Aeron ExtraLite Protect MTB Tube - 27.5/29" | 1.7-2.5" - SV

For performance-oriented mountain bikers - fast and safe Mountain bikers and their bikes, tires and tubes have to be able to cope with rough terrain. But of course there are gradations here too. A downhill route with rocks and roots is just crying out for an AERON/TPU UltraProtect tube, while Alpine crossers should choose the compromise between puncture protection and performance with the ExtraLite for the constant ups and downs. Features of the Aeron ExtraLite Protect MTB tube - 27.5/29" | 1.7-2.5" Protection Level 3: A good balance of puncture protection, low weight and low rolling resistance Weight saving of around 59 percent compared to conventional butyl tubes Offers great mileage and very good puncture protection Specially designed for MTB, E-MTB and E-SUV MTBs Robust, durable and reliable - exactly what you need for off-road excursions Multi-layer construction TPU valve stem for better grip of the pump head Thermoplastic polyurethane - the new material for bicycle tubes The old familiar products are being replaced by TPU tubes, because TPU has many advantages over the black rubber tube. But what is TPU anyway? Thermoplastics are plastics that deform when heated and solidify when they cool down. This property makes them ideal for the production of bicycle inner tubes, as they can easily adapt to any tire size and width. In addition, TPU inner tubes can be created. For example, they can be produced in multiple layers, equipped with more or less puncture protection and produced in any color - the TPU tube is an all-round artist.
