Continental launches lightweight TPU inner tube for bicycles

ContinentaTyre firm Continental has launched ContiTPU, an addition to its inner tube range created for both performance-focused and space-conscious cyclists. Available in a wide range of sizes from 25/35 – 622, Continental adds it has deployed the “highest” grade of micrometer-thick TPU (thermoplastic elastomer) across seven sealed layers to maximise airtightness and durability.

The tubes are uncoloured to further ensure material quality and prevent air retention issues caused by dye-related surface imperfections. Every ContiTPU tube is quality-checked post-production.

The base of the valve shaft is slightly conical in shape to improve fit to the wheel rim and reduce unwanted movement, while the valve is internally threaded to allow for the use of valve extensions or a replacement valve core.

The German company says every ContiTPU tube, inclusive of raw materials, is made in Germany. A repair patch is also supplied with every pack.

Hannah Ferle, Road Product Manager, Continental Tires, said: “Continental’s new TPU tube combines highest-grade materials and innovative production technologies to deliver a product that is not only the lightest within our tube portfolio but also the one with the smallest packing size. These were the two main characteristics we focused on in the development process and why I think that the TPU tube is great for every cyclist, whether it is someone focusing on performance and seeking to reduce weight and lower rolling resistance, or someone who simply wants to have the space to load their jersey pockets full of snacks for a long day on the bike, much like myself.”
