CushCore is an engineered foam insert that sits inside a mountain bike tire against the rim. It divides the inner volume of the tire in half, with air underneath the tread as normal, and the CushCore insert next to the rim. This provides an amazing damper for your tire, reducing the sudden unwanted spring back that you get from normal pneumatic tyres. CushCore absorbs shock, protecting your rim from sudden impacts and preventing pinch flats. The support it gives to sidewalls eliminates excessive tyre roll in corners, meaning you no longer have to run heavy, stiff tyres to get the casing stability required for aggressive riding. CushCore also acts as a mechanical bead lock, anchoring the bead inside the rim so that tyre burping is highly unlikely.

This system is designed to be used with tubeless-ready or tubeless converted mountain bike rims and tires. The material is also waterproof, compatible with tubeless tyre sealant, and tuned for appropriate rebound feel. Unlike most puncture protection systems, this foam is not destroyed in a single impact. Its ability to withstand repeated impacts without damage is more typical of foams that weigh twice as much. CushCore inserts are manufactured in Canada to tightly controlled quality standards.

A customised tubeless air valve is included with each insert. The air valve allows air to move through the valve without becoming obstructed by the insert.

Each CushCore insert is born in a huge aluminium mould, a manufacturing process which allows us to create the unique, patent-pending shape. The shape helps secure the tire to the rim, and extends well beyond the rim flange to protect against impacts from all angles. CushCore's special shape also creates the lateral force against the tire sidewalls that gives CushCore the cornering stability and calm ride feel it's known for.

“Hey guys, just some quick feedback to let you know (and give thanks) that CushCore definitely saved my race here in Madeira.”

• Protects the rim from sudden impacts, prevents pinch flats
• Supports the sidewall - increases cornering ability by eliminating excessive tyre roll
• Run lighter tyres
• Acts as a mechanical bead lock which stops burping
• Acts as a damper to minimise the spring back from impacts to the tyre
• 2 CushCore inserts
• 2 customised tubeless air valves
• Installation instructions
• CushCore is compatible with your current tubeless tires and rims
• Fits tyre widths 2.1 - 2.6"
• Fits rims with internal width 22 - 35mm
• If your wheels are not tubeless ready, rim sealing tape will be required
• We recommend the use of tubeless tire sealant (such as Stan's®) with CushCore
• Installation with certain tire & wheel combinations may require two people - one to work the tire levers, and another to hold the tire bead in the drop centre of the rim. Wire bead downhill tires are most likely to need extra help
• CushCore weighs about as much as a standard butyl inner tube
• 27.5" insert - 250 grams
• Potential weight reduction offset by using lighter tires and rims: 100-700 grams
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 tire sealant. Service life will depend on your riding frequency, terrain, etc.
