Tyreinvader is an anti-pinch-flat insert for tubeless tyres. Very simple to use and light, it saves your tyres and rims from hard impacts without interfering with the way your wheels behave. Available in several widths, to fit rims and tyres from cyclocross to Gravel to Plus.
- Very light weight (starting at 53g for one 29” wheel) and high durability.
- Premium material (high density EVA) absorbs shocks but not sealant.
- Can be easily adapted to common wheel diameters (26”, 27.5”, 29”).
- No need for specific tubeless valves.
Why we created it
People riding aggressively on rocky terrain would often like to reduce tyre pressure for better traction and control, limited by the worry of “hitting hard”, pinching the tyre casing between the rim and a rock, cutting it and/or damaging the rim. That’s where tyre inserts (anti-pinch-flat inserts, tyre noodles, etc.) can be helpful. These product fit inside tubeless tyres and absorb a part of the impact, protecting tyre and rim. With Tyreinvader we want to offer an excellent yet simple solution, keeping weight and cost low
The weights for the different Tyreinvaders refer to the product uncut (for 29” wheels), so it’s even lower when adapted to 27.5” or 26” wheels.
Great durability thanks to premium material
Tyreinvader is made of high density EVA (ethylene-vinyl acetate), a closed cell polymer commonly employed by the sport shoe industry: this material can resist heavy impacts with very little damage and is very durable.
We recommend to check Tyreinvader once a year or after hard riding sessions, and to replace it if needed.
EVA has a closed cell structure that cannot absorb any sealant, letting it free inside the tyre cavity.
Besides, the cut-outs of Tyreinvader allow the sealant to easily move around, to make sure punctures can be quickly fixed.
As inserts have surfaces that are wetted by the sealant, a fraction of it won’t be available to repair punctures. For this reason – also with Tyreinvader – we recommend to slightly increase the quantity of sealant normally employed, by 30 ml.
The cut-outs on Tyreinvader allow the sealant to move freely inside the tyre cavity, something that is much more difficult when using solid “donut-shaped” inserts.
Tyreinvader has been designed to function with our Caffélatex sealant, ammonia free.
Real run flat behavior
Tyreinvader has been sized to sit tightly on the rim, so that – in case of emergency – it will push the tyre against the rim, allowing to ride short distances on the flat tyre. This should be considered an exceptional functioning mode, as we don’t recommend to ride Tyreinvader at zero pressure on purpose.
Compatible with any tubeless 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. No need for special tubeless valves.
Reduced influence on normal riding
Tyreinvader is flat and it will basically come into play only when needed (unlike round inserts that are compressed quite often during normal riding). We still recommend to test ride Tyreinvader before racing with it.
We don’t encourage the use of lighter tyres nor of much lower inflating pressure: Tyreinvader simply allows to set tyres up the way the rider likes them, without worrying about pinch flats.
Tyreinvader is sold in pairs (so 2 pieces per pack, including 4 zip-ties to assemble them), inside a transparent bag. This bag can be used to safely store Tyreinvader after removing it, to avoid sealant stains. It can also be used for other purposes, like shopping or carrying little items.
Easy to assemble and mount
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.
Our Tech Videos can help clear any doubt.
If needed, Tyreinvader can be first mounted on the wheel without tyre, to stretch and make successive mounting easier.
Effetto Mariposa was born in 2007 with Giustaforza, the first torque wrench specially designed for cycling. Why did we do it? Because we think that every bicycle equipped with high-end components deserves a professional maintenance, with professional tools. After more than ten years, Giustaforza is still the benchmark in the industry.
Today, Effetto Mariposa specializes in bicycle torque wrenches, accessories for tubeless tyres, visco-elastic protective films and much more. Everything is designed and developed for cycling purpose. Effetto Mariposa is located just outside Lugano, Cantone Ticino (Switzerland).
