For those who demand the best; Vredestein latex inner tubes are made of 100% natural rubber. This inner tube has a highly elastic deformation of approximately 900% which means that punctures almost never happen. When a latex inner tube is fitted, the rolling resistance also reduces slightly.
This quality inner tube is made from Butyl which has a very low gas permeability which means the tube holds its pressure for longer. Less time spent at the pump!
Butyl inner tube which retains pressure well.
