Stunt Scooter Compression Systems Explained
The compression system is what holds the fork, headset and handlebars together on a stunt scooter. It keeps everything tight while still allowing the bars to spin smoothly. There are several types of scooter compression systems, each designed for different types of handlebars and riding styles.
In this guide we’ll explain the most common compression systems and how to choose the right one for your setup.
What Does Compression Do?
The compression system sits around the fork and headset.
Its job is to:
• keep the headset tight
• stop the scooter from rattling
• allow the handlebars to spin smoothly
Without compression, the scooter would feel loose and rattle like a bag of bones.
The Main Scooter Compression Systems
Most modern stunt scooters use one of these four compression systems:
• IHC (Internal Hidden Compression)
• HIC (Hidden Internal Compression)
• SCS (Standard Compression System)
Each system works slightly differently and is compatible with different handlebars.
IHC Compression
IHC is one of the most common compression systems on complete stunt scooters.
It uses a smaller fork tube and is designed to work with standard diameter and aluminium handlebars.
Pros
• lightweight
• simple design
• common on complete scooters
Cons
• not compatible with oversized bars without converting
• less durable than some other systems
Best for: beginner and park setups.
HIC Compression
HIC is a popular compression system used on many custom scooters.
It uses an oversized compression shim and is designed to work with oversized handlebars (34.9mm) like steel and titanium.
Pros
• strong and reliable
• simple to maintain
• popular for custom builds
Cons
• slightly heavier than IHC
Best for: intermediate and custom scooters.
SCS Compression
SCS is one of the strongest compression systems available.
Instead of a traditional clamp, SCS uses a four-bolt clamp that also acts as the compression system.
Pros
• extremely strong
• very reliable
• popular for street riding
Cons
• heavier than other systems
• requires SCS-compatible bars
Best for: street riders and durable setups.
Good to know...
Handlebars and forks can be used with multiple different compression types. You'll see a lot of forks listed as SCS / HIC, this is because the diameter of SCS and HIC forks are the same and can often be used for both compression types.
You can sometimes ride IHC forks with HIC compression bars. For example, an oversized set of Titanium bars on an IHC fork. However, this requires a conversion kit, which makes up the difference between the smaller IHC fork and the larger HIC bars. Not all conversion kits are compatible with all forks, and we recommend a direct compression match where possible.

Which Compression System Is Best?
There isn’t one “best” compression system. The right choice depends on your setup and riding style.
• IHC – common on complete scooters
• HIC – popular for custom builds
• SCS – strongest option for street riding
As long as your parts are compatible, each system works very well.
Compression Compatibility
Compression systems must match your:
• handlebars
• fork
• clamp
Before upgrading parts, always check compatibility with your current setup.
If you're unsure, see our Scooter Parts Compatibility Guide.
When Should You Upgrade Compression?
You may want to change compression if:
• you're switching to oversized handlebars
• you're building a custom scooter
• your current compression system is worn out
Many riders upgrade when moving from a complete scooter to a custom setup.

Frequently asked questions
There is no single best compression system. IHC, HIC and SCS are all widely used. SCS is often considered the strongest, while IHC is lightweight and common on complete scooters.
Yes, but your fork, bars and clamp must all be compatible with the new compression system.
No. Different compression systems require specific forks, clamps and handlebars. However, there is conversion kits that you can get to overlap some compression systems.
Most complete stunt scooters use IHC compression because it is lightweight and simple.
HIC and IHC compression work in a similar way but use different fork sizes.
HIC uses a larger fork tube and works with oversized handlebars, while IHC uses a smaller fork tube designed for standard aluminium bars.
IHC is usually found on complete scooters, while HIC is more common on custom builds.
