Types

Threaded Headsets: Older style, typically found on vintage bikes, with a threaded top race that screws onto the steerer tube.

Threadless Headsets: Modern standard, with bearings that sit in cups pressed into the head tube, secured by a compression system (stem and spacers).

Bearing Types

Loose Ball Bearings: Individual balls in a retainer or cup, economical but less durable and harder to maintain.

Cartridge Bearings: Sealed units with balls inside a metal or plastic housing, easier to replace and more resistant to dirt/water.

Sizes

Headset bearings vary in size, often specified by the head tube diameter (e.g., 1-1/8” for threadless, 1” for older threaded systems).

The SHIS (Standardized Headset Identification System) standard (e.g., EC34/30, IS41/28.6) helps identify compatible bearings.
