Puncture Repair (Clinchers/Tubes)
A practical puncture repair video for clincher tyres, plus an introduction to butyl, latex and TPU inner tubes.

There is much debate around what type of tyres work best and that’s something we’ll get into on future posts. However, for now this video will show you how to change a puncture in a clincher tyre. For those that are unsure, clincher tyres are tyres that have tubes inside.
There are three main types of tube to go inside a clincher:
1. Butyl
Easily the most common, the cheapest of the three and a solid choice. They can also be filled with sealant to help prevent punctures and are less messy than tubeless in that regard.
2. Latex
They also offer a high level of puncture protection from snake bites and foreign bodies. This is due to the talcum powder on the outside of the latex tubes. The powder prevents the tube from sticking to the tyre, allowing it to deform when poked.
3. TPU
Thermoplastic Polyurethane (TPU) tubes have become more popular in recent years thanks to their light weight and small pack size. TPU has characteristics similar to rubber and plastic, and is said to have the least rolling resistance compared to butyl and latex tubes. You can also use sealant with TPU but it needs to be specific to TPU and not Butyl.
