CushCore MTB Tyre Insert & Tubeless Valve Kit

Everything you need to get rolling with CushCore.

CushCore is the best foam tyre insert available for your mountain bike wheels. With CushCore you can spend your days hooning around the country side banging your wheels into stuff you know you're supposed to avoid and have a greatly reduced chance of getting a puncture and ripping your tyres off.

If you like how that sounds, you should also know that there's a whole lot more to CushCore than puncture resistance and rim protection. It's as much about ride quality, traction and cornering performance.

We highly recommend using Schwalbe Easy Fit mounting fluid during installation. It will honestly make the whole process much easier, and the money you save from the swear jar can be spent on more uplift days!
