Don't just make upgrades to your wheels and tyres in the pursuit of speed, consider the inner tubes too. Descent's tpu inner tube are suitable for 35-50c tyres and boast faster rolling capabilities, two times improved puncture protection and over a 50% weight saving compared to a standard butyl tube. 

How is that possible? It's simple really, an innovative material has been utilised; TPU (Thermoplastic Polyurethane Elastomer). TPU has multiple properties - meaning that it is both hard and rigid whilst also being soft and elastic which reduces rotating mass where it matters for enhanced performance. 

Not only do TPU tubes offer enhanced performance, but they also are much more compact meaning that transporting 1 or two in a jersey or saddle bag is easier than ever! And, in the event that you do get a puncture, Descent TPU inner tubes come with 2 glue-less TPU puncture repair patches included in the box!
