Effetto Mariposa TyreInvader Tubeless Tyre Inserts 35mm

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.

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.

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. Effetto Mariposa recommend to check Tyreinvader once a year or after hard riding sessions, and to replace it if needed.

Sealant-optimized
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 - Effetto Mariposa 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.

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.

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 they 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.
