Clamps for Stunt Scooters: A Comprehensive Guide
The main role of a stunt scooter clamp is securing the bar to the scooter fork. When selecting a clamp, factors like compression, compatibility and durability are important to take into account. Detailed explanations are provided here.
Scooter clamps are available in numerous designs and sizes, playing a crucial part in your scooter assembly. Making a wise choice in your scooter clamp can ensure it lasts for many years. Stay with us as we cover all you need to know about scooter clamps.
Overview
Various Clamp Options for Stunt Scooters
Three key attributes set different scooter clamps apart:
- Clamp Inner Diameter: It is vital that the inner diameter of the clamp matches the outer diameter of your scooter bar. Standard clamps usually feature an inner diameter of 32 mm, while oversized clamps come with a 35 mm inner diameter. For those with a standard-size bar, an oversized clamp paired with a compatible shim is also an option. Clamp shims are small tubes that adjust a clamp's inner diameter from 35 mm to 32 mm, allowing it to hold a standard bar securely.
- Number of Bolts: The terminology such as quad clamp, triple clamp, or double clamp indicates the quantity of bolts needed to secure the clamp. Quad clamps are typically used for SCS setups, although triple SCS clamps are available as well (using fewer bolts can reduce weight). Single and double clamps are generally suitable for HIC, IHC, or ICS setups.
- SCS and NON-SCS Clamps: SCS clamps incorporate the compression system within themselves. Many riders opt for them despite their heavier weight. Conversely, IHC and HIC clamps fall into the non-SCS category. For SCS compression, SCS clamps are necessary. When using an alternative compression system (such as ICS, HIC, or IHC), a non-SCS (i.e., a regular) clamp is required.
Understanding Standard vs Oversized Scooter Clamps
Typically, standard-sized clamps come with an inner diameter of 32 mm, aligning with the outer diameter of standard scooter bars.
Oversized clamps, conversely, have an inner diameter designed to match oversized bars. They can also accommodate standard bars with a shim to reduce the inner diameter accordingly. Many oversized clamps come with a shim included upon purchase.
When deciding between standard and oversized clamp diameters, the primary concern is compatibility. If you're planning to try different bar diameters, an oversized clamp offers greater versatility. Yet, if you're riding a standard bar and aim for the lightest configuration, a standard-sized clamp is preferable.

Choosing Between Double, Triple, or Quad Clamps
For HIC, IHC, and ICS setups where the bars are slitted at the bottom, it's advisable to select a durable dual clamp that does not extend above the slit to avoid damaging the bar. The two bolts provide sufficient reinforcement to secure the clamp, and dual clamps add minimal weight to your setup.
Stunt scooter SCS clamps are mostly quad clamps, as the additional bolts aid in distributing clamping pressure evenly over the top of the fork and the bottom of the bars.

When using a SCS clamp with a bar that includes a slit at the bottom, you have a couple of choices. You can use an SCS adapter or trim the bar. However, be aware that trimming the bar will nullify its warranty and result in a shorter bar.
Fixing Scooter Clamps
Tighten the compression before you secure the clamp, ensuring the wheel and bars are aligned before tightening the clamp.
Then, follow slightly varied methods for different clamp and compression types:
- HIC or IHC: Insert the bar through the clamp then attach the bar before securing the clamp bolts.
- SCS Clamp: Attach the clamp first, tighten the compression bolt, then mount the bar and secure the clamp bolts.
For even compression distribution, it's advised to tighten bolts gradually in a cross pattern rather than securing one bolt fully before moving on. For quad clamps, begin by gently tightening bolt 1, then bolt 3, followed by bolt 2, and finally bolt 4. This technique distributes compression evenly around the clamp area.
