In principle, a headset consists of two ball bearings that allow the fork and handlebar to rotate freely in the head tube of the deck. If you want a headset to turn well for a long period of time, proper care is required. You can clean a headset by removing the cover and removing any dirt from the balls. After that, you should remember to lubricate the bearing well (no oil) to minimize friction. But if you buy a headset with sealed ball bearings, they are maintenance-free and should not be opened.

Very importantly, the bearing set is always securely fastened by the compression system concerned. If this is not the case, the headset can be damaged and parts can break off very easily, destroying the balls and considerably shortening the life of the headset.

There are two main headset types in the scooter: standard threaded and threadless headset on the one hand, and semi-integrated and integrated headset on the other.

Nowadays, threaded headset assemblies are only designed for entry-level scooters manufactured on the manufacturer's side. This is for the simple reason that it is a cheap version and that the entry-level scooter must have low prices. We always have threaded headsets as a spare part for your entry-level scooter in the shop. The threaded headset is screwed on from the top via the threaded fork tube with two large nuts. This allows the fork and headset to be compressed, unlike the rest of the compression.

Threadless headset are the most common headset on the aftermarket or for custom scooters. These headsets are designed in a similar way to the threaded ones, without thread on the fork tube and the two nuts. The fork tube is smooth and connected to the stem via a separate compression system (ICS, SCS or HIC), so that the threadless headset also benefits from the necessary compression of the system. Threadless headsets consist of several parts, the two cups in which the bearings are located, the spacer ring on the bottom of the fork, two rings and a cover that forms the end of the headset.

Threadless headsets consist of a bearing seat (CrownRace), 2 ball bearings, 2 cups, 1 or 2 compression rings and a cap. First you push the cone onto the fork. Then install the upper and lower bearing cups in the head tube of the deck. If this is too difficult, you can get help at most bicycle repair shops with a special tool, or you can do it the conventional way by placing a piece of cushioned wood on the bearing seat and hammering it with a hammer. Then you simply push the ball bearings into the corresponding bearing seats, push through the fork, then put on the compression ring and then the cap.

Semi-integrated headsets are not very common and are therefore only used for a few complete scooters. The Grit and Crisp companies are an example of this. As we also sell these brands of scooters in the shop, we also offer semi-integrated headsets as spare parts. The main difference to integrated headsets is that there are still cups in which the sealed bearing rings are located. Semi-integrated headsets only fit compatible scooters and cannot be installed anywhere else.

Integrated headsets are the newest and simplest variant on the market.

Please note: Integrated headsets are only suitable for integrated decks and cannot be placed anywhere else.

With the integrated headset, the number of parts to be installed is reduced because the cups are already integrated in the head tube of the deck (hence the name integrated). These are formed in an additional manufacturing step on the head tube at the top and bottom, so that the bearing rings only have to be inserted.

In this case, everything is easier. First you push the cone onto the fork, then both ball bearings in the integrated deck and you can push through the fork. Finally, the compression ring and then the cap on top. And it's done!

Make sure you never forget the compression ring, because you won't be able to tighten the headset without it : If this ring is not put on, the JDD will be damaged and the handlebar will turn badly.
