Installation

How is an Aeron TPU airtube installed?

Installing AERON TPU airtubes is just as easy as with butyl tubes. Remove the tire bead on one side, insert the inner tube, pump it up slightly (no more than 4 psi), reinstall the tire bead onto the rim, inflate the tire fully and you‘re done. The ease of installing the tire is the great advantage of the TPU inner tube over tubeless systems. Many cyclists shy away from the complicated tubeless installation - and rightly so. You must be reasonably experienced to convert your wheels to tubeless, and for a large puncture that the system cannot seal with sealant, you are faced with quite a mess.

Why do Aeron TPU airtubes need to be pumped up carefully at the beginning?

To aid in easy installation of the tube into your tire, the tube should be slightly inflated (4 PSI max) with a small amount of air. However, overinflating can damage the product as the tubing is made of thermoplastic. Overinflating the tube outside of the tire deforms the tube. For example, when more too much air pressure is added to the product, this can result in irreversible bubble deformation.

Can Aeron TPU airtubes be inflated with CO2-cartridges?

Yes, but avoid bending the valve stem during inflation or directly after. The freezing temperatures involved with CO2 inflation can temporarily increase the risk of valve stem damage.

Can Aeron TPU airtubes be removed and reinstalled in another tire?

Yes, but please note that the air tube deforms and thus takes on the shape of the first rim and tire. It is therefore only possible to refit the air tube if the tire dimensions (wheel diameter and tire width) are the same.

Can I use talcum powder when fitting Aeron TPU airtubes?

The use of talcum powder is not a problem but is also not necessary due to the smooth surface of the air tube.

Can Aeron TPU airtubes be inflated outside the tire?

AERON TPU airtubes can be carefully inflated outside the tire until it is wrinkle-free and has a round contour. This corresponds to a maximum pressure of 4 PSI.

Can Aeron TPU airtubes be fitted with rim tape?

Mounting with rim tape is mandatory, as otherwise sharp-edged spoke nipples or incorrectly deburred rim holes could damage the air tube.
