Aeron SuperLite Race 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. However, if you want to get the best possible performance out of yourself and your bike, the SuperLite Race is your ideal ally. Features of the Aeron SuperLite Race MTB tube - 27.5/29" | 1.7-2.5" Protection Level 3: A good balance of puncture protection, low weight and low rolling resistance Very good puncture protection and rolling resistance combined with low weight and high air tightness Suitable for gravel and cyclocross racers as well as bikepackers and ultra riders Up to 63 percent lighter than conventional butyl tubes Approved for tire widths from 1.7" - 2.5" TPU valve stem for better grip of the pump head Multi-layer construction Thermoplastic polyurethane - the new material for bicycle inner 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.
