Engineered Foam Inserts
Cush Core is an engineered foam insert that sits inside a mountain bike tyre against the rim. It divides the inner volume of the tyre in half, with air underneath the tread as normal, and the Cush Core insert next to the rim. This provides an amazing damper for your tyre, reducing the sudden unwanted spring back that you get from normal pneumatic tyres. Cush Core 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. Cush Core also acts as a mechanical bead lock, anchoring the bead inside the rim so that tyre burping is highly unlikely.

Tubeless Ready And Waterproof
This system is designed to be used with tubeless-ready or tubeless converted mountain bike rims and tyres. 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. Cush Core inserts are manufactured in Canada to tightly controlled quality standards.

Fully Custom Air Valves For Inserts
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.

Unique Patent Pending Shape
Each Cush Core 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 tyre to the rim, and extends well beyond the rim flange to protect against impacts from all angles. Cush Core's special shape also creates the lateral force against the tyre sidewalls that gives Cush Core the cornering stability and calm ride feel it's known for.

Australian Jared Graves Feedback On Cush Core
"Hey guys, just some quick feedback to let you know (and give thanks) that Cush Core definitely saved my race here in Madeira."
- Jared Graves, Team Specialized, Enduro World Series. 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 Includes . 2 Cush Core inserts . 2 customised tubeless air valves . Installation instructions Compatibility 27.5 . Cush Core is compatible with your current tubeless tires and rims . Fits tyre widths 1.8" - 2.4" . Fits rims with internal width 22 - 32mm . 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 Cush Core . 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 . 150 grams Durability Cush Core inserts are extremely durable. The 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

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.
Style: Ball, Size: Medium (Pack of 2), Style: Ball, Size: Medium (Pack of 2)
Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.
