Stunt Scooter Parts Compatibility Guide
When building or upgrading a stunt scooter, it’s important to make sure all the parts work together correctly. Different compression systems, bar sizes, wheel sizes and deck standards can affect which components are compatible.
In this guide we’ll explain how scooter parts fit together, what to look out for when upgrading, and how to make sure your setup works perfectly.
The Key Areas of Scooter Compatibility
When building a stunt scooter, most compatibility questions come down to these main areas. Understanding these will help you choose parts that work together safely and smoothly. These are as follows:
- Compression System
- Bar diameter
- Wheel size
- Deck compatibility
- Forks compatibility
- Clamp compatibility
Compatibility Cheat Sheet Chart
If you're building or upgrading a stunt scooter, some parts must match specific standards in order to work together correctly. The quick guide below shows which parts affect compatibility and what you need to check before buying new components.
| SCOOTER PART | MUST MATCH WITH | WHAT TO CHECK |
|---|---|---|
| Bars | Compression system + clamp size | Bar diameter (standard or oversized) and compression compatibility |
| Fork | Compression system + wheel size | Fork type (IHC, HIC, SCS) and maximum wheel size supported |
| Clamp | Bar diameter + compression system | Standard (31.8mm) or oversized (34.9mm) bars and clamp bolt setup |
| Wheels | Fork + deck clearance | Wheel diameter (110mm / 120mm) and width supported |
| Deck | Wheel size + brake type + axle size | Maximum wheel size and compatible brake system |
If you're unsure whether your scooter parts will work together, check the product specifications or use our Custom Scooter Builder, which automatically filters compatible parts.
Compression System
The compression system is what holds the bars, fork and headset together while allowing the scooter to spin smoothly.
Different compression systems require specific compatible parts, including the correct bars, forks and clamps.
The most common stunt scooter compression systems are:
- IHC – lightweight compression system used on many complete scooters
- HIC – stronger system designed for oversized bars
- SCS – the strongest and popular system for street setups
Each system uses slightly different hardware, so it's important to make sure your parts are designed to work together. All parts available will specify which compression they are compatible with, so check out those product specifications!
Scooter Bars
Scooter handlebars come in two main diameters, which affect which compression systems and clamps they are compatible with.
Bars vary in:
• diameter
• height
• width
• material
The two main sizes are standard bars (31.8mm) and oversized bars (34.9mm). Choosing the correct bar diameter ensures your bars fit properly inside the clamp and compression system.
Bars will specify diameters and compression compatibility in the product specification, so match with your fork and clamp and you'll be good to go.
Wheel Size
Wheel size affects how your scooter rolls and determines whether the wheels will fit your fork and deck. Wheels fall into these categories:
- Standard wheels (110mm x 24mm)
- Larger diameter wheels (120mm x 24mm)
- Wide wheels (26-30mm wide)
Most stunt scooters use 110mm wheels, although some setups support 120mm wheels for slightly more speed.
When upgrading wheels, it’s important to make sure both the fork and deck provide enough clearance for the size you choose.
Deck Compatibility
The deck is the main platform of the scooter and determines several key compatibility factors when building a setup.
Decks influence compatibility with:
• wheel size
• brake type
• axle size
• fork clearance
Different decks are designed around different specifications, so it’s important to check that your wheels, forks and brake are designed to work with your deck.
Fork Compatibility
Scooter forks play an important role in compatibility, as they connect the bars to the front wheel and support the compression system.
Forks must match:
• compression system with bars
• wheel size
• axle standard
For example, IHC forks are designed for IHC bars, while HIC forks work with HIC bars. Forks also have wheel size limits, so it’s important to check they support the wheels you plan to ride.
Clamp Compatibility
The clamp secures the handlebars to the fork and compression system, keeping the scooter tight and stable while riding.
Clamps must match:
• bar diameter
• compression system
• bolt configuration
Most IHC and HIC setups use 2 bolt clamps, while SCS systems use 4 bolt clamps that combine the clamp and compression into one unit.
Choosing the correct clamp ensures your bars fit securely and your compression system works properly.
Example Compatible Scooter Setup
To make compatibility easier to understand, here’s an example of a typical stunt scooter setup where all the parts work together correctly.
- Bars → Oversized Titanium Bars
- Clamp → Oversized 2 Bolt Clamp
- Compression → HIC
- Fork → HIC Fork
- Wheels → 110mm x 24mm
- Deck → compatible with 110mm wheels
Common Compatibility Mistakes
Buying oversized bars with an IHC fork
IHC forks only work with standard diameter bars (31.8mm) unless a conversion shim is used.
Buying 120mm wheels that don’t fit the fork
Not all forks support larger wheels. Always check the fork’s maximum wheel size.
Using the wrong clamp size
Standard clamps won’t fit oversized bars. Make sure your clamp matches the bar diameter.

Frequently asked questions
Not all stunt scooter parts are compatible with each other. Compression systems, bar diameters, wheel sizes and clamp types must all match specific standards in order for the scooter to work properly. Before upgrading parts, always check the product specifications to make sure they are compatible with your current setup.
Bars, forks, clamps and compression systems must all match. Wheel size must also fit the fork and deck.
SCS is the strongest system, while IHC is common on beginner scooters because it is lighter and simpler.
Only if your fork and deck are designed to support 120mm wheels.
