Aeron/TPU represents a genuine technological leap in bicycle inner tubes – Made in Austria with innovative TPU material. These tubes are two-thirds lighter than conventional butyl models while offering superior durability and significantly lower rolling resistance. Thermoplastic polyurethane (TPU) ensures extreme resilience and full recyclability – sustainable from the first to the last kilometer. Perfect for road bikes, gravel, or MTB: Aeron/TPU makes every ride lighter and faster.

Aeron TPU Bicycle Tubes
Aeron – TPU is conquering the cycling world!
For over 100 years, cyclists have relied on bicycle inner tubes made from butyl – an area in which comparatively little has changed over that time. Just like back then, they are still heavy, bulky, and also offer suboptimal rolling resistance and puncture protection.
TPU puts an end to that and is the revolution in bicycle inner tubes. Aeron is one of the pioneers in this field, making your tire setup lighter, faster, and more puncture-resistant.
Weight
TPU tubes are up to 80% lighter than butyl. Together, both tubes can save around 200 g on a road bike and up to half a kilo on MTBs. While this kind of weight optimization can easily cost several thousand euros when it comes to components like frames or wheels, it is possible with TPU for well under €100.
The lightest tube in the Aeron range weighs just 34 g and is therefore almost literally as light as a feather.
Pack Size
The low weight comes from the fact that TPU tubes are incredibly thin. Another advantage: their extremely compact pack size. When rolled up, they take up only a fraction of the space of normal tubes and can easily be stored in any saddle bag or jersey pocket without getting in the way.
Especially when bikepacking, this means you can carry several spare tubes – for an extra level of safety on the road or trail.
Puncture Resistance
Many people may now think that such thin tubes are fragile high-performance products that give up at the mere sight of a pothole. Far from it!
Despite their thin construction, TPU tubes are significantly more puncture-resistant than conventional tubes and reduce the number of stops needed at the roadside. If it does happen, they require less pressure than normal tubes and can therefore be inflated easily with a mini pump or cartridge.
Rolling Resistance
The thick surface of butyl tubes creates more friction inside the tire and therefore worse rolling resistance. Losing valuable power this way is especially frustrating – because it can amount to as much as 10 watts.
TPU generates significantly less friction and comes very close to latex tubes in terms of rolling resistance, without taking on their major disadvantages such as lower puncture protection and more difficult installation.
Less Pressure for More Comfort
The trend in cycling is moving toward ever wider tires with lower air pressure. This is being used very deliberately, especially in road cycling and gravel riding. However, such low pressures are only possible to a limited extent with butyl tubes, because under hard impacts they give way too much, which can damage the rim.
TPU tubes allow these lower pressures and noticeably improve comfort – in some cases even rolling resistance as well. Between rides, the material also loses less air, so pumping them up again is only rarely necessary.
We are engineers, we are cyclists
The brand uses this motto to describe its employees. In addition to striving for the perfect performance tube, they are all united by a passion for cycling. Everyone on the team knows exactly what matters and what a product must deliver in order to provide real added value for fellow cyclists.
The result is intended to be the lightest, most puncture-resistant, and best-rolling tubes on the market – for everyday riding, training, and racing.
Sustainable and Regional
Cycling is generally one of the most sustainable ways to get around – especially when it replaces car travel. Unfortunately, not all materials used in the cycling world follow this example. Carbon products, for instance, require an extremely high amount of energy to manufacture and are also not recyclable.
Fortunately, things look different when it comes to inner tubes: both TPU and butyl tubes are recyclable. However, TPU performs slightly better in terms of sustainability, since the material can be produced more energy-efficiently and, thanks to its thin construction, significantly less material is needed. Water consumption is also much lower for TPU tubes.
What makes Aeron special: the company is based in Austria and also manufactures there. This ensures optimal quality control, short transport routes, and is better for the environment compared to production in Asia.
The Right Tube for Every Discipline
Aeron wants to revolutionize the inner tube market on every terrain. That is why we at Bobshop offer a strong selection from this manufacturer – for road cycling, gravel, and MTB.
