Bike Headsets

Two generations

Old bikes and some city bikes use a threaded headset, like the chrome headset V Bike: the cups screw onto the fork steerer, and the quill stem tightens inside. Modern bikes use a threadless headset, or ahead, where the stem tightens around the fork steerer and adjusts the bearing preload via the top cap.

The other components

The components are also available as:

• Stems.
• Spacers.
• Handlebars.
• Clamps.
• Adaptors.
• Seat posts.
• Saddles.

All the components can be found on the peripheral components page.

The FSA models

On an integrated headset, like the FSA Orbit, the bearings sit directly in the frame. Three points are checked: the diameter of the bearing, the angle of its seat, thirty-six or forty-five degrees depending on the frame, and the height of the top cap, which affects the height of the handlebar setup. The diameter of the fork steerer, typically one inch and an eighth, must also match.

The replacement

A headset with external or semi-integrated cups, like the Funn Descend or Enduro bearings, requires a press to install the cups properly and a tool to fit the crown race: a task often done by a workshop. An integrated headset is easier to replace. You grease the bearing seats, adjust the preload without play or tight spots, then tighten the stem to the proper torque.

The good deals

Good deals can also be found in the good deals, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped in 24h are prepared and dispatched within 24 hours. The key events of the year follow in a stable order: the Black Friday at the end of autumn, the end-of-year holidays, the winter sales, the French Days in spring, followed by the summer sales and back to school.

Frequently asked questions

How to know the size of your headset?

You measure the diameter of the fork steerer, usually one inch and an eighth on modern bikes, one inch on older ones, and the type of frame housing: external, semi-integrated, or integrated. The specs are often on the cups.

How to tell if a headset is threaded?

On a threaded headset, like the chrome headset V Bike, a cup screws on top of the head tube, locked by a locknut, and the quill stem drops inside the fork steerer. On a threadless headset, the stem grips the fork steerer from the outside.

What signs indicate that a headset is worn out?

A headset that clunks when braking, steering that catches or locks in a straight position, or squeaking when turning are signs of worn bearings. They should be replaced without delay, as handling precision depends on it.

Can you change only the bearings in your headset?

Yes, on integrated headsets, like the FSA Orbit, the cartridge bearings can be changed individually, provided that their diameter and angles are respected. Enduro Maxhit bearings, designed for durability, are a good option.

Is a specific tool needed to install a headset?

The cups of an external or semi-integrated headset are pressed into the frame using a dedicated press, and the crown race is removed with a suitable tool. An integrated headset, installed directly into the frame, can be set up with minimal tools.
