ICS Compression Kit

Utilise this kit to ensure harmony between your bar and fork.

This Compression Kit includes a star nut and bolt.
Compatible with threadless forks and guarantees a stable fit with a threadless headset.

The star nut is inserted inside the bar (District bars come with a star nut already installed; however, you will still require the bolt). Subsequently, mount the bolt from bottom to top in the fork's top using a long allen key.

Designed for District forks, yet it is possible to fit other brands too.
Please note: Not compatible with Blunt Envy forks as they need a very long bolt (this can be resolved by purchasing a 300 mm long 6mm threaded rod with a few nuts and using it alongside the District star nut)
