Tyreinvader: anti-pinch flat insert for your tubeless tyres
 

Just cut Tyreinvader following the instructions (for 27.5” and 26”; no need to cut for 29”), join its two ends with the two (provided) zip-ties, mount it inside the tyre (it will stretch a little to fit the wheel circumference), add sealant, go ride!

Yes, you will need to add sealant. Tyreinvader has been designed to function great with our Caffélatex sealant, ammonia free, and Végétalex, our biodegradable sealant.

We use EVA, a closed cell polymer commonly used for sport shoe soles, with very high energy absorption and great mechanical properties.
For this reason, there's no particular "expiration date" for Tyreinvader, but we recommend to check Tyreinvader once a year or after hard riding sessions, and to replace it if needed.

No, Tyreinvader is compatible with any type of valve. The shape of Tyreinvader and a specific cut-out (to be positioned over the valve) make tyre inflation always easy, with any tubeless valve.
