Product Information
Full details
The Cushcore 29er Plus Tyre Insert Set is an essential upgrade for aggressive mountain bikers and trail riders seeking improved handling and rim protection. By acting as a dynamic suspension system inside your tyre, it effectively dampens impacts and stabilizes the sidewall for better cornering performance; however, users should be aware that the installation process requires more patience and manual effort compared to standard tubeless setups.

FAQs
Does the Cushcore insert change how much sealant I need?
Yes, you may want to add an extra 1-2 ounces of sealant to ensure adequate coverage as some is absorbed by the foam.
Can I use these with standard rims?
These are compatible as long as the rim's internal width falls within the specified 32mm to 45mm range.
Is it difficult to change a tyre on the trail with these installed?
It is more challenging than a standard setup, but manageable with proper technique and the right tyre levers.
Do I need to replace the insert if I get a flat?
No, the insert is durable. You can ride on the insert for a short distance to reach a safe area, which actually protects your rim.
What happens if the foam absorbs too much sealant?
The foam is closed-cell and does not absorb significant amounts of sealant, so it will not become waterlogged or heavy.
Troubleshooting
Difficult to seat the final section of the tyre bead
Ensure the rest of the tyre bead is pushed deep into the center channel of the rim to create as much slack as possible.
Air is not flowing into the tyre through the valve
Ensure the valve port is not being blocked by the foam insert; adjust the position of the insert relative to the valve stem.
Tyre feels sluggish or unstable
Double-check your tyre pressure; ensure you have enough pressure to support the insert's dampening characteristics.

Setup, Compatibility & Care
Installing Cushcore inserts is a precise process that benefits from using plenty of tyre lubricant or soap water to help the tyre beads slide over the insert.
- Compatibility Check: Ensure your rim internal width is between 32mm and 45mm and your tyre width is between 2.6 and 3.0 inches.
- Valve Installation: Use the included 44mm Presta valves, which are designed to allow air to pass through the insert effectively.
- Mounting: Seat one side of the tyre, insert the Cushcore foam ring, and then carefully seat the second bead using tyre levers if necessary.
- Care: Periodically check your tyre sealant levels, as the foam insert can absorb a small amount of fluid. Inspect the inserts for signs of excessive wear or degradation if you frequently ride in extreme, rocky conditions.
