Compression systems
When it comes to scooter bars, it's important to understand compression systems to know which bar to use for which scooter. You can read about the three different compression systems below. On all scooters on our website, it will be stated which system is suitable for the specific scooter. For more info, check out our scooter bar guide here!
ICS (Inverted Compression System):
ICS is a compression system often used in trick scooters. It involves a compression bolt that extends through the centre of the handlebar and screws into a star nut installed inside the fork tube.
With ICS, the handlebar must have an incision (cut) in the bottom to allow the compression bolt to pass through and make contact with the star nut.
This system is known for its simplicity and efficiency, but requires handlebar grips specifically designed for ICS compatibility.
ISC (Internal Compression System):
ISC is another compression system used in trick scooters, similar to ICS but with a different compression method.
In ISC, the compression bolt passes through the top of the fork tube and screws into a star nut or compression cap installed inside the fork tube.
Handlebar grips for ISC compatibility typically do not require a cut as the compression bolt does not extend through the centre of the handlebar.
IHC (Integrated Headset Compression):
IHC is a compression system that integrates the compression mechanism with the headset bearings of the scooter.
With IHC, the compression bolt screws directly into the top of the fork tube, eliminating the need for a star nut or compression cap inside the fork tube.
Steering levers compatible with IHC do not require a cut as the compression bolt does not extend through the centre of the handlebar.
Each of these compression systems has its benefits and considerations, and the choice between them often comes down to personal preference, compatibility with the scooter's components and desired setup of the scooter. Riders should ensure compatibility between the handlebars and the compression system when assembling or upgrading their trick scooter.
