Effetto Mariposa Tyreinvader (X2) Pcs 40Mm Tyre Insert (Rims Ext.W. 20-30Mm, Tyres 42-54Mm/1.5-2.1")

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

Characteristics:

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

Lightweight: 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.

• Tyreinvader 35 = 48 g
• Tyreinvader 40 = 53 g
• Tyreinvader 50 = 68 g
• Tyreinvader 55 = 80 g
• Tyreinvader 60 = 92 g

Tolerance on nominal weight is + / - 5%

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.

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 - 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.

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.

If needed, Tyreinvader can be first mounted on the wheel without tyre, to stretch and make successive mounting easier.

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 you to ride short distances on the flat tyre. This should be considered an exceptional functioning mode, as we don’t recommend riding 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.

Functional packaging: 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.

What about the little aliens and the arcade font?

Who doesn't remember SpaceInvaders? Even those who are too young for that can still learn about this staple in the video game history, and play it thanks to retrogaming. Besides, our product is actually invading the tyre, thus “Tyreinvader”.

The cut-outs serve several purposes: to save weight, to allow easy sealant flow and… to offer some cool branding/styling opportunities.
