CushCore Kit PRO 27.5" X 2.1-2.6" Tubeless Puncture Protection (Pair)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 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."
- 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 CushCore inserts . 2 customised tubeless air valves . Installation instructions Compatibility . 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 Weight. 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 Durability 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.

Good quality sound deadener at a good price.
Model: NewSLS50_52
Quality sound deadening that adheres to body panels well. You can easily hear the vibration reduction after just the first piece by tapping on the body panel before and after.

BUY THIS ONE!
Model: NewSLS50_52
This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ. Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that. Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.

Good stuff, but watch the temp
Model: NewSLS50_52
I used this in my single cab pickup truck (89 ford.) It only took half the box (10 sheets or 25 square feet) to do the floors, but I bought the big box because I plan to do the doors, back wall, and maybe the roof as well. One thing I learned is that the temperature matters when you’re doing the installation. It was around 55F when I started in the evening, and when it dipped down into the 40s the sheets would not stick to the metal, and were hard to compress with the roller. That’s why I ended up only doing the floors and not any vertical surfaces; i will have to wait for a nice hot day. The other thing is that the foil layer on top is razor sharp at the edges, definitely wear gloves! I didn’t notice until after but I have little papercuts all over my fingers. Aside from those things, the install was easy and straightforward. The sheets cut easily with scissors, and any goo that ends up on your hands or scissors can be cleaned up with acetone (nail polish remover), or lacquer thinner. I would use this stuff again.
