Fork

The Velossimo.hu range includes components required for the correct installation of bicycle forks and steerer tubes. This category includes compression plugs, expanders, star nuts and other fork and steerer tube components for road, MTB and gravel bicycles.

Choosing the correct component is particularly important with carbon steerer tubes, where the appropriate compression plug or expander must be used according to the fork manufacturer's specifications.

Main Product Types

  • Compression plugs / expanders
  • Star nuts
  • Ahead system components
  • Expanders for carbon steerer tubes
  • Fork and steerer tube installation components
  • Other headset-related components

Compression Plug or Star Nut?

  • Compression plug / expander – primarily used with carbon steerer tubes and provides internal support when applying headset preload
  • Star nut – traditionally used with Ahead systems and generally installed in aluminium or steel steerer tubes
  • With carbon steerer tubes, not every expander is compatible with every fork, so the manufacturer's specifications must always be checked

How to Choose?

  • Check the steerer tube diameter
  • With carbon steerer tubes, use only a compatible compression plug / expander
  • Check the internal construction of the steerer tube and expander compatibility
  • Follow the manufacturer's specified maximum tightening torque
  • For star nuts, check the steerer tube material and required size

In Practice

The compression plug and other fork components play an important role in headset preload and secure handlebar and fork assembly. With carbon forks, the expander is particularly important because it provides internal support for the steerer tube during headset adjustment. Using the correct component and following the manufacturer's specified tightening torque is essential for safe and reliable installation.
