander instead. The claw or the expander can be connected with a screw to the top cap and thus secure the fork in the frame. The correct installation of the claw or the expander is particularly central to the correct assembly.
