Bike Headsets

The headset, a crucial element in the construction of a bicycle, is available in a variety of models but retains a basic structure: it consists of two races, one positioned at the top and the other at the bottom, which facilitate the movement of balls or bearings. This configuration allows for efficient transfer of the handlebar's rotation to the front wheel, ensuring a smooth and precise ride. Originally, headsets were external, with races housed in external cups on the steerer tube, then evolved to semi-integrated versions, and finally to integrated systems, where the bearings fit directly into the steerer tube. Although referred to as an evolution, the various types still coexist today, demonstrating the diversity of preferences and technical requirements in the world of cycling.

Choosing the right headset requires attention to specific technical details related to the bicycle frame. Let's explore the main aspects to consider together.

The original headset sizes were standardized to one inch, derived from hydraulic pipes adapted for cycling use. With technological advancement and the quest for more stiffness and lightness, diameters were expanded, reaching and exceeding one and a half inches, to better meet modern requirements and offer improved performance.

There are mainly two categories of headsets, distinguished by the method of installation on the frame:

- Threaded Headset: Traditional and historical, predominantly used until the 1990s and on budget or vintage models. Characterized by balls held in position by a locknut and a steel race system.

- Threadless Headset: Modern and prevalent in today's market, exclusively uses sealed bearings and is installed without threads, suitable for forks made from various materials, including carbon fiber.

Threadless headsets further differentiate in their installation on the frame, offering options such as the external, semi-integrated, integrated, tapered, and eccentric headset, each with specific characteristics to adapt to different riding needs and frame designs.

In conclusion, the choice of headset is not limited to size or type of installation but also includes aesthetic considerations and personalization, like headset caps, which can be chosen based on the color of the frame or to create contrast. Remember that the bearings can have an external angle of 36 or 45 degrees, an important detail for compatibility with your bicycle frame.
