CushCore is an engineered foam insert that mounts inside a mountain bike tyre. It divides the inner volume of the tyre in half, with air underneath the tread and the CushCore insert next to the rim.

The purpose of Cushcore is to improve the ride quality of your bike. It is not just for flat protection. CushCore absorbs shock, stops deflection off obstacles, reduces vibration, and stabilizes the tyre against roll and squirm. Think of it as suspension for your tyres designed to give you a faster, smoother ride.

Although single liners are available, CushCore is designed to be used as a set.

This product contains:

1 CushCore Insert
1 CushCore Tubeless Air Valve
Installation Instructions

COMPATIBILITY

CushCore is compatible with your current tubeless tyres and rims
If your wheels are not tubeless ready, rim sealing tape will be required

We recommend the use of tubeless tyre sealant with CushCore

Installation with certain tyre & wheel combinations may require two people - one to work the tyre levers, and another to hold the tyre bead in the drop center of the rim.

Wire bead downhill tyres are most likely to need extra help.

CushCore inserts are extremely durable.  Our foam is engineered to withstand repeated pounding and flexing without degradation.  It does not absorb liquid and is not affected by tyre sealant.  Service life will depend on your riding frequency, terrain, etc. 

CushCore tubeless air valves are specially designed to work with a CushCore insert.

The air passageway is T-shaped, rather than a simple through-hole, which prevents the insert from obstructing air flow through the valve.

The valve body is CNC machined from 6061 T-6 aluminum, anodized black, with a tapered rubber collar permanently bonded at the sealing interface.

The valve core can be removed to add tyre sealant. A locknut with o-ring seal and valve cap are included.
