Product Information
Full details
The CushCore Pro Tyre Insert Kit is designed for serious mountain bikers and enduro riders who want to elevate their bike's handling and protection. By transforming tubeless tyres into an active suspension component, it provides significant impact damping and improved stability, though users should be prepared for a slightly more challenging installation process compared to standard tubeless setups.

FAQs
Will these inserts work with all tubeless sealants?
Yes, the closed-cell polyolefin foam is designed to be impervious to all common brands of tubeless tyre sealant.
Can I use these on a non-mullet bike?
This specific kit is optimized for mullet setups (29/27.5). If you have a standard bike with two 29-inch wheels, you should purchase the dedicated 29-inch pairing.
Does this make the bike feel heavier?
There is a slight increase in rotational mass; however, most riders find the trade-off in control and rim protection is well worth the added weight.
Do I need special tools to install them?
No special tools are required, but tyre levers and the included valve core tool will make the process much easier.
Can I run lower tyre pressure with these?
Yes, CushCore provides increased stability that allows riders to safely run lower pressures for better grip without worrying about the tyre folding or burping.
Troubleshooting
Difficult to seat the tyre bead during installation
Ensure the tyre beads are pushed deep into the center channel of the rim, which is the smallest diameter part of the wheel.
Airflow restricted when inflating
Use the provided valve core tool to remove the core, or ensure the CushCore insert is not physically blocking the valve base hole.
Pros and Cons
Pros
- Significantly reduces rim damage from harsh impacts
- Allows for lower tyre pressures without stability loss
- Improved cornering control due to increased sidewall support
- Does not absorb or degrade when exposed to liquid sealant
- Perfectly suited for modern mullet mountain bike setups
Cons
- Installation can be physically demanding compared to tubeless tape alone
- Adds a small amount of rotational weight to the wheels
- Requires specific attention to rim and tyre width compatibility
Setup, Compatibility & Care
For optimal results, ensure your wheelset falls within the supported specifications: inner rim widths of 22mm to 35mm and tyre widths between 2.1 and 2.6 inches.
- Begin by removing your existing tubeless tyre and cleaning the rim thoroughly.
- Install the provided 44mm Presta valves, ensuring the seal is airtight.
- Carefully work the CushCore insert into the rim channel.
- Mount the tyre over the insert, using the valve core tool to remove the core for easier inflation.
- Once seated, check for uniform alignment before fully inflating.
Since the foam is impervious to sealant, maintenance is simple; just check your sealant levels periodically through the valve stem.
